Stroke:卒中后长期服用普拉格雷或氯吡格雷治疗的血压和变异性水平

2021-02-11 MedSci原创 MedSci原创

较高的平均SBP水平和随访变异性与普拉格雷或氯吡格雷长期治疗期间卒中复发的风险显着相关。无论使用哪种抗血小板药物,控制高血压都尤为重要。

高血压会增加抗血栓药物治疗期间的出血风险。然而,采用噻吩并吡啶(尤其是普拉格雷)进行长期预防继发性卒中期间血压水平与复发性卒中风险之间的关系尚未得到很好的研究。

这项随机、双盲、多中心PRASTRO-I试验(日本缺血性卒中I患者的普拉格雷和氯吡格雷疗效比较试验)。非心脏栓塞性卒中患者被随机分配(1:1)接受普拉格雷3.75 mg /天或氯吡格雷75 mg/天,持续治疗96至104周。根据观察期间收缩压(SBP)的平均水平和随访变异性(包括连续变异性)来确定缺血性或出血性卒中、合并缺血性事件和合并出血事件的风险。这些风险也在平均收缩压水平和收缩压连续变化的四分位数之间进行了比较。

该研究共有3747例患者(年龄为62.1±8.5岁,797名女性),在观察期内,平均SBP水平为132.5 mmHg。所有卒中(146次;风险比为1.318 [95%CI为1.094-1.583]/10mmHg)、缺血性卒中(133例,1.219[1.010-1.466])、出血性卒中(13例,3.247[1.660-6.296])、缺血性事件(142例,1.219[1.020-1.466])、出血事件(47例,1.629[1.172-2.261])风险与整体平均SBP增加相关。同样,这些事件风险增加与SBP连续变化增加相关(每增加10mmHg,相应风险比分别为3.078 [95%CI为2.220-4.225];3.051 (2.179-4.262);3.276 (1.172-9.092);2.865(2.042-4.011);2.764(1.524-5.016))。在SBP四分位数或SBP连续变化内,氯吡格雷组和普拉格雷组的事件发生率没有差异。

由此可见,较高的平均SBP水平和随访变异性与普拉格雷或氯吡格雷长期治疗期间卒中复发的风险显着相关。无论使用哪种抗血小板药物,控制高血压都尤为重要
