Following intracoronary stenting, antiplatelet therapy lead to greater protection from thrombotic complication. A few data are available about the effect of clopidogrel versus cilostazol, an antiplatelet commonly used after intracoronary stenting. To evaluate the efficacy and safety of clopidogrel plus aspirin compared with those of cilostazol plus aspirin in coronary stenting and to evaluate the efficacy of clopidogrel loading dose prior to coronary stenting in clopidogrel group. Data were retrospectively collected from medical charts of patients who had undergone coronary stenting and received either clopidogrel with or without loading 300 mg followed by 75 mg/d (n=58), or 200 mg/d cilostazol (n=72) for 1 year, between January 2000 and May 2002. All patients in both groups received aspirin 200 mg/d throughout the study. The primary endpoints at 7, 30, 180 and 365 days after stenting were the composite of death, Myocardial Infarction, stroke, angina, and revascularization in the intent to treat population and restenosis at follow up angiography. The secondary endpoints were the incidence of bleeding complications at 7, 30, and 365 days, and durg adverse effects at 365 days after stenting. At 180 and 365 days after stenting, the combined primary endpoints were significantly reduced in clopidogrel plus aspirin group (relative risk 0.39; 95% Cl 0.17 to 0.92; p=0.021, RR 0.43; 95% Cl 0.22 to 0.84; p=0.0085, respectively). However, the combined primary endpoints were not significantly different between the two groups at 7 and 30 days (p=1.00, p=0.79, respectively). Angiographic restenosis rate was 14.3% in clopidogrel plus aspirin group and 32.1% in cilostazol plus aspirin group (p=0.19). 300 mg of clopidogrel loading dose did not significantly reduce the combined primary endpoints at 30 days after stenting (RR 0.14; 95% Cl 0.01 to 2.65; p=0.23). The rate of bleeding complications and drug adverse effects were not different between the two groups. In patients undergoing intracoronary stenting, clopidogrel plus aspirin therapy is more beneficial than cilostazol plus aspirin in reducing major adverse cardiac events with similar rate of bleeding complication. A loading dose of clopidogrel did not lead to a statistically significant reduction in major adverse cardiac events.
