Stroke:为期42年的双胞胎随访研究证实,吸烟在致死性蛛网膜下腔出血中起因果作用

近日发表在Stroke上的一项对芬兰双胞胎队列长达42年的随访分析中发现,吸烟可能增加致命性蛛网膜下腔出血的风险,并可能影响这一事件的家族表现,该研究为吸烟和脑出血之间的联系提供了进一步的证据。

近日发表在Stroke上的一项对芬兰双胞胎队列长达42年的随访分析中发现,吸烟可能增加致命性蛛网膜下腔出血的风险,并可能影响这一事件的家族表现,该研究为吸烟和脑出血之间的联系提供了进一步的证据。

研究人员分析了1976年至2018年芬兰双胞胎队列中16,282对同性双胞胎的数据。调查在基线进行,以收集有关高血压、吸烟、BMI、休闲体育活动、饮酒和教育的信息。并使用经过验证的问卷确定患者是单合子(monozygotic)、双合子(dizygotic)还是未知合子(unknown zygosity)。研究人员将受试者分为吸烟者(偶尔和现在)或不吸烟者(从不吸烟者和曾经吸烟者),并进行了长达42年的吸烟与致死性蛛网膜下腔出血之间的随访研究,通过全国范围的死因登记系统获得了后续的死亡率数据。

随访869,469人-年期间,共发生120例致死性蛛网膜下腔出血事件,其中4例为双胎;116例为双胞胎中一个,其中25例是单合子,72例是双合子,19例是未知合子。在整个队列中,与从不吸烟或曾经吸烟的人相比,偶尔或现在吸烟的受试者死于蛛网膜下腔出血的风险增加(HR=3.33;95%CI 2.24-4.95)。

研究人员还对双胞胎中一个死于蛛网膜下腔出血的人群进行了配对分析,发现吸烟的双胞胎比不吸烟的双胞胎患致命性蛛网膜下腔出血的风险更高(HR=6.33;95%CI 1.87-21.4)。

研究结果表明吸烟可能是引起蛛网膜下腔出血的家族性表现,并与强有力的因果关系证据相一致。这一发现与先前报道的吸烟与这种危及生命的卒中类型之间的密切关系是一致的。

美国心脏协会(AHA)科学和医学副主任、AHA烟草监管科学中心联合主任Rose Marie Robertson博士说:“这项针对双胞胎的长期研究有助于确认蛛网膜下腔出血与吸烟之间的联系。不要吸烟,如果你已经开始吸烟,请马上戒烟,这是初级预防的一个重要组成部分。”
