Angina: Introduction

Angina is a common type of chest pain that can occur when the heart muscle is not receiving sufficient blood flow and oxygen. Angina is a symptom of some heart diseases, especially atherosclerosis.

Atherosclerosis is the build-up of plaque and inflammation in the arteries of the body, including the arteries that supply blood to the heart muscle (coronary arteries). Atherosclerosis narrows the coronary arteries and lowers the amount of oxygen-rich blood that reaches the heart muscle. Arteries narrowed by atherosclerosis are more likely to develop a blood clot that completely blocks blood flow, resulting in a heart attack.

The chest pain of angina can be mild to severe. The chest pain of angina is different from the chest pain of a heart attack in that angina generally occurs with activity or exertion and goes away with rest and/or medication, such as nitroglycerin. In contrast, the chest pain of a heart attack does not go away with rest or after taking nitroglycerin. To learn more about other important symptoms and complications of angina, refer to symptoms of angina.

Angina can also be a symptom of other types of heart disease, such as aortic valve disease, coronary artery spasm and cardiac arrhythmias, which can all reduce the amount of blood and oxygen that reaches the heart muscle.

Angina can also be a symptom of anemia, in which a low number of red blood cells in the blood reduces the amount of oxygen supplied to the heart muscle.

Risk factors for developing angina are the same risk factors for developing heart disease. These include having high cholesterol, hypertension, diabetes, high cholesterol (hypercholesterolemia, hyperlipidemia), obesity, and a sedentary lifestyle. Other risk factors include being of African-American ancestry, male, drinking excessive amounts of alcohol, having a lot of long-term stress, smoking, and having a family history of heart disease.

People who have high C-protein levels, which increases atherosclerosis, are also at a higher risk for heart disease and angina.

Making a diagnosis of heart disease includes completing a complete medical evaluation and history and physical examination. Tests that may be used to diagnose angina include blood tests, exercise stress testing, EKG, X-Ray, and imaging tests, such as heart scan, ultrasound and echocardiogram. A coronary angiogram may also be performed. A coronary angiogram is an invasive procedure that reveals which coronary arteries are narrowed or blocked.

It is possible that a diagnosis of angina can be missed or delayed because the symptoms can be similar to symptoms of some other diseases and conditions. To learn more about diseases and conditions that can mimic angina, refer to misdiagnosis of angina.

Angina is treated with an individualized treatment plan that best fits the individual case of angina, age, a person's life style and other factors. Treatment involves regular medical monitoring and testing, lifestyle and dietary changes, and may include medications and surgery. For more details about treatment plans, refer to treatment of angina. ...more »

Other possible causes of chest pain, and there are numerous, can range from less life-threatening (e.g. reflux, heartburn, indigestion, GERD, etc.) to the extremely dangerous (e.g. heart attack, heart disorders, lung disorders and many other causes of chest pain). Always seek emergency medical attention for chest pain or other medical conditions similar to chest pain or angina. ...more »

Chest pain, also called angina (an-JY-nuh). When you have angina, you feel pain in your chest, arms, shoulders, or back. You may feel the pain more when your heart works faster, such as when you exercise. The pain may go away when you rest. You also may feel very weak and sweaty. If you do not get it treated, chest pain may happen more often. If diabetes has damaged the heart nerves, you may not feel the chest pain.
