Angina or angina pectoris, meaning squeezing of the chest, is chest pain or discomfort you feel when there is not enough blood flow to your heart muscle. Angina is not a disease, but rather a symptom of coronary artery disease. The lack of oxygen rich blood to the heart is usually a result of narrower coronary arteries due to atherosclerosis. Angina may feel like pressure or a squeezing pain in your chest and usually starts behind the breastbone. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw, or back.
