JAHA:白细胞介素6与射血分数正常心衰的关系

2021-05-17 MedSci原创 MedSci原创

IL-6水平与社区居民中新发HFpEF相关,独立于潜在的混杂因素。该研究的结果值得进一步研究,以调查IL-6是否可能是预防HFpEF的新型治疗靶标。

射血分数正常心衰(HFpEF)的病因尚未明确,并且缺乏具体的疗法。既往的研究表明炎症在HFpEF的发生中起作用。

近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,该研究旨在调查社区居民个人血浆白细胞介素6(IL-6)水平升高是否与新发心衰(HF),尤其是HFpEF,风险增加相关。

该病例队列研究是基于肾脏和血管终末期疾病预防(PREVEND)研究。研究人员纳入了961名参与者,包括200名发展为HF的参与者和761名随机对照者。分别以左心室射血分数≤40%或>40%来定义射血分数降低的HF或HFpEF。

IL-6与HF

在Cox比例风险回归分析中,对关键危险因素调整后,IL-6水平与HF的发生在统计学上显著相关(风险比[HR]为1.28;95%CI为1.02-1.61;P=0.03)。具体而言,IL-6水平与HFpEF的发生显著相关(HR为1.59;95%CI为1.16-2.19;P=0.004),而与射血分数降低的HF无关(HR为1.05;95%CI为0.75-1.47;P=0.77)。在敏感性分析中,将HFpEF定义为左心室射血分数≥50%,IL-6水平也与调整关键危险因素后的HFpEF发生显著相关(HR为1.47;95%CI为1.04-2.06;P=0.03)。

由此可见,IL-6水平与社区居民中新发HFpEF相关,独立于潜在的混杂因素。该研究的结果值得进一步研究,以调查IL-6是否可能是预防HFpEF的新型治疗靶标
