Angina: Overview

Angina is a disorder of the heart and its blood vessels that is characterized by chronic chest pain. It is usually caused by narrowed arteries from arteriosclerosis (atherosclerosis). Angina needs to be differentiated from heart attack and other causes of chest pain. Stable angina refers to chest pain that does not occur at rest, but can be brought on by exercise, exertion or activity. Unstable angina has chest pain at rest, or is otherwise not yet considered stable angina (e.g. recently diagnosed). Another type is Microvascular Angina.
