Heart Disease

Heart disease, or coronary artery disease, is the leading cause of death for both men and women in the United States. But healthy lifestyle changes can help you lower your risk. Learn more about heart disease, including symptoms, diagnosis, and treatment options.

What Is Heart Disease?

Heart disease, or coronary artery disease, is the leading cause of death for men and women in the United States.

Many problems with the heart happen because of atherosclerosis, or the buildup of plaque in arteries. Plaque buildup causes your arteries to narrow, which makes it harder for your blood to flow freely through your body.

What are the types of heart disease?

  • Heart attack — When a blood clot cuts off blood flow to part of your heart.
  • Stroke — When a blood vessel to your brain gets blocked, often by a blood clot.
  • Heart failure — When your heart isn't pumping blood as effectively as it used to. Your body doesn't get as much blood and oxygen as it needs.
  • Arrhythmia — When you have an abnormal heart rhythm. It may beat irregularly, too fast, or too slow.
  • Heart valve problems — When a heart valve doesn't open or close properly, affecting how the heart pumps blood through your body.

What causes heart disease?

Causes of heart disease may include:

  • A buildup of plaque over time.
  • Damage to your heart over time from poorly managed chronic conditions or lifestyle factors.
  • A heart-valve birth defect.

What are heart disease risk factors and complications?

Most factors that increase your risk of heart disease relate to lifestyle, such as:

  • High cholesterol.
  • High blood pressure.
  • Smoking.
  • Diabetes.
  • Family history of heart disease.
  • Obesity.
  • Age.

Nearly half of Americans have at least one heart disease risk factor.

How can I prevent heart disease?

Most cases of heart disease, specifically coronary artery disease, are preventable with a healthy lifestyle and medicine.

Some ways to help prevent or delay heart disease include:

  • Managing chronic conditions like diabetes and high blood pressure.
  • Following a healthy diet.
  • Exercising regularly.
  • Quitting smoking and not abusing alcohol.

What Are The Signs And Symptoms Of Heart Disease?

Because heart disease can manifest in different ways, it can be hard to notice symptoms and get a diagnosis.

Not everyone has symptoms of heart disease, and sometimes symptoms can be subtle based on what type of heart disease you have.

Common signs and symptoms include:

  • Heart attack.
  • Chest pain or discomfort (angina).
  • Shortness of breath when active or resting.
  • Fatigue.
  • Swelling in the feet, legs, ankles, or stomach.

If you have arrhythmia, you may feel like your heart is fluttering, beating too fast, or skipping a beat.

Back to top


How Do You Diagnose Heart Disease?

Your doctor will do a physical exam and order tests to diagnose heart disease. He or she will ask about your symptoms, family history, and assess any risk factors.

The UPMC Advanced Cardiac Imaging Program uses state-of-the-art technology not found at other medical centers in the Pittsburgh region.

Tests you may need to help your doctor confirm a heart disease diagnosis include:

  • Electrocardiogram (EKG) — this is a simple, painless test that checks your heart's electrical activity. It looks for heart damage or signs of a prior heart attack.
  • Stress test — during this test, you perform moderate exercise, like walking on a treadmill, to get your heart beating faster. The test checks for shortness of breath andabnormal changes in your heart rate, blood pressure, or heart's rhythm.
  • Blood tests — this test finds heart disease risk factors, such as the cholesterol, sugar, and proteins in your blood.
  • Echocardiogram — this test uses sound waves to take pictures of your heart. It checks blood flow and the size and shape of your heart's valves and chambers.
  • Heart catheterization — this test uses a dye and an x-ray to check how blood flows through your heart and blood vessels. Your doctor will insert the dye into a vein in your arm, groin, or neck using a catheter, or a thin tube.

UPMC's Cardiac Catheterization Program specialists perform more than 23,000 diagnostic and interventional heart catheterizations each year.

How Do You Treat Heart Disease?

Treatment depends on the type of heart disease and how severe.

The goals of heart disease treatment are to:

  • Prevent further heart damage.
  • Slow or stop the buildup of plaque.
  • Lower the risk of blood clots to prevent heart attack and stroke.
  • Relieve symptoms.
  • Widen or bypass arteries.
  • Correct valve problems.

A treatment plan may include lifestyle changes, heart disease drugs, and surgery.

Lifestyle Changes

To prevent or reverse damage to the heart and lessen symptoms, you should adopt some heart-healthy lifestyle habits.

Some lifestyle changes you can make are to:

  • Quit smoking.
  • Avoid excessive drinking.
  • Follow a heart-healthy diet.
  • Exercise regularly.
  • Maintain an ideal weight.
  • Manage stress.

Medicine to treat heart disease

Your doctor may prescribe drugs to lower your risk of serious complications and to manage symptoms.

Heart disease medications help:

  • Lower cholesterol.
  • Lower blood pressure.
  • Prevent blood clots.
  • Decrease the chances of having a heart attack.
  • Lessen your heart's workload.

Surgery for heart disease

You may need surgery to open blocked arteries or to repair or replace a valve.

Methods we use to treat heart disease include:

  • Angioplasty — surgeons thread a catheter through a blood vessel and into a blocked artery. They inflate a balloon at the end of the catheter to compress plaque and allow blood to flow freely through the artery.
  • Coronary bypass surgery — surgeons use blood vessels from other parts of your body to restore blood flow to your heart.
  • Heart valve repair or replacement surgery.
  • Heart surgery — surgeons often use this treatment method to repair a birth defect.

Severe cases of heart failure or birth defects may require a heart transplant.
