Coronary angioplasty is a procedure that opens a blocked or narrowed artery that leads to the heart. A stent is inserted permanently into the artery to help hold the artery open and restore normal blood flow to the heart.
After an angioplasty, a blood clot could form in the stent after the procedure. This could cause a stroke or heart attack. Physicians often prescribe anti-clotting medication, Warfarin (Coumadin)/Plavix (clopidogrel), after an angioplasty to combat that risk.
Many patients must take this medication for up to a year or more.
