美国心脏病学会(ACC)2012年年会上公布的CPORT-E研究是一项非劣势临床研究,也是第一个在没有心脏外科的医院行非急诊PCI的随机对照临床试验。针对短期(6周)死亡率和长期(9个月)主要不良心血管事件发生率的研究结果表明,所在医院有心血管外科与没有心血管外科相比,两组之间非急诊PCI的主要心血管不良事件没有显着差异。近期,研究人员对CPORT-E研究进行了再次分析发现,在非急诊PCI术后的6周和9个月时,女性比男性更可能发生心绞痛。

既往研究表明,与男性相比,接受PCI的女性冠心病患者合并症更多、治疗积极性更差、长期发病率更高、术后功能状态更差、心绞痛更频繁。为深入了解性别差异对临床结果和健康状况的影响,研究人员通过分析CPORT-E试验中收集的数据,比较了接受非急诊PCI治疗的6851例女性和12,016例男性患者在基线、6周和9个月时的西雅图心绞痛问卷(Seattle Angina Questionnaire)评分情况。

研究结果显示,与男性相比,女性在PCI术后9个月时服用他汀类药物的频率较低(83.1% vs. 86.5%)、出院时接受的双联抗血小板治疗也较少(93% vs. 94.5%),尽管这种差异随着时间的推移而缩小。在9个月内,与男性相比,女性服用阿司匹林的频率较低(92.4% vs. 94.4%),而服用P2Y12抑制剂的频率更高(88% vs. 86.9%);使用β受体阻滞剂的情况男女患者相似。

男性和女性的6周全因死亡率(1.12% vs. 0.84%,P=0.053;aOR 1.15,95%CI 0.79-1.66,P=0.47)和MACE(12.4% vs. 11.9%,P=0.15;aOR 1,95%CI 0.91-1.12,P=0.87)发生率没有差异。然而,女性出血(8.5% vs. 3.7%;aOR 1.8,95%CI 1.4-2.5;P<0.001)、血管修复术(1.6% vs. 1.1%;aOR 1.8,95%CI 1.6-2.1;P<0.001)和重复诊断性导管插入术(16.4% vs. 12.4%;aOR 1.41,95%CI 1.3-1.5;P<0.001)的频率更高。

在基线、6周和9个月时,除治疗满意度外(6周时P=0.081;9个月时 P=0.27),女性的西雅图心绞痛问卷评估的健康状况在所有方面相比男性较差(均P<0.001)。在调整临床特征、程序特征和基线西雅图心绞痛问卷评分后,女性在6周(β=2.67,95%CI 3.08-2.27;P<0.001)和9个月(β=2.36,95%CI 2.74-1.97;P<0.001)时的健康状况相比男性依然较差。此外,女性在6周(OR 0.66;95%CI 0.61-0.71;P <0.001)和9个月(OR 0.68;95%CI 0.62-0.74;P <0.001)时的无心绞痛几率相比男性也较低。
