What is angina?
A person with angina has chest pain or chest discomfort, caused by low oxygen delivery to the heart muscle. In most cases, this is caused by coronary artery disease, a narrowing of the arteries that supply oxygenated blood to the heart. The symptoms of angina occur when the supply of oxygen cannot meet the demand.

What are the symptoms of angina?
The most common symptoms of angina include chest pain, chest tightness, or chest heaviness. Other symptoms include nausea, faintness, excessive sweating, breathing difficulty, and arm pain.

How does the doctor treat angina?
Treatment of angina includes medications to reduce chest pain, improve coronary blood flow, and lower blood pressure. Some patients may be candidates for angioplasty or coronary artery bypass surgery.
