Angina, or angina pectoris, is the discomfort or pain that occurs when the blood supply to the heart muscle is decreased due to the narrowing of a coronary artery. People describe angina as discomfort, pressure, or pain in the chest, back, neck, shoulders, arms (especially the left arm), or jaw. These symptoms most often happen with increased activity or emotional stress.

Angina is a sign that the heart muscle isn’t getting the oxygen it needs. It doesn’t cause permanent damage to the heart, but it can be a warning of a heart attack. So even though some people experience angina for many years without ever having a heart attack, angina pain should be taken seriously.
