2018年1月,发表在《JACC Cardiovasc Interv》的一项由美国、法国、意大利、英国等国科学家进行的分析,考察了增加新一代药物洗脱支架长度对于接受PCI女性的3年临床结局的影响。

目的:研究旨在考察行新一代药物洗脱支架(DES)经皮冠状动脉介入(PCI)的女性中,每例患者的支架长度和每个病变支架长度是否为3年结局的不良标记物。

背景:在先进的支架技术时代,支架长度与临床不良结局相关性尚不清楚。

方法:评价WIN-DES(Women in Innovation and Drug-Eluting Stents)数据库中14项随机试验中接受新一代DES的女性。在四分位数中,分析5403例女性中,每例患者支架的总长(第一四分位数,8~18 mm;第二四分位数,18~24 mm;第三四分位数,24~36 mm;第四四分位数,≥36 mm),以及5232例女性中,每个病变支架长度(第一四分位数,8~18 mm;第二四分位数,18~20 mm;第三四分位数,20~27 mm;第四四分位数,≥27 mm)。首要终点为3年重大不良心血管事件(MACE),定义为全因死亡、心梗或靶病变血运重建的复合终点。

结果:在这项每患者分析中,随着支架长度增加,3年MACE(趋势分析p<0.0001)、心梗(趋势p<0.001)、心源性死亡(趋势分析p=0.038)和靶病变血运重建(趋势分析p=0.011)的校正风险阶梯式升高,但无绝对的/可能的支架内血栓事件(趋势分析p=0.673)。在每病变分析中,3年MACE(趋势分析p=0.002)和心梗(趋势分析p<0.0001)校正风险增加,但其他个体终点风险没有增加。1~3年随访后期生存分析结果显示,每位患者的支架长度与靶病变血运重建(p=0.0131)和MACE(p=0.0499)之间的相关性较弱,而每病变支架长度与任何随访后期事件高风险不相关,表明PCI后第一年内风险已经建立。

结论:在这项对于行PCI并接受新一代DES的女性的汇总分析中,每例患者和每个病变的支架长度是3年主要心血管事件的独立预测因素,但与明确的或可能的支架血栓不相关。
