Hidden Ways High Blood Pressure Damages Your Body

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

Exercise Regularly

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.

Manage Stress

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

For a full list of symptoms that deserve a heart evaluation, see the 10 warning signs you should see a cardiologist.

If you’re in crisis or having thoughts of harming yourself, call or text 988 to reach the 988 Suicide & Crisis Lifeline, available 24 hours a day.

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.

Protect Your Heart From the Effects of Stress

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.

Nuclear Stress Test

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.

Cardiac SPECT

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.

Consult With a Cardiologist

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

SituationWhat it may meanWhat to do
Chest pressure or pain lasting more than a few minutes, or at restPossible heart attack or unstable anginaCall 911 now
Chest discomfort with sweating, nausea, breathlessness or faintingPossible heart attackCall 911 now
Angina that is new, more frequent, or comes with less effortUnstable angina, high risk of heart attackCall 911 or seek same-day emergency care
Chest discomfort with exertion that goes away with rest, same pattern for weeksStable anginaSee a cardiologist promptly, within days
Gradually worsening breathlessness or fatigue with activityPossible coronary artery disease or heart failureSchedule a cardiology evaluation
Leg pain with walking or new erectile dysfunctionPossible artery disease elsewhere in the bodyAsk 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.
