Overview Unstable angina is a condition in which your heart doesn't get enough blood flow and oxygen. It is a prelude to a heart attack. Most people experience a feeling of chest discomfort or shortness of breath. See also:

Slide 4 :

Treatment *Angioplasty is a procedure to open narrowed or blocked blood vessels that supply blood to the heart. *A coronary artery stent is a small, metal mesh tube that opens up (expands) inside a coronary artery. A stent is often placed after angioplasty. It helps prevent the artery from closing up again. A drug-eluting stent has medicine in it that helps prevent the artery from closing. Your doctor may want you to check into the hospital to get some rest and prevent complications.Blood thinners (antiplatelet drugs) are commonly used to treat and prevent unstable angina. Such medicines include aspirin and the prescription drug clopidogrel.
