Abstract

Background: The association between aspirin use and the risk of intracerebral hemorrhage (ICH) among individuals without previous stroke events is inconclusive.

Aim: We investigated the association between regular aspirin use and ICH risk in middle-aged and older adults without previous stroke or transient ischemic attack (TIA).

Methods: This prospective population-based study included participants older than 40 years with no history of stroke or TIA from the UK Biobank. The main exposure was regular aspirin use. Cox regression analyses and propensity score matching analyses estimated the hazard ratios (HRs) for aspirin use for incident fatal and non-fatal ICH. We conducted pre-specified subgroup analyses for selecting individuals at high risk of ICH when using aspirin. Multiple sensitivity analyses were performed to test the robustness of our results.

Results: A total of 449,325 participants were included into final analyses (median (IQR) age 58 (50-63) years, 54.6% females), of whom 58,045 reported aspirin use. During a median follow-up of 12.75 (IQR: 12.03-13.47) years, 1557 (0.3%) incident ICH cases were identified, of which 399 (25.6%) were fatal. Aspirin was not associated with increased risk of overall (hazard ratio (HR): 1.11, 95% confidence interval (CI): 0.95-1.27, P = 0.188), fatal (HR: 1.03, 95% CI: 0.78-1.36, P = 0.846) and non-fatal (HR: 1.12, 95% CI: 0.95-1.33, P = 0.186) ICH. Propensity score matching analysis showed similar results. Subgroup analysis indicated that aspirin use in individuals older than 65 years or with concurrent anticoagulant use was correlated with increased risk of ICH.

Conclusion: In this large cohort study of middle-aged and older adults without stroke or TIA events, there was no significant association between aspirin use and ICH risk in the real-world setting. However, it is possible that aspirin use in those aged over 65 years and concurrent anticoagulant treatment may increase the risk of ICH.

英国生物库中无中风或短暂性脑缺血发作史患者服用阿司匹林与脑内出血风险的关系

背景：目的：我们调查了无中风或短暂性脑缺血发作（TIA）史的中老年人定期服用阿司匹林与 ICH 风险之间的关系：这项基于人群的前瞻性研究纳入了英国生物库中 40 岁以上、无中风或 TIA 病史的参与者。主要暴露因素是定期服用阿司匹林。Cox 回归分析和倾向评分匹配分析估算了服用阿司匹林与发生致命性和非致命性 ICH 的危险比 (HRs)。我们进行了预设亚组分析，以筛选出使用阿司匹林时发生 ICH 的高风险人群。我们还进行了多重敏感性分析，以检验结果的稳健性：共有 449,325 名参与者被纳入最终分析（中位数 [IQR] 年龄 58 [50 - 63] 岁，54.6% 为女性），其中 58,045 人报告使用了阿司匹林。在中位数为 12.75（IQR 12.03 - 13.47）年的随访期间，共发现 1,557 例（0.3%）ICH 病例，其中 399 例（25-6%）为致命病例。阿司匹林与总体（HR 1.11，95% CI 0.95 - 1.27，P = 0.188）、致命（HR 1.03，95% CI 0.78 - 1.36，P = 0.846）和非致命（HR 1.12，95% CI 0.95 - 1.33，P = 0.186）ICH 风险增加无关。倾向评分匹配分析显示了相似的结果。亚组分析表明，65 岁以上人群服用阿司匹林或同时服用抗凝剂与 ICH 风险增加相关：结论：在这项针对无中风或 TIA 事件的中老年人的大型队列研究中，阿司匹林的使用与现实世界中的 ICH 风险无明显关联。然而，65 岁以上人群服用阿司匹林并同时接受抗凝治疗可能会增加 ICH 风险。

期刊介绍： The International Journal of Stroke is a welcome addition to the international stroke journal landscape in that it concentrates on the clinical aspects of stroke with basic science contributions in areas of clinical interest. Reviews of current topics are broadly based to encompass not only recent advances of global interest but also those which may be more important in certain regions and the journal regularly features items of news interest from all parts of the world. To facilitate the international nature of the journal, our Associate Editors from Europe, Asia, North America and South America coordinate segments of the journal.
