美国华盛顿医院心脏病学中心Waksman等研究发现,血栓形成仍然是药物洗脱支架的主要问题,而支架类型与血栓发生率有关,西罗莫司洗脱支架血栓发生率高于紫杉醇支架。与以往研究不同,作者无选择的连续入选1925例冠心病患者进入西罗莫司支架(SES,Cypher)组,844例进入紫杉醇支架(PES Waksman et al. (Washington, DC, Cardiology Center, Washington, DC) found that thrombus formation remains a major issue with drug-eluting stents, which is associated with a higher incidence of thrombosis and a higher incidence of thrombolysis with sirolimus-eluting stents than with paclitaxel. Unlike previous studies, the authors chose 1925 consecutive patients with coronary artery disease to enter the sirolimus-eluting group (SES) group and 844 into the paclitaxel-eluting stent group (PES)
