Angina is a pain that comes from the heart. It is usually caused by narrowing of the coronary (heart) arteries. Usual treatment includes a statin medicine to lower your cholesterol level, low-dose aspirin to help prevent a heart attack, and a beta-blocker medicine to help protect the heart and to prevent angina pains. An angiotensin-converting enzyme (ACE) inhibitor medicine is advised in some cases. Sometimes angioplasty or surgery are options to widen, or to bypass, narrowed arteries.
