What is Angina?

Angina pectoris (Latin for "chest constriction") is the result of a lack of oxygen supply to the heart muscle, due to reduced blood flow around the heart's blood vessels. This lack of oxygen to the heart is known as myocardial ischemia.

Angina pectoris is a common symptom of myocardial ischemia, which people with coronary artery disease are most often affected by. It is caused by stimulation of nerve endings in the heart muscle and its blood vessels.
