目的调查国内药物洗脱支架的急性或亚急性血栓发生率,与金属裸支架相比,评价其安全性。方法收集国内84个心脏介入中心近两年的经皮冠状动脉介入治疗资料和血栓病例,并汇总分析。结果支架术总例数为31412例,其中药物洗脱支架置入术占32.7%,金属裸支架置入术占67.3%。二者的血栓发生率分别为0.77%和0.75%。结论药物洗脱支架的安全性与金属裸支架相似。 Objective To investigate the incidence of acute or subacute thrombosis in domestic drug-eluting stents and to evaluate its safety compared with bare-metal stents. Methods Collecting data and thrombosis cases of percutaneous coronary intervention in 84 heart intervention centers in recent two years in our country and summarizing and analyzing them. Results The total number of stenting was 31412 cases, of which 32.7% were treated with drug-eluting stents and 67.3% with bare-metal stents. The incidence of thrombosis was 0.77% and 0.75% respectively. Conclusion The safety of drug-eluting stents is similar to bare-metal stents.
