Circulation:秋水仙碱对急性心肌损伤的影响

2021-08-29 MedSci原创 MedSci原创

在这项随机、安慰剂对照试验中,再灌注时和5天口服大剂量秋水仙碱并未降低心脏磁共振成像检查评估的IS。

炎症是再灌注的ST段抬高型心肌梗死患者心肌损伤的关键因素。

近日,血管领域权威杂志Circulation上发表了一篇研究文章,研究人员假设秋水仙碱是一种强效抗炎剂,可以减少ST段抬高型心肌梗死患者急性期梗死面积(IS)和左心室(LV)重构程度。

在这项双盲多中心试验中,研究人员随机分配接受经皮冠状动脉介入治疗的首次ST段抬高心肌梗死住院患者从入院到第5天接受口服秋水仙碱(2mg 负荷剂量,随后每天2次0.5mg)或匹配安慰剂治疗。该研究的主要疗效结局是第5天通过心脏磁共振成像确定的IS。 次要结局为3个月时通过心脏磁共振成像检查评估的相对LV舒张末期容积变化和3个月时的IS情况。

该研究招募了192名患者,其中秋水仙碱组101名,对​​照组91名。5天时,钆增强定义的IS在秋水仙碱组和安慰剂组之间没有差异,LV质量平均为26g(四分位距(IQR)为[16–44])与28.4g(IQR为[14–40])(P=0.87)。在3个月的随访中,秋水仙碱组和安慰剂组的LV重构没有显著差异,LV舒张末期容积变化分别为+2.4%(IQR为–8.3%至11.1%)与–1.1%(IQR为–8.0%至9.9%)(P=0.49)。秋水仙碱组和安慰剂组之间3月时的梗死大小也无显著差异(LV质量分别为17g(IQR[10-28])和18g(IQR[10-27]);P=0.92)。秋水仙碱治疗期间胃肠道不良事件的发生率高于安慰剂(分别为34%和11%;P=0.0002)。

由此可见,在这项随机、安慰剂对照试验中,再灌注时和5天口服大剂量秋水仙碱并未降低心脏磁共振成像检查评估的IS。
