最近,药物洗脱支架的晚期和远期血栓发生情况越来越受到关注。无保护左主干病变应用药物洗脱支架介入治疗的注册研究数据显示中期疗效安全和可行,但目前尚无其晚期和远期血栓发生率和预测指标的相关研究。现旨在通过一项大规模多中心注册研究,比较临床主要不良心脏事件(MACE)、 Recently, there has been increasing interest in the development of late and long-term thrombosis of drug-eluting stents. Registry data from non-protected left main disease with drug-eluting stent interventions indicate that mid-term efficacy is safe and feasible, but no studies have yet been made of its rates of thrombosis and predictors of late and long-term outcomes. The aim is to pass a large, multicentre registry study to compare clinical major adverse cardiac events (MACE)
