冠脉支架植入术已在临床广泛应用，但是支架引起的栓塞，甚至死亡不断增加。阿司匹林联用噻氯匹定是降低血栓危险的经典方案，但噻氯匹定存在严重的不良反应。西洛他唑能选择性地抑制磷酸二酯酶，为高效抗血小板剂。本文对照研究西洛他唑用于降低支架植入后的血栓发生率的疗效 Coronary stent implantation has been widely used clinically, but stent-induced embolism, and even death continue to increase. Aspirin plus ticlopidine is a classic regimen to reduce the risk of thrombosis, but ticlopidine has serious adverse reactions. Cilostazol selectively inhibits phosphodiesterase, a highly potent antiplatelet agent. This article controlled the study of cilostazol used to reduce the incidence of thrombosis after stent implantation
