The patient has undergone a myocardial infarction, and clear benefit has been
demonstrated in this patient population with angiotension converting-enzyme (ACE)
inhibitors, aspirin, and beta blockers. After stent placement clopidogrel is indicated for at
least 3 months to prevent in-stent thrombosis. Warfarin was commonly prescribed in the
early days of percutaneous revascularization, but increased bleeding complications and
the advent of platelet ADP-receptor blockers have obviated the need for this
medication.

thanks for questions.
