JACC:强化收缩压治疗的获益和风险并存!

欲戴王冠,必承其重!强化收缩压治疗,欲得其益,必承其风险!

对高CVD风险的患者进行强化收缩压(SBP)治疗可预防血管疾病(CVD)事件,虽然获益可能因人而异。

该研究旨在预测强化和标准SBP治疗带来的益处(降低CVD和全因死亡率风险)以及不良事件(AE)风险。

这是对SPRINT试验(收缩压干预试验)进行的二次分析。受益结果包括:1)急性心肌梗死或其他急性冠状动脉综合征、卒中、心力衰竭或CVD死亡的CVD复合结果;2)全因死亡率。与治疗相关的不良事件包括低血压、晕厥、心动过缓、电解质异常、伤害性跌倒和急性肾损伤。采用改良的弹性净Co??x回归根据强化治疗与标准治疗的护理点上可用的36个基线变量来预测每种结果的绝对风险和绝对风险差异。

预测的两组CVD复合结局风险

在SPRINT试验8828位受试者(平均67.9岁,35% 女性)中,中位随访了3.26年后,共发生了600例CVD复合事件,363例全因死亡和481例治疗相关不良事件。研究人员分别预测了个体受试者的CVD复合风险(C指数 0.71)、全因死亡风险(0.75)和治疗相关不良事件风险(0.69)。

获益和不良事件风险相关性

高基础CVD风险与干预治疗获益更多相关(如 CVD风险降低绝对值更高)。预测的CVD获益和预测的治疗相关不良事件风险增加相关(Spearman相关系数 -0.72),95%的处于预期获益最高三分位数的受试者的与治疗相关的AE风险的预测值表现为较高或中等程度的增加。很少的患者为预测高获益且低不良事件风险(1.8%)或低获益而高不良事件风险(1.5%)。在全因死亡率方面上也观察到了类似的结果。

总之,对于SPRINT试验受试者,基线预测的CVD风险越高,从强化收缩压治疗中的获益越大。但是,预测获益越大的个体,预测的面临的不良事件风险也越高。研究人员认为,基于预测的高获益,应优先考虑予以患者进行强化SBP治疗。
