Comparison of clopidogrel versus ticlopidine for prevention of minor myocardial injury after elective coronary stenting

We searched a randomized, double-blinded, prospective study that compared the effectiveness of clopidogrel versus ticlopidine for prevention of minor myocardial injury (MMI) and major clinical events (MCEs) after elective coronary stenting. A total of 158 consecutive patients (98 male, 60 female patients with a mean age of 59.3±5.4 years) were divided into two arms based on treatment with thienopyridines: group I, clopidogrel 1×300 mg as a loading dose, and 1×75 mg per day thereafter, group II, ticlopidine 2×250 mg daily. Both thienopyridines were started on the same day as stent placement. Cardiac troponin T (cTnT) was measured immediately before and 12 h after the procedures. All patients were followed-up during the hospital stay (6±2 days) with respect to MMI and MCEs. The increase frequency and the amount of cTnT level in group I was found significantly lower compared with group II (5 vs.15; P
