Nearly 1.5 million Americans have signs of acute coronary syndromes, which include chest pains. Approximately 785K people in the U.S. will have a heart attack, and 470K will experience another some time afterward.
The Food and Drug Administration has approved a new medication called Effient, it's purpose being to reduce the thrombotic cardiovascular occurrences. Many patients who will use this drug will already have a stent in place to keep an artery open.
However, medications like Effient can increase the risk of internal bleeding. Patients with a history of stomach ulcers or strokes (even "mini-strokes") should not take the drug.
