摘要

Cilostazol is a generic drug with antiplatelet and antiproliferative effects. It is unclear whether adding cilostazol to standard dual antiplatelet therapy (aspirin and clopidogrel) after percutaneous coronary intervention reduces restenosis and improves the outcomes. We, therefore, conducted a systematic review and meta-analysis. We systematically searched the Cochrane Library, EMBASE, and MEDLINE databases for randomized controlled trials comparing dual antiplatelet therapy with and without cilostazol after percutaneous coronary intervention. The data were pooled using random-effects models and stratified into short-term (1-month), midterm (1- to 12-month), and long-term (鈮?2-month) follow-up durations. Twelve randomized controlled trials involving 5,655 patients met our inclusion criteria. The addition of cilostazol to dual antiplatelet therapy was not associated with a significant change in target lesion revascularization (TLR) and target vessel revascularization (TVR) at short-term follow-up. However, TLR and TVR were significantly reduced at midterm follow-up (relative risk 0.57, 95%confidence interval 0.39 to 0.84, and relative risk 0.62, 95%confidence interval 0.47 to 0.83, respectively). Data regarding TLR and TVR at long-term follow-up were limited and inconclusive. We did not find a difference in myocardial infarction, mortality, or major bleeding at any follow-up duration. In conclusion, the addition of cilostazol to dual antiplatelet therapy after percutaneous coronary intervention has favorable effects on TLR and TVR at 1 to 12 months, with no differences in adverse outcomes at any follow-up duration.
