JAHA:高 Lp-PLA2酶活性与心血管事件相关

2016-06-28 phylis 译 MedSci原创

背景:在ATABILITY试验中,研究者评估了稳定性冠心病应用选择性Lp-PLA2抑制剂(Darapladib)治疗前和治疗期间,血浆脂蛋白相关磷脂酶A2(Lp-PLA2)的活性与预后以及Darapladib对预后的影响的相关性。方法和结果:确定基线(n = 14500),1个月(n = 13709),连续3、6、18个月(N = 100)以及治疗结束时血浆Lp-PLA2活性。校正后Cox回归模型

背景:在ATABILITY试验中,研究者评估了稳定性冠心病应用选择性Lp-PLA2抑制剂(Darapladib)治疗前和治疗期间,血浆脂蛋白相关磷脂酶A2(Lp-PLA2)的活性与预后以及Darapladib对预后的影响的相关性。

方法和结果:确定基线(n = 14500),1个月(n = 13709),连续3、6、18个月(N = 100)以及治疗结束时血浆Lp-PLA2活性。校正后Cox回归模型评估Lp-PLA2活性水平和预后之间的关联。在基线时,平均Lp-PLA2水平每公升172.4μmol /min(间距范围:每公升143.1-204.2μmol /min)。比较最高和最低四分位数的Lp-PLA2活性,校正基线特征,标准的实验变量及其他的预后标志物后,主要复合终点(心血管死亡、心肌梗死、或卒中)的危险比为1.50(95% CI 1.23-1.82),心脏衰竭住院的HR为1.95(95% CI 1.29-2.93),心血管死亡的HR为1.42(1.07-1.89),心肌梗死的HR 为1.37(1.03-1.81)。Darapladib治疗导致Lp-PLA2活性的中位数呈65%持续减少。治疗中Lp-PLA2酶活性或者 Lp-PLA2酶活性的变化与预后没有显著的关联,基线和治疗时酶活性或酶活性水平的变化与Darapladib对预后的影响没有显著地变化。

结论:虽然高Lp-PLA2酶活性与心血管事件风险增加相关,药物降低Lp-PLA2活性≈65%不能显著稳定降低稳定性冠心病患者的心血管事件的发生,无论基线水平Lp-PLA2活性或Lp-PLA2活性变化幅度。
