chest pain, taking medication alone can be as effective as angioplasty
and drugs combined. Drugs used to treat chest pain include aspirin, statins, and blood pressure medications.
After an average of five years, researchers found the drug group had
been hospitalized slightly less often than the angioplasty group. At the
same time, 211 deaths occurred in the angioplasty group and 202 in the
drug group. The study was reported by researchers to the American
College of Cardiology.
In angioplasty, a small balloon is threaded into arteries supplying the
heart to unblock them. (Angioplasty is still recommended to stop the
