Glossary A common symptom of coronary heart disease (CHD) is angina. Angina is chest pain or discomfort that occurs if an area of your heart muscle doesn't get enough oxygen-rich blood. Angina may feel like pressure or squeezing in your chest.

- Quick Facts. A coronary artery spasm usually occurs in an artery narrowed by fatty deposits (plaque). The spasm usually occurs very close to the blockage. But spasm can also occur in a normal coronary artery. When a coronary artery spasm occurs, less blood flows to your heart muscle. This causes chest pain (angina) that can feel like heaviness, tightness, burning, and pressure or squeezing under your breastbone. A coronary artery spasm usually occurs at rest or during sleep.

Why do your arm hurts when you're about to have a heart attack? And which arm is it? Left or right? Symptoms are often subtler in women. Nausea, sweating, fatigue, or shortness of breath can join the typical pressure-like chest pain. Other symptoms that can occur with coronary artery disease include: Shortness of breath.

Chest Pain Symptoms & Signs There are many causes of chest pain. A serious form of chest pain is angina, which is a symptom of heart disease and results from inadequate oxygen supply to the heart muscle. Angina can be caused by coronary artery disease or spasm of the coronary arteries. Chest pain can also be due to a heart attack (coronary occlusion), aortic aneurysm dissection, myocarditis, esophageal spasm, esophagitis, rib injury or disease, anxiety, and other important diseases.

Overview If your coronary arteries narrow, they can't supply enough oxygen-rich blood to your heart — especially when it's beating hard, such as during exercise. At first, the decreased blood flow may not cause any coronary artery disease symptoms. Chest pain (angina).

- Angina pectoris is the medical term for pain or other discomfort in the chest that is due to coronary heart disease. The chest pain or discomfort associated with angina occurs when an area of the heart muscle does not receive enough oxygen-rich blood.Coronary heart disease is the most common type of heart disease in adults. As such, angina is a common cardiovascular condition in the United States.ngina develops due to coronary heart disease and an underlying heart problem called myocardial ischemia. This occurs when one or more of the heart’s coronary arteries, the blood vessels that supply blood to the heart muscle, is narrowed or blocked.

Overview Eventually, the decreased blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack. Because coronary artery disease often develops over decades, you might not notice a problem until you have a significant blockage or a heart attack.

Coronary Artery Disease - Coronary Heart Disease “Coronary artery disease is preventable,” agreed Johnny Lee, M.D., president of New York Heart Associates, and an American Heart Association volunteer. “Typical warning signs are chest pain, shortness of breath, palpitations and even fatigue.”. If you feel any of these symptoms, don’t delay — call 9-1-1.

Angina Pectoris When one or more of the coronary arteries becomes partly or totally blocked, your heart does not get enough blood. This is called ischemic heart disease, or coronary artery disease (CAD). It can cause chest pain (angina). Coronary artery bypass surgery can be used to improve blood flow to your heart.

CHEST PAIN (high blood pressure) as a cause of chest pain in both men and women is listed first because it is the single most common cause of chest pain, including coronary artery disease itself. In other words, more people suffer from chest pain due to high blood pressure than those who have chest pain because of obstructive coronary artery disease.

Chest Pain Angina is a pain that comes from the heart. It is usually caused by narrowing of the coronary arteries. This narrowing causes a reduced blood supply to part, or parts, of the heart muscle. The narrowing is caused by fatty patches or plaques (atheroma) which develop within the inside lining of arteries.

Coronary Artery Disease (CAD) Coronary heart disease (CHD) is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis).f the flow of oxygen-rich blood to your heart muscle is reduced or blocked, angina (an-JI-nuh or AN-juh-nuh) or a heart attack can occur. Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. The pain also can occur in your shoulders, arms, neck, jaw, or back.

Coronary Artery Disease (CAD) Cholesterol plaques from atherosclerosis cause the three main kinds of cardiovascular disease: Coronary artery disease-- Stable cholesterol plaques in the heart's arteries can cause no symptoms or can cause chest pain called angina. Sudden cholesterol plaque rupture and clotting causes blocked arteries. When that happens, heart muscle dies. This is a heart attack, also called myocardial infarction. Cerebrovascular disease-- Cholesterol plaque can rupture in one of the brain's arteries. This causes a stroke, leading to permanent brain damage.
