How does angina affect the body?

Angina causes pain in the chest, arms, and back. The pain may be severe, or it may feel like pressure, an ache, or fullness in the chest. Angina is a sign that blood flow to the heart has lessened, and unstable angina can be a sign that a heart attack may be imminent.

A rare type of angina known as variant angina is actually caused by a coronary artery spasm, which causes the artery to narrow. This can be of short or long duration, but is more dangerous the longer it lasts. If the heart does not receive enough blood flow, you may have a heart attack.
