总体上植入后第一年的新一代DES的性能优于BMS

近日研究人员系统考察了新一代药物洗脱支架(DES)与裸金属支架(BMS)安全性特征差异。

研究人员对接受经皮冠状动脉介入治疗的患者进行个体患者数据荟萃分析,以比较新一代DES或BMS植入后的结果,主要结局是心源性死亡或心肌梗死的复合终点。

20项随机试验,总计26616例患者数据,平均随访3.2年。由于心肌梗死风险降低(0.79)以及在轻微但非显著的心脏死亡方面的益处(0.89), DES组的主要结局风险较BMS组降低(HR= 0.84),但全因死亡不受影响(DES的HR=0.96),但确定支架血栓形成(0.63),靶血管血运重建(0.55)的风险降低。研究人员观察到与时间相关的治疗效果,DES与BMS治疗后1年相比,主要结局的风险较低,虽然该效应长期维持,但在1年后差异缩小。

研究认为,总体上植入后第一年的新一代DES的性能优于BMS。
