Coronary artery disease (CAD) occurs when fatty deposits called plaque collect in the arteries that supply blood to the heart. This buildup narrows or blocks blood vessels, making it harder for your heart to function.
CAD is also known as ischemic heart disease because the heart can’t get enough blood, which carries oxygen to your organs. Left untreated, CAD can cause complications such as a heart attack, arrhythmia (irregular heartbeat), or heart failure.
If you receive a CAD diagnosis, our expert team works together with you to develop a personalized treatment plan. We use advanced skills and the latest techniques to address your specific needs and get your heart beating as it should.
CAD doesn’t always cause symptoms. You may experience chest discomfort or pain (angina) as the first sign that something is wrong. Or your first indication of serious heart trouble could be a heart attack.
Without treatment, CAD can lead to other heart issues, such as arrhythmia or heart failure. Early detection is important for effective treatment.
While chest pain is the most common symptom of CAD, the sensation can vary from person to person. You may feel:
Call 911 immediately if you experience chest pain or heart attack symptoms, such as:
Coronary artery disease (CAD) occurs when plaque buildup narrows or blocks the blood vessels (arteries) that carry blood to your heart. As atherosclerosis – or buildup of plaque – progresses, reducing the blood flow to your heart. CAD forces your heart to work harder to pump blood to the rest of your body.
You may be at risk for developing atherosclerosis and CAD due to factors you can't control, such as family history. But you can reduce your risk for plaque buildup and CAD with lifestyle habits that help boost your health and keep your heart strong.
You may be more likely to develop coronary artery disease if you have biological family members with CAD. Other risk factors include:
It's important to maintain a healthy diet and lifestyle habits to reduce your risk of developing heart disease. You may be more likely to develop CAD if you:
Talk to your health care provider if you are concerned about developing coronary heart disease. Together, you can come up with a customized plan to help maintain your heart health as you age.
Your provider will ask about your medical history and symptoms and do a thorough physical exam to diagnose coronary artery disease. Your doctor may recommend a range of tests to confirm a CAD diagnosis or rule out other conditions.
You may undergo several common tests to check your heart, such as:
Your specific treatment depends on your overall health, symptoms, and the severity of your artery blockage. Sometimes, lifestyle changes or medications can control your blood pressure and bring your weight and cholesterol into a healthy range. In other cases, you may need surgery to restore blood flow and heart function.
Your doctor may prescribe certain medications to treat chest pain, help control blood pressure, and lower cholesterol.
You and your doctor can discuss important lifestyle changes that you can make to reduce your risk for CAD and future heart problems. These lifestyle changes may include:
If the blockage in an artery is severe, you may need a procedure or surgery to help your heart work better. Your doctor may recommend:
Cardiac rehab helps you strengthen your heart in a closely monitored environment. Our physical therapists create an exercise plan that is safe and effective, helping you focus on your recovery.
The best prevention for atherosclerosis and coronary artery disease is a healthy body. To keep yourself as healthy as possible, try to:
Limit sugar, alcohol, processed food, and fast food. Focus instead on eating lots of vegetables, fruits, lean protein (such as chicken and fish), whole grains, and healthy fats. Healthy fats include avocados, extra-virgin olive oil, nuts, seeds, and fatty fish.
Add physical activity to your daily life, engaging in moderate exercise at least three days a week. Talk to your doctor about safe exercises before starting if you have health or heart problems.
Keeping a healthy weight helps your body and organs work at their best. Aim for a body mass index (BMI) under 25.
Smoking, vaping, and using smokeless tobacco products cause your blood vessels to harden, encouraging plaque to form. People exposed to secondhand smoke are also at an increased risk for CAD.
Chronic stress and lack of sleep drive inflammation in the body, increasing the risk of heart disease. Actively work to lessen stress by spending time in nature, taking walks, journaling, or performing other activities that relax you. Aim for seven to eight hours of sleep every night.
