Eur Heart J:阿司匹林对糖尿病患者痴呆和认知功能的影响

2022-04-11 MedSci原创 MedSci原创

阿司匹林对痴呆症的风险没有很大的比例效应。每日服用低剂量阿司匹林长达平均7.4年,对广义或狭义痴呆结局的风险均无统计学意义。

在初级心血管疾病预防中,最近的随机试验荟萃分析显示,每日低剂量阿司匹林可使主要血管事件的风险按比例降低11%(包括缺血性卒中的风险降低19%),但严重出血的风险按比例增加43%脑血管事件与认知障碍相关,因此,阿司匹林可能通过避免缺血性卒中、短暂性缺血发作(TIA)和微梗死预防认知障碍,但可能通过增加颅内出血和脑微出血的风险而导致认知障碍。阿司匹林广泛用于心血管疾病的预防,但也与出血风险增加有关。阿司匹林对痴呆和认知障碍的净效果尚未明确。

近日,心血管领域权威杂志Eur Heart J上发表了一篇研究文章,在ASCEND试验中,15480名来自英国的糖尿病患者,无心血管疾病史。受试者被随机分为接受每天100mg的阿司匹林和匹配的安慰剂治疗,平均治疗持续时间为7.4年。

15427名基线前无痴呆记录的ASCEND参与者被纳入这项认知研究,他们的主要预后为“广泛性痴呆”,包括痴呆、认知障碍或意识混乱。这是在2019年3月31日前通过参与者、护理人员或全科医生报告或住院诊断(比预定治疗期多出2年)来确定。

在阿司匹林组和安慰剂组中,发生广泛痴呆结局的参与者比例相似,分别为548名(7.1%)参与者 vs. 598名(7.8%)参与者,比率为0.91[95%置信区间(CI)为0.81-1.02]。

由此可见,阿司匹林对痴呆症的风险没有很大的比例效应。每日服用低剂量阿司匹林长达平均7.4年,对广义或狭义痴呆结局的风险均无统计学意义。
