10 Warning Signs You Should See a Cardiologist
Heart disease is the leading cause of death in the United States for both men and women. Yet many heart problems give early warning signs long before a heart attack or emergency. Recognizing those signs, and knowing when to see a cardiologist, can mean catching a problem when it is most treatable.
Here are 10 warning signs that mean it’s time to schedule a visit with a heart specialist.
1. Chest pain, pressure, or tightness
Chest discomfort is the most recognized sign of heart trouble. It may feel like squeezing, heaviness, or burning, and it may spread to your arm, neck, jaw, or back. Discomfort that comes on with exertion and eases with rest can signal angina, a sign that the heart isn’t getting enough blood flow.
Sudden, severe, or persistent chest pain is an emergency. Learn the full warning signs of a heart attack from the American Heart Association.
2. Shortness of breath
Getting winded with activities that used to be easy, or waking up at night short of breath, can point to heart failure, valve disease, or coronary artery disease. Needing extra pillows to breathe comfortably while lying flat is another red flag.
3. Heart palpitations or an irregular heartbeat
A racing, pounding, fluttering, or skipping heartbeat is often harmless. But palpitations that are frequent, prolonged, or come with dizziness or chest discomfort can signal an arrhythmia such as atrial fibrillation, which raises stroke risk if untreated.
4. Dizziness, lightheadedness, or fainting
Feeling faint or passing out can happen when the heart can’t pump enough blood to the brain. Causes include arrhythmias, a narrowed heart valve (aortic stenosis), and other structural heart conditions. Any unexplained fainting episode deserves a cardiac evaluation.
5. Swelling in the legs, ankles, or feet
Fluid buildup (edema) in the lower legs can happen when the heart isn’t pumping efficiently. Rapid weight gain of 2–3 pounds in a day or 5 pounds in a week, along with swelling, is one of the warning signs of heart failure.
6. Unusual fatigue
Feeling exhausted after ordinary tasks, or a steady decline in stamina, can be an early sign of heart disease. It’s one of the commonly overlooked symptoms of heart trouble, especially in women. Women’s symptoms often differ from men’s, so read our guide to women’s heart attack symptoms.
7. Leg pain when walking
Cramping, aching, or fatigue in your calves or thighs that starts with walking and eases with rest can be a sign of peripheral artery disease (PAD). PAD means plaque is narrowing arteries outside the heart, and it often signals blockages in the heart arteries too.
8. High blood pressure that's hard to control
High blood pressure often has no symptoms, but over time it damages the heart, brain, kidneys, and blood vessels. If your blood pressure stays high despite medication, a cardiologist can look for underlying causes and fine-tune treatment. See how high blood pressure damages your body.
9. Diabetes, high cholesterol, or other major risk factors
You don’t need symptoms to benefit from a cardiologist. Diabetes, high cholesterol, smoking, obesity, chronic kidney disease, and autoimmune conditions all raise your risk. Diabetes in particular roughly doubles the risk of heart disease. Learn how diabetes affects your heart.
10. A family history of heart disease
If a parent or sibling had heart disease at a young age (a father or brother before 55, a mother or sister before 65), your own risk is higher. Inherited conditions such as familial hypercholesterolemia, cardiomyopathy, and certain arrhythmias run in families. Early screening can find problems before symptoms start.
When to Call 911 Instead
Some symptoms can’t wait for an appointment. Call 911 right away if you have:
- Chest pain or pressure lasting more than a few minutes, or that goes away and comes back
- Chest discomfort with shortness of breath, cold sweat, nausea, or lightheadedness
- Fainting or a sudden loss of consciousness
- Sudden numbness, weakness, facial drooping, or trouble speaking, which are signs of stroke
Don’t drive yourself. Paramedics can initiate potentially life-saving treatment on the way to the hospital.
What to Expect at Your First Cardiology Visit
Your cardiologist will review your symptoms, medical and family history, and medications, then do a physical exam. Depending on what they find, your evaluation may include:
- Electrocardiogram (ECG) to check your heart’s rhythm and electrical activity
- Echocardiogram, an ultrasound that shows your heart’s structure, pumping strength, and valves
- Stress testing to see how your heart performs during exercise
- Heart rhythm monitoring with a wearable monitor for palpitations or fainting
- Blood work for cholesterol, blood sugar, and other markers
- Coronary CT or calcium scoring to look for plaque in the heart arteries
Bring a list of your medications, any recent test results, and notes on when your symptoms happen.
Frequently Asked Questions
Do I need a referral to see a cardiologist? It depends on your insurance. Many PPO plans let you book directly, while HMO plans usually need a referral from your primary care doctor. Check with your plan, your primary care provider, or call our office for help.
At what age should I see a cardiologist? There’s no set age. See a cardiologist at any age if you have symptoms. Consider a preventive evaluation if you have risk factors like diabetes, high blood pressure, high cholesterol, or a family history of early heart disease, especially after age 40.
Are heart palpitations dangerous? Most palpitations are harmless and are triggered by caffeine, stress, dehydration, or lack of sleep. See a cardiologist if they’re frequent, last more than a few minutes, or come with chest pain, dizziness, shortness of breath, or fainting.
Can heart disease be present without symptoms? Yes. High blood pressure, high cholesterol, and early coronary artery disease often cause no symptoms. That’s why screening matters if you have risk factors.
What’s the difference between a cardiologist and an interventional cardiologist? A cardiologist diagnoses and treats heart conditions with testing, medication, and lifestyle care. An interventional cardiologist is also trained in catheter-based procedures, such as placing stents to open blocked arteries.

Hidden Ways High Blood Pressure Damages Your Body
High blood pressure—also known as hypertension—is one of the most common and dangerous cardiovascular conditions worldwide. Often called the “silent killer,” high blood pressure may not cause noticeable symptoms for years while quietly damaging vital organs.
If left untreated, hypertension can significantly increase the risk of heart attack, stroke, kidney disease, and other life-threatening complications. Understanding how high blood pressure affects the body can help patients take early action to protect their long-term health.
What Is High Blood Pressure?
Blood pressure measures the force of blood pushing against artery walls. When this pressure remains consistently elevated, it places strain on blood vessels and organs throughout the body.
A normal blood pressure reading is generally considered below 120/80 mm Hg. Persistent readings above recommended levels may indicate hypertension and warrant medical evaluation.
How High Blood Pressure Affects the Heart
The heart is one of the primary organs affected by hypertension
1. Thickening of the Heart Muscle
High blood pressure forces the heart to work harder to pump blood. Over time, this increased workload causes the heart muscle—particularly the left ventricle—to thicken, a condition known as left ventricular hypertrophy. This thickening reduces efficiency and may lead to heart failure.
2. Coronary Artery Disease
Hypertension damages the lining of arteries, making them more susceptible to plaque buildup. This process narrows coronary arteries and increases the risk of chest pain (angina) and heart attack.
3. Congestive Heart Failure
When the heart becomes weakened or stiff from prolonged strain, it may lose its ability to pump blood effectively, leading to congestive heart failure.
4. Irregular Heart Rhythms
Structural changes caused by hypertension can increase the risk of arrhythmias such as atrial fibrillation.
How High Blood Pressure Affects the Brain
Hypertension is one of the leading risk factors for stroke and cognitive decline.
1. Stroke Risk
High blood pressure can cause arteries in the brain to narrow or rupture, leading to ischemic or hemorrhagic stroke.
2. Mini-Strokes (TIAs)
Transient ischemic attacks are temporary interruptions of blood flow to the brain and may signal future stroke risk.
3. Vascular Dementia
Chronic hypertension can damage small blood vessels in the brain, contributing to memory loss and cognitive decline.
How High Blood Pressure Affects the Kidneys
High blood pressure can constrict and narrow the blood vessels in your kidneys, which reduces blood flow and stops the kidneys from working well. When this happens, the kidneys are not able to remove all wastes and extra fluid from your body. Extra fluid in the blood vessels can raise your blood pressure even more, creating a dangerous cycle, and cause more damage leading to kidney failure.
- More than 1 in 7 adults in the US, or about 37 million people, may have chronic kidney disease (CKD)
- High blood pressure is the second leading cause of kidney failure in the US after diabetes
- Approximately 1 in 5 adults (20%) in the US with high blood pressure may have CKD
How High Blood Pressure Affects Blood Vessels
Persistent high pressure causes arteries to become stiff and narrowed. This process reduces circulation and increases the risk of:
- Peripheral artery disease
- Aortic aneurysm
- Erectile dysfunction
Poor wound healing
Symptoms of High Blood Pressure
Most people with hypertension do not experience symptoms. However, severely elevated blood pressure may cause:
- Headaches
- Blurred vision
- Chest discomfort
- Shortness of breath
- Nosebleeds
Because symptoms are often absent, routine blood pressure screening is critical.
Blood Pressure Categories
Risk Factors for High Blood Pressure
Several factors increase the likelihood of developing hypertension:
- Family history
- High sodium diet
- Obesity
- Physical inactivity
- Smoking
- Excess alcohol intake
- Diabetes
- Chronic stress
- Aging
How to Prevent and Manage High Blood Pressure
Managing hypertension requires a combination of lifestyle changes and, in some cases, medication therapy.
Follow a Heart-Healthy Diet
Patients are encouraged to:
- Reduce sodium intake
- Increase fruits and vegetables
- Choose whole grains
- Limit processed foods
- Incorporate lean proteins and healthy fats
At least 150 minutes of moderate aerobic exercise weekly can significantly lower blood pressure and improve cardiovascular health.
Maintain A Healthy Weight
Weight reduction can dramatically reduce blood pressure levels.
Chronic stress contributes to blood pressure elevation. Techniques such as meditation, deep breathing, and regular exercise may help.
Avoid Tobacco
Smoking damages blood vessels and accelerates hypertension-related complications.
Take Medications as Prescribed
For many patients, blood pressure medications are necessary to maintain safe levels and prevent organ damage.
The Importance of Preventative Cardiology
Preventative cardiology focuses on early detection and long-term management of cardiovascular risk factors like hypertension. Routine cardiovascular screening helps identify organ damage before symptoms develop.
Diagnostic testing may include:
- Echocardiography
- Stress testing
- Lipid panel testing
- Coronary calcium scoring
- Advanced cardiac imaging
Early intervention significantly reduces the risk of heart attack, stroke, and kidney disease.

The Hidden Dangers of Stress: How It Affects Your Heart
Work deadlines, money worries, caring for a loved one, a health scare: stress is part of life. But when it doesn’t let up, it does more than make you feel tense. Understanding how stress affects your heart can help you protect it. Chronic stress raises blood pressure, inflames arteries and can even trigger a heart attack.
The American Heart Association recognizes that psychological health is closely tied to heart health. Here’s what happens inside your body when you’re stressed, the hidden ways it harms your heart, and what you can do about it.
What Stress Does Inside Your Body
When you face a threat, your brain triggers the “fight or flight” response. Your body releases stress hormones, including adrenaline and cortisol. Your heart beats faster, blood pressure rises, breathing quickens, and blood sugar increases to give you energy.
That response is designed to be short-lived. The problem is that modern stress often doesn’t go away. When the stress response stays switched on for weeks, months or years, it begins to wear down the heart and blood vessels.
7 Hidden Ways Stress Affects Your Heart
1. It Raises Your Blood Pressure
Stress hormones tighten blood vessels and make the heart pump harder. Repeated spikes, along with long-term stress, can contribute to sustained high blood pressure, a leading cause of heart attack and stroke. Learn how high blood pressure damages your body.
2. It Inflames Your Arteries
Research has traced a direct path from the brain to the arteries. In a 2017 study published in The Lancet, people with more activity in the amygdala, the brain’s fear and stress center, had a higher risk of heart attack and stroke. Their brain activity was linked to increased activity in the bone marrow, which produces inflammatory cells, and to more inflammation in their arteries. Inflammation helps plaque grow and become unstable.
3. It Can Trigger a Heart Attack
In people who already have plaque in their arteries, an intense emotional moment, such as an outburst of anger, extreme fear or devastating news, can trigger a heart attack. A sudden surge in heart rate, blood pressure and clotting can cause vulnerable plaque to rupture. Large international studies have found that people under persistent psychological stress have a significantly higher risk of heart attack.
4. It Can Cause “Broken Heart Syndrome”
Takotsubo cardiomyopathy, often called broken heart syndrome, is a sudden weakening of the heart muscle triggered by severe emotional or physical stress, such as the death of a loved one. It causes chest pain and shortness of breath that look exactly like a heart attack. About 90% of cases occur in women, most often after menopause. Most people recover, but it requires emergency care. Learn more in our post on lesser-known heart conditions.
5. It Can Disrupt Your Heart’s Rhythm
Stress hormones make the heart’s electrical system more excitable. This can cause palpitations, skipped beats or a racing heart, and may trigger episodes of atrial fibrillation in people who are prone to it.
6. It Can Reduce Blood Flow to the Heart
In some people with heart disease, mental stress can temporarily reduce blood flow to the heart muscle, even when a standard exercise stress test looks normal. Researchers call this mental stress-induced ischemia. It often causes no symptoms but has been linked to a higher risk of future heart events.
7. It Drives Unhealthy Habits
Stress makes it harder to do the things that protect your heart. People under stress are more likely to sleep poorly, smoke, drink more alcohol, overeat, skip exercise and miss doses of their medications. The AHA notes that depression, in particular, is linked to poor adherence to heart medications.
Warning Signs That Stress Is Affecting Your Heart
Chronic stress often shows up in your body before you recognize it in your mind. Watch for:
- A racing or pounding heartbeat, or palpitations
- Chest tightness or pressure during stressful moments
- Blood pressure readings that are creeping up
- Trouble sleeping or waking up unrested
- Headaches, muscle tension, or stomach upset
- Irritability, anxiety, low mood, or feeling constantly on edge
- Relying more on alcohol, food, or cigarettes to cope
Stress or a heart attack? Anxiety and panic attacks can cause chest discomfort, a racing heart and shortness of breath that feel a lot like a heart attack. Don’t try to tell them apart on your own. Call 911 for new or severe chest pain, chest pain that lasts more than a few minutes, or chest pain with sweating, nausea, fainting or pain spreading to your arm, jaw or back.
Who Is Most at Risk?
Stress affects everyone, but some people face a higher risk of heart effects:
- People who already have heart disease, including those recovering from a heart attack or heart procedure
- Women, who are more likely to experience broken heart syndrome and stress-related reductions in heart blood flow. Read about women’s heart attack symptoms.
- Veterans and others with PTSD, which keeps the stress response persistently activated. See heart disease in veterans.
- Caregivers and people facing financial strain, job insecurity, discrimination or social isolation
- People with depression or anxiety
8 Proven Ways to Lower Stress and Protect Your Heart
You can’t eliminate stress, but you can change how your body responds to it.
- Move every day. Regular physical activity is one of the most effective ways to relieve stress and directly lowers blood pressure. Even a 10-minute walk helps. See our guide to heart-healthy exercises.
- Prioritize sleep. Aim for 7 to 8 hours a night. Keep your bedroom cool, dark and quiet, and avoid alcohol and heavy meals close to bedtime.
- Practice slow breathing. Breathing slowly and deeply, about six breaths a minute, calms the stress response within minutes. Try inhaling for 4 seconds and exhaling for 6.
- Try mindfulness, meditation or yoga. Even 10 to 15 minutes a day can lower perceived stress and may help lower blood pressure.
- Stay connected. Strong relationships buffer the effects of stress. Make time for friends, family and community.
- Limit alcohol and caffeine. Both can worsen anxiety, disrupt sleep and raise blood pressure.
- Set boundaries. Say no when you need to, delegate where you can, and build breaks into your day.
- Get professional help. Counseling, cognitive behavioral therapy and, when needed, medication can effectively treat chronic stress, anxiety and depression. Treating your mind is part of treating your heart.
If you’ve had a heart attack or heart procedure, cardiac rehabilitation combines exercise, education and stress management, and is one of the best ways to recover.
When to See a Doctor
Talk with your doctor or a cardiologist if you have:
- Palpitations, chest discomfort or shortness of breath during stress
- Blood pressure that stays above 130/80
- Stress that’s affecting your sleep, work or relationships
- Heart disease along with depression or anxiety

Frequently Asked Questions
Can stress cause a heart attack? Yes, in people who already have plaque in their arteries. A sudden intense emotion can trigger a heart attack by raising heart rate, blood pressure and clotting. Over the long term, chronic stress also contributes to the high blood pressure and artery inflammation that lead to heart disease.
Can stress cause chest pain without a heart problem? Yes. Stress and anxiety can cause chest tightness from tense chest muscles, rapid breathing or panic attacks. However, chest pain should never be assumed to be “just stress” without a medical evaluation, especially if you have heart risk factors.
Can stress cause high blood pressure? Stress causes temporary spikes in blood pressure. Over time, chronic stress and the habits that come with it, such as poor sleep, alcohol use and inactivity, can contribute to lasting high blood pressure.
Can stress cause heart palpitations? Yes. Stress hormones can cause a racing heart, a pounding sensation or skipped beats. Most stress-related palpitations are harmless, but see a doctor if they’re frequent or come with dizziness, fainting, chest pain or shortness of breath.
Does reducing stress actually help my heart? Yes. Lower stress supports healthier blood pressure, better sleep and healthier habits. Exercise, in particular, reduces stress and lowers heart risk at the same time.

What Is Nuclear Cardiology? Tests, Benefits, and What Patients Should Know
Nuclear cardiology is a specialized field of cardiovascular medicine that uses safe, low-dose radioactive tracers combined with advanced imaging technology to evaluate heart function, blood flow, and structural abnormalities. This advanced diagnostic approach helps cardiologists detect coronary artery disease, assess heart muscle damage, and evaluate overall cardiovascular performance with high accuracy.
Physicians who specialize in nuclear cardiology undergo extensive medical training. After completing undergraduate education, nuclear cardiologists attend medical school at a Liaison Committee on Medical Education (LCME)-accredited institution, followed by internal medicine residency training and a cardiovascular disease fellowship. Additional specialized training in nuclear cardiology is required before physicians can obtain certification through the Certification Board of Nuclear Cardiology (CBNC) and other recognized cardiovascular imaging credentialing organizations.
Nuclear cardiology plays an essential role in modern heart disease diagnosis and prevention. Common nuclear cardiology procedures, such as nuclear stress testing and myocardial perfusion imaging, allow cardiologists to measure blood flow to the heart muscle, evaluate heart function, and identify areas of reduced circulation that may increase the risk of heart attack or other cardiovascular complications.
In this article, we provide an overview of common nuclear cardiology tests and explain how these advanced imaging techniques help diagnose and monitor heart conditions.
If you are looking for a board-certified cardiologist in Tampa Bay specializing in advanced cardiac imaging, Sachin Diwadkar, MD, at Ascent Cardiology offers expert nuclear cardiology services. Dr. Diwadkar holds board certification in nuclear cardiology from both the Council for Certification in Cardiovascular Imaging (CCCVI) and the Certification Board of Nuclear Cardiology (CBNC), providing patients with comprehensive, high-quality cardiovascular diagnostic care.
Myocardial perfusion imaging (MPI), commonly known as a nuclear stress test, is one of the most frequently performed nuclear cardiology procedures used to evaluate blood flow to the heart muscle and assess overall cardiac function. This advanced heart imaging test helps cardiologists diagnose coronary artery disease, identify areas of reduced circulation, and evaluate heart muscle damage following a heart attack.
A nuclear stress test is designed to show how effectively blood flows through the heart during both rest and physical or medication-induced stress. MPI is often recommended for patients experiencing symptoms such as chest pain, shortness of breath, or unexplained fatigue, as well as for patients with known heart disease or elevated cardiovascular risk.
During myocardial perfusion imaging, a small amount of a safe radioactive imaging agent, known as a radioactive tracer, is injected into the bloodstream through an intravenous (IV) line. The tracer allows specialized imaging equipment to capture detailed images of blood flow to different areas of the heart muscle.
The test typically involves two phases:
Resting Scan: Images are taken while the heart is at rest to evaluate baseline blood flow.
Stress Scan: Images are taken after the heart is stressed either through exercise or medication.
Stress can be achieved through physical exercise, such as walking on a treadmill or riding a stationary bicycle. For patients who are unable to exercise, medications such as adenosine or dipyridamole may be used to simulate the effects of exercise by increasing blood flow to the heart.
By comparing images taken during rest and stress, cardiologists can determine which areas of the heart muscle are receiving adequate blood flow. Healthy heart muscle typically absorbs the tracer normally, while areas with reduced tracer uptake may indicate blocked or narrowed coronary arteries, scar tissue from prior heart damage, or areas at increased risk for heart attack.
Myocardial perfusion imaging is a valuable diagnostic tool that helps guide treatment decisions, determine the need for further testing or intervention, and monitor the effectiveness of cardiovascular therapies.
Single-photon emission computed tomography (SPECT) is an advanced nuclear cardiology imaging test used to diagnose and evaluate coronary artery disease and cardiac ischemia (reduced blood flow to the heart muscle). SPECT imaging is commonly performed as part of a nuclear stress test and helps cardiologists assess how well blood is circulating through the heart during rest and stress conditions.
Similar to myocardial perfusion imaging (MPI), the SPECT test begins with the injection of a small amount of a safe radioactive tracer into the bloodstream. This tracer emits gamma rays that are detected by specialized imaging equipment, including a gamma camera and, in many cases, an integrated CT scanner. These technologies work together to produce detailed, three-dimensional images that allow cardiologists to evaluate blood flow patterns and heart muscle function.
SPECT imaging helps identify areas of the heart receiving adequate blood supply, as well as areas affected by blocked or narrowed coronary arteries, scar tissue from prior heart attacks, or regions at risk for future cardiac events.
Cardiac positron emission tomography combined with computed tomography (PET-CT) is another highly advanced nuclear cardiology imaging technique that provides additional diagnostic information beyond traditional SPECT imaging. PET-CT allows cardiologists to obtain highly detailed images of coronary artery structure, measure coronary calcium buildup, and evaluate blood flow to the heart muscle with exceptional accuracy.
PET-CT imaging offers several advantages, including improved image clarity, enhanced detection of coronary artery disease, and precise measurement of myocardial blood flow. These capabilities help cardiologists determine whether patients may benefit from additional procedures such as coronary angiography, stent placement, or other cardiovascular interventions.
Both SPECT and PET-CT imaging are highly effective tools for diagnosing coronary artery disease, evaluating blood supply to damaged areas of the heart, and guiding personalized treatment plans designed to improve long-term cardiovascular outcomes.
What do nuclear cardiology procedures have in common? These advanced diagnostic tests are minimally invasive, highly accurate, and essential tools for the early detection and prevention of heart disease. Nuclear cardiology imaging techniques, including nuclear stress testing, SPECT imaging, and PET-CT cardiac scans, help cardiologists evaluate blood flow to the heart muscle, assess heart function, and identify areas of previous or ongoing heart damage.
Determining how well your heart performs under stress through nuclear stress testing is an important step in diagnosing coronary artery disease and developing an effective, personalized treatment plan. These advanced imaging tests allow cardiologists to detect cardiovascular problems early, often before symptoms become severe, improving long-term heart health outcomes. That’s why, it’s time to consult with a board-certified cardiologist in Tampa, FL, equipped with years of experience in nuclear cardiology.
Patients seeking advanced nuclear cardiology testing and preventative heart care in Tampa, Florida, can trust the experience and expertise of Sachin Diwadkar, MD, at Ascent Cardiology. Dr. Diwadkar is board certified in nuclear cardiology and has extensive experience using advanced cardiac imaging techniques to diagnose and manage coronary artery disease and other cardiovascular conditions.

Coronary Artery Disease: 10 Warning Signs You Should Never Ignore
Coronary artery disease (CAD) is the most common form of heart disease and the main cause of heart attacks. Yet its warning signs are often subtle, easy to explain away, or missing entirely until a heart attack strikes. Knowing the coronary artery disease warning signs, and acting on them early, can save your heart muscle and your life.
According to the American Heart Association’s 2025 statistics, cardiovascular disease remains the leading cause of death in the United States, and coronary heart disease accounts for about 40% of those deaths.
Coronary artery disease develops when cholesterol-rich plaque builds up inside the arteries that supply blood to the heart muscle, a process called atherosclerosis. Over years, plaque can narrow the arteries and limit blood flow, especially when the heart needs more oxygen, such as during exercise or stress.
Plaque can also crack or rupture. A blood clot then forms on top of it and can suddenly block the artery, causing a heart attack. That is why some people have no warning at all before a heart attack.
Why Coronary Artery Disease Warning Signs Are Often Missed
The National Heart, Lung, and Blood Institute notes that coronary heart disease may cause no symptoms until a heart attack or other complication occurs. When symptoms do appear, they are often mistaken for indigestion, a pulled muscle, aging, stress or being out of shape. Women, older adults and people with diabetes are especially likely to have atypical symptoms.
10 Coronary Artery Disease Warning Signs You Should Never Ignore
1. Chest Pressure or Discomfort With Activity (Angina)
The classic sign of coronary artery disease is angina: pressure, squeezing, tightness, heaviness or burning in the chest. It often comes on with exertion, such as climbing stairs or walking briskly, or with emotional stress, and eases with rest. Many people don’t describe it as “pain” at all.
2. Pain That Spreads to the Arm, Shoulder, Neck, Jaw or Back
Heart-related discomfort can spread, or show up only in these areas. The NHLBI notes that angina may spread to the shoulders, arms, neck, jaw or back. Jaw or arm discomfort that comes with activity and goes away with rest deserves attention.
3. Shortness of Breath
Breathlessness during activities you used to handle easily can be the main or only sign of reduced blood flow to the heart, especially in women, older adults and people with diabetes.
4. Unusual Fatigue
Extreme or unexplained tiredness, especially if it’s new and limits your normal activities, can be an early sign. The NHLBI notes that women more often report extreme tiredness during a heart attack.
5. Indigestion, Nausea or Upper Stomach Discomfort
Heart symptoms can feel like heartburn or an upset stomach. Be suspicious if “indigestion” comes on with exertion, doesn’t respond to antacids, or comes with breathlessness or sweating.
6. Cold Sweats
Breaking into a cold sweat without a clear reason, particularly with chest discomfort or breathlessness, is a warning sign of a heart attack.
7. Dizziness, Lightheadedness or Fainting
Feeling faint or passing out can signal reduced blood flow or a dangerous heart rhythm triggered by a blocked artery. Fainting during exertion always needs prompt evaluation.
8. Symptoms That Come With Less Effort or at Rest
A change in pattern is a red flag. If chest discomfort now comes on with less activity, lasts longer, or happens at rest, it may be unstable angina, a warning that a heart attack may be near. This needs same-day medical attention or a 911 call.
9. Leg Pain When Walking
Cramping or aching in the calves, thighs or buttocks that comes on with walking and eases with rest may be peripheral artery disease. Plaque in the legs often means plaque in the heart arteries too. Read more about poor circulation in your legs.
10. Erectile Dysfunction
In men, erectile dysfunction can be an early sign of artery disease, because the small arteries involved may narrow before the larger heart arteries. New erectile dysfunction, especially with other risk factors, is a good reason for a heart risk check. See testosterone and heart disease.
The Silent Threat: No Symptoms at All
Some people have no symptoms until a heart attack. Others have a “silent” heart attack and never know it. According to the American Heart Association’s Go Red for Women, a silent heart attack may cause no symptoms, minimal symptoms, or symptoms that feel like indigestion, the flu or a strained chest muscle. It may only be discovered later on an ECG or imaging test. That is why knowing your risk factors matters as much as knowing the symptoms. Women can read more in heart disease in women: 10 warning signs.
Call 911 or Call Your Doctor? Know the Difference
| Situation | What it may mean | What to do |
|---|---|---|
| Chest pressure or pain lasting more than a few minutes, or at rest | Possible heart attack or unstable angina | Call 911 now |
| Chest discomfort with sweating, nausea, breathlessness or fainting | Possible heart attack | Call 911 now |
| Angina that is new, more frequent, or comes with less effort | Unstable angina, high risk of heart attack | Call 911 or seek same-day emergency care |
| Chest discomfort with exertion that goes away with rest, same pattern for weeks | Stable angina | See a cardiologist promptly, within days |
| Gradually worsening breathlessness or fatigue with activity | Possible coronary artery disease or heart failure | Schedule a cardiology evaluation |
| Leg pain with walking or new erectile dysfunction | Possible artery disease elsewhere in the body | Ask for a heart and vascular risk check |
The NHLBI’s advice is simple: if you can’t tell whether your chest pain is a heart attack, call 911 right away. Don’t drive yourself to the hospital. Paramedics can begin treatment on the way. Learn more about cardiac emergencies you should never ignore.
Are You at Risk for Coronary Artery Disease?
Warning signs matter more when you have risk factors. The major ones include:
- High blood pressure
- High LDL cholesterol or high lipoprotein(a)
- Diabetes or prediabetes
- Smoking or vaping
- A family history of early heart disease (father or brother before 55, mother or sister before 65)
- Overweight, especially around the waist
- Physical inactivity
- Chronic kidney disease
- Autoimmune conditions such as lupus, rheumatoid arthritis and psoriasis (see autoimmune disease and heart disease)
- Pregnancy complications such as preeclampsia, and early menopause
How Coronary Artery Disease Is Diagnosed
Depending on your symptoms and risk, your cardiologist may recommend:
- ECG: checks the heart’s electrical activity and signs of a prior heart attack
- Stress test: shows how the heart responds to exercise, with or without imaging
- Echocardiogram: an ultrasound of the heart’s pumping and valves
- Coronary artery calcium (CAC) score: a quick CT scan that measures calcified plaque
- Coronary CT angiography: a detailed CT image of the heart arteries
- Cardiac catheterization: an X-ray dye test that shows blockages directly and allows treatment during the same procedure
Treatment Options
Most people with coronary artery disease are treated with lifestyle changes and medications that lower cholesterol, control blood pressure, prevent clots and relieve angina. When blockages cause persistent symptoms or a heart attack, an interventional cardiologist may open the artery with a stent, or bypass surgery may be recommended. Read the truth about coronary stents and the truth about heart medications.
Coronary Artery Disease FAQ
What is the first sign of coronary artery disease? For many people, it is chest pressure or tightness during exertion that eases with rest. For others, the first sign is shortness of breath, unusual fatigue, or, unfortunately, a heart attack.
Can you have coronary artery disease with a normal ECG? Yes. A resting ECG is often normal between episodes. Stress testing, a calcium score or coronary CT angiography may be needed to find the disease.
Are coronary artery disease symptoms different in women? They can be. Women are somewhat less likely to have chest pain during a heart attack and more likely to report breathlessness, extreme fatigue, nausea or stomach discomfort.
Can coronary artery disease be reversed? Plaque can stabilize and, in some cases, shrink modestly with intensive cholesterol lowering and healthy habits. Treatment greatly lowers the risk of heart attack even when plaque remains.
Who should be screened for coronary artery disease? Adults with risk factors such as high blood pressure, high cholesterol, diabetes, smoking or a family history should talk with their doctor about their 10-year risk. A coronary calcium score can help clarify risk for many people.

5 Reasons to Get a Cardiac CT Scan for Heart Disease Detection
5 Reasons to Get a Cardiac CT
Heart disease remains one of the leading causes of death in the United States, often developing silently before symptoms appear. Fortunately, advances in cardiac imaging technology allow cardiologists to detect cardiovascular disease earlier than ever before. One of the most effective noninvasive diagnostic tools available today is the cardiac CT scan, also known as coronary CT angiography or CT coronary calcium scoring.
A cardiac CT scan uses advanced computed tomography imaging with minimal radiation to create detailed images of the heart and coronary arteries. These scans help cardiologists identify plaque buildup, evaluate blood flow, and assess overall cardiovascular risk.
For patients living in Tampa and the surrounding Tampa Bay area, early detection through advanced cardiac imaging can play a critical role in preventing heart attacks and other serious complications. Below are five important reasons your cardiologist may recommend a cardiac CT scan.
1. Early detection of Coronary Artery Disease
One of the primary benefits of a cardiac CT scan is its ability to detect coronary artery disease (CAD) before symptoms develop. Coronary artery disease occurs when plaque—made up of cholesterol, calcium, and inflammatory cells—builds up inside coronary arteries and restricts blood flow to the heart muscle.
Because coronary artery disease often progresses silently, many individuals do not experience symptoms until a blockage becomes severe or a heart attack occurs. A cardiac CT scan can identify plaque buildup at early stages, allowing cardiologists to recommend preventative treatments before serious cardiovascular complications develop.
Early detection is especially important for individuals with risk factors such as:
- Family history of heart disease
- High blood pressure
- High cholesterol
- Diabetes
- Smoking history
- Obesity
- Sedentary lifestyle
2. Measurement of Coronary Calcium Score
A cardiac CT scan can measure the coronary artery calcium score, which is an important indicator of plaque buildup inside coronary arteries. The calcium score helps cardiologists estimate a patient’s future risk of heart attack and cardiovascular events.
Higher calcium scores generally indicate a greater amount of plaque and increased cardiovascular risk. Conversely, a low or zero calcium score may suggest a lower risk of significant coronary artery disease.
Coronary calcium scoring is especially useful for patients who may not have symptoms but have moderate cardiovascular risk factors. The results can help guide decisions regarding cholesterol management, medication therapy, and lifestyle changes aimed at reducing long-term cardiovascular risk.
3. Detailed Noninvasive Evaluation of Coronary Arteries
Unlike traditional cardiac catheterization, which requires inserting a catheter into blood vessels, cardiac CT scans are completely noninvasive. The test uses advanced imaging technology and contrast dye to visualize coronary arteries without the need for surgical intervention.
During a cardiac CT scan, patients lie on a scanning table that moves through the CT scanner while images of the heart are captured. The procedure is typically quick, painless, and requires minimal recovery time.
Noninvasive cardiac CT imaging allows cardiologists to evaluate:
Coronary artery narrowing or blockages
Plaque characteristics and stability
Heart chamber structure
Blood vessel anatomy
Potential congenital abnormalities
Because of its safety and convenience, cardiac CT scanning is increasingly used as a frontline diagnostic test for evaluating cardiovascular risk.
4. Personalized Treatment Planning
Cardiac CT scans provide detailed information that allows cardiologists to develop personalized cardiovascular treatment plans. By identifying the location and severity of plaque buildup, physicians can determine whether patients would benefit from lifestyle modifications, medication therapy, or additional diagnostic testing.
For example, cardiac CT results may help guide decisions regarding:
Cholesterol-lowering medications
Blood pressure management
Antiplatelet therapy
Stress testing or further cardiac imaging
Need for invasive procedures such as angiography or stent placement
Personalized treatment strategies based on cardiac CT imaging help improve patient outcomes and reduce unnecessary procedures.
5. Prevention of Future Cardiac Events
Perhaps the most important benefit of cardiac CT scanning is its role in preventing heart attacks and other cardiovascular emergencies. By detecting heart disease early and identifying high-risk plaque patterns, cardiologists can implement preventative treatment strategies before serious complications occur.
Preventative cardiology focuses on reducing cardiovascular risk through early diagnosis, lifestyle intervention, and evidence-based medical therapy. Cardiac CT imaging plays a vital role in helping patients understand their heart health and take proactive steps to reduce future risk.
Who Should Consider a Cardiac CT Scan?
A cardiac CT scan may be recommended for individuals who:
-
Have intermediate risk for coronary artery disease
-
Have abnormal stress test results
-
Experience unexplained chest discomfort
-
Have strong family history of heart disease
-
Want comprehensive cardiovascular risk evaluation
-
Have multiple cardiovascular risk factors
A consultation with a cardiologist can help determine whether cardiac CT imaging is appropriate based on individual medical history and risk profile.

At Ascent Cardiology, patients receive comprehensive heart disease screening using advanced diagnostic imaging technologies. Cardiac CT scans help identify coronary artery disease early and guide personalized treatment strategies designed to improve long-term cardiovascular outcomes.
What to Expect During a Cardiac CT
Cardiac CT scans are typically completed in less than 30 minutes. During the procedure:
-
Electrodes may be placed on the chest to monitor heart rhythm.
-
Contrast dye may be administered through an IV to enhance imaging.
-
Patients lie comfortably while the CT scanner captures detailed images.
-
Most patients can resume normal activities immediately after testing.
The procedure is safe, fast, and highly accurate in detecting coronary artery disease.
Schedule a Cardiac CT Consultation
Early detection remains one of the most effective ways to prevent heart disease and improve long-term cardiovascular health.

Does Heart Disease Increase Risk From COVID-19? What Patients Should Know
COVID-19 has affected millions of people worldwide, and research has shown that individuals with underlying health conditions may face a higher risk of severe illness. Among these conditions, heart disease remains one of the most significant risk factors for complications related to COVID-19. Understanding the connection between cardiovascular disease and COVID-19 can help patients take proactive steps to protect their heart health and overall well-being.
How COVID-19 Affects the Cardiovascular System
COVID-19 is primarily a respiratory illness, but the virus can also affect the heart and blood vessels. Studies have shown that COVID-19 can trigger inflammation throughout the body, which may place additional strain on the cardiovascular system.
The virus may contribute to several heart-related complications, including:
Increased inflammation of the heart muscle (myocarditis)
Worsening heart failure symptoms
Increased risk of abnormal heart rhythms (arrhythmias)
Blood clot formation that can lead to heart attack or stroke
Increased stress on the heart due to reduced oxygen levels
For individuals with pre-existing cardiovascular disease, these complications may significantly increase the risk of severe illness and hospitalization.
Related: Staying Active With Heart Disease
Why Patients With Heart Disease May Be at Higher Risk
Patients with underlying cardiovascular conditions often have reduced heart function or narrowed coronary arteries, which can make it more difficult for the body to respond to infection and inflammation. COVID-19 can worsen existing cardiovascular problems by increasing metabolic demand, reducing oxygen delivery, and triggering inflammatory responses.
Certain heart conditions associated with higher COVID-19 risk include:
Coronary artery disease
Heart failure
Hypertension (high blood pressure)
Cardiomyopathy
History of heart attack
Peripheral artery disease
Congenital heart disease
Individuals with multiple cardiovascular risk factors—such as diabetes, obesity, or smoking history—may face an even greater risk of complications.
Symptoms of COVID-19 That May Affect Heart Patients
COVID-19 symptoms vary widely and can range from mild illness to severe respiratory and cardiovascular complications. Heart disease patients should be particularly aware of symptoms such as:
Chest discomfort or pressure
Shortness of breath
Fatigue or weakness
Rapid or irregular heartbeat
Dizziness or fainting
Swelling in the legs or abdomen
Because some of these symptoms overlap with cardiovascular conditions, it is important for patients to consult a healthcare provider if new or worsening symptoms occur.
Can COVID-19 Cause Long-Term Heart Problems?
Emerging research suggests that COVID-19 may cause long-term cardiovascular complications in some patients. Post-COVID heart issues may include persistent inflammation, reduced heart function, and increased risk of blood clotting disorders.
Patients who have recovered from COVID-19 but continue to experience chest discomfort, fatigue, or shortness of breath may benefit from cardiovascular screening and evaluation by a cardiologist.
Schedule a Cardiovascular Evaluation
Patients with heart disease or cardiovascular risk factors should consider scheduling a heart health evaluation, particularly if they have experienced COVID-19 infection or lingering symptoms.
Patients in Tampa Bay can schedule a consultation with our cardiologists at Ascent Cardiology to receive comprehensive cardiovascular screening and personalized heart health guidance.

Cardiac Stress Tests: What They Are, Types, and What to Expect
What is a Stress Test?
A cardiac stress test measures how well your heart functions while it is working harder than usual. During physical exertion or medication-induced stress, the heart requires more oxygen-rich blood. If coronary arteries are narrowed or blocked, reduced blood flow may be detected during stress testing.
Stress testing allows cardiologists to evaluate:
Blood flow to the heart muscle
Heart rhythm and electrical activity
Exercise tolerance and cardiovascular fitness
Heart valve and pumping function
Presence of coronary artery disease
Types of Stress Tests
There are several types of cardiac stress tests, each providing unique information about heart health.
Exercise Treadmill Stress Test
The most common stress test involves walking on a treadmill or riding a stationary bicycle while heart rate, blood pressure, and electrocardiogram (ECG) activity are monitored. Exercise intensity gradually increases to evaluate heart performance under stress.
This test is commonly used to assess symptoms such as chest pain, shortness of breath, and exercise intolerance.
Stress Echocardiogram
A stress echocardiogram combines ultrasound imaging with exercise or medication-induced stress. This test evaluates heart muscle movement, valve function, and pumping efficiency before and after stress.
Stress echocardiography helps detect areas of reduced blood flow and assess structural heart abnormalities.
Nuclear Stress Test
A nuclear stress test uses a small amount of radioactive tracer and advanced imaging technology to evaluate blood flow to the heart muscle. Images are taken at rest and during stress to identify areas of decreased circulation.
Nuclear stress testing provides highly detailed information and is often recommended for patients with higher cardiovascular risk or unclear exercise stress test results.
Pharmacologic Stress Test
For patients unable to exercise due to physical limitations or medical conditions, medications may be used to simulate the effects of exercise by increasing blood flow to the heart. Pharmacologic stress testing is often combined with echocardiography or nuclear imaging.
Who Should Consider a Cardiac Stress Test?
Cardiac stress testing may be recommended for individuals who:
Experience chest discomfort or shortness of breath
Have abnormal ECG results
Have risk factors for coronary artery disease
Have known heart disease requiring monitoring
Need cardiovascular clearance before surgery
Want comprehensive heart health evaluation
Patients with risk factors such as high blood pressure, diabetes, high cholesterol, smoking history, obesity, or family history of heart disease may benefit from stress testing.
Are Cardiac Stress Tests Safe?
Cardiac stress testing is generally very safe and well-tolerated. Complications are rare and testing is performed under close medical supervision. Cardiologists evaluate each patient’s medical history to ensure the most appropriate type of stress test is performed.
Schedule a Cardiac Stress Test Consultation
Cardiac stress testing plays an essential role in diagnosing heart disease and preventing future cardiovascular events. Patients concerned about heart health or experiencing symptoms should consider scheduling a stress test evaluation.

How Cardiovascular Health May Help Prevent Cognitive Decline
Recent research published in the Journal of the American College of Cardiology suggests that individuals with a higher risk of developing cardiovascular disease may also face an increased risk of cognitive decline and dementia. These findings highlight the important connection between heart health and brain function, suggesting that maintaining strong cardiovascular health may help preserve cognitive performance later in life.
Growing evidence shows that controlling cardiovascular risk factors—such as high blood pressure, high cholesterol, diabetes, obesity, and smoking—may help reduce the risk of memory loss and neurodegenerative conditions. Early prevention and routine cardiovascular screening play an important role in protecting both heart and brain health.
In this article, a Tampa cardiologist from Ascent Cardiology explains the relationship between cardiovascular disease and cognitive decline and reviews practical steps patients can take to improve heart health and reduce long-term neurological risk.
Adopting a heart-healthy diet and lifestyle is one of the most effective ways to reduce the risk of cardiovascular disease and cognitive decline. Research continues to show that maintaining healthy habits supports both long-term heart and brain function. The American Heart Association recommends several evidence-based lifestyle strategies that can help protect cardiovascular wellness and reduce the risk of memory loss and dementia.
Key steps to support heart and brain health include:
Eat a balanced, nutrient-rich diet that includes fruits, vegetables, whole grains, lean proteins, and healthy fats
Limit saturated fats, sodium, red meat, and sugar-sweetened beverages, which can increase cholesterol levels and blood pressure
Moderate alcohol consumption, as excessive alcohol intake may negatively affect cardiovascular and neurological health
Maintain a physically active lifestyle, which helps improve circulation, lower blood pressure, and support cognitive function
Avoid smoking, vaping, and all tobacco products, as tobacco use significantly increases the risk of heart disease, stroke, and cognitive decline
Regular physical activity is an important component of maintaining cardiovascular health and supporting cognitive function. Health experts recommend aiming for at least 150 minutes of moderate-intensity physical activity, 75 minutes of vigorous physical activity, or an equivalent combination of both each week whenever possible. Consistent exercise helps improve circulation, lower blood pressure, control cholesterol levels, and reduce overall cardiovascular disease risk.
Research published by Harvard Health Publishing suggests that regular exercise may also provide significant benefits for brain health. In addition to helping relieve anxiety and depression, structured physical activity programs have been shown to improve cognitive performance in individuals experiencing memory challenges and in those who carry the APOE4 gene variant, which is associated with an increased risk of Alzheimer’s disease.
Engaging in routine physical activity—such as brisk walking, cycling, swimming, or strength training—can help support long-term heart health while potentially reducing the risk of cognitive decline. When combined with routine cardiovascular screening and preventative cardiology care, exercise plays a key role in protecting both heart and brain health over time.
Related: The Dangers of High Cholesterol
High blood pressure (hypertension) is one of the most common and often undiagnosed risk factors for cardiovascular disease, affecting millions of adults across the United States, including many individuals living in Tampa and the surrounding Tampa Bay area. When left uncontrolled, high blood pressure can cause arteries to become stiff and narrowed, placing increased strain on blood vessels and vital organs such as the heart, brain, and kidneys. Although hypertension frequently develops without noticeable symptoms, untreated high blood pressure significantly increases the risk of heart attack, heart failure, stroke, kidney disease, and vascular dementia.
Because high blood pressure often develops silently, routine cardiovascular screening and preventative cardiology care are essential. Individuals living in Tampa, South Tampa, Davis Islands, Hyde Park, Westchase, Carrollwood, Clearwater, and St. Petersburg who have risk factors such as family history of heart disease, diabetes, obesity, or high cholesterol should consider regular blood pressure evaluation by a qualified board certified cardiologist.
While there is no permanent cure for high blood pressure, effective management through lifestyle changes and routine medical care can greatly reduce cardiovascular risk and help protect long-term brain health. Regular blood pressure monitoring is an important first step in identifying concerning changes or trends.
Patients can help control blood pressure and improve overall cardiovascular health by:
-
Managing stress through relaxation techniques and healthy coping strategies
-
Following a heart-healthy diet that is low in sodium and rich in fruits, vegetables, and whole grains
-
Maintaining a healthy weight and participating in regular physical activity
-
Avoiding tobacco products and limiting alcohol consumption
-
Working closely with a healthcare provider to monitor blood pressure and determine if medication therapy is appropriate
At Ascent Cardiology in Tampa, patients receive comprehensive hypertension evaluation, cardiovascular risk assessment, and personalized treatment plans designed to reduce long-term heart and brain health complications. Early detection and management of high blood pressure can significantly improve cardiovascular outcomes and help reduce the risk of cognitive decline.
Related: How High Blood Pressure Affects Your Heart and Body
Managing daily stress can be challenging, and for many people, stress itself becomes a major health concern. While it is impossible to control every stressful situation—such as traffic delays, work pressures, or major life events—it is important to understand how chronic stress and the body’s physiological response can increase the risk of cardiovascular disease and cognitive decline.
During periods of stress, the body releases stress hormones such as cortisol and adrenaline. Over time, elevated levels of these hormones can interfere with sleep, appetite regulation, blood pressure control, and overall cardiovascular function. Chronic stress has been linked to increased inflammation, higher blood pressure, and greater risk of heart disease, stroke, and memory impairment.
Reducing stress and supporting long-term heart and brain health often involves adopting positive coping strategies. Research shows that practices that promote positive thinking and emotional wellness may help reduce inflammation and lower stress hormone levels. For example, laughter has been associated with improved blood vessel function and reduced arterial inflammation. Regular physical activity can also help lower blood pressure, improve circulation, and stimulate the release of endorphins that support both mental and cardiovascular health.
Effective stress management strategies may include meditation, mindfulness exercises, regular exercise, social engagement, hobbies, or recreational sports. Because stress affects each person differently, identifying the combination of techniques that works best for your lifestyle is essential.
