Abstract

Background: Both genetic and lifestyle factors contribute to myocardial infarction (MI) and stroke, including ischaemic stroke (IS) and intracerebral haemorrhage (ICH). We explored how and the extent to which a healthy lifestyle, by considering a comprehensive list, could counteract the genetic risk of those diseases, respectively.

Methods: 315 044 participants free of stroke and MI at baseline were identified from the UK Biobank. Genetic risk scores (GRS) for those diseases were constructed separately and categorised as low, intermediate and high by tertile. Lifestyle risk scores (LRS) were constructed separately using smoking, alcohol intake, physical activity, dietary patterns and sleep patterns. Similarly, participants were categorised into low, intermediate and high LRS. The data were analysed using Cox proportional hazard models.

Results: Over a median follow-up of 12.8 years, 4642, 1046 and 9485 participants developed IS, ICH and MI, respectively. Compared with participants with low levels of GRS and LRS, the HRs of those with high levels of GRS and LRS were 3.45 (95% CI 2.71 to 4.41), 2.32 (95% CI 1.40 to 3.85) and 4.89 (95% CI 4.16 to 5.75) for IS, ICH and MI, respectively. Moreover, among participants with high GRS, the standardised 14-year rates of IS events were 4.40% (95% CI 3.45% to 5.36%) among those with high LRS. In contrast, it is only 1.78% (95% CI 1.63% to 1.94%) among those with low LRS. Similarly for MI, the high LRS group had standardised rates of 8.60% (95% CI 7.38% to 9.81%), compared with 3.34% (95% CI 3.12% to 3.56%) in low LRS. Among the high genetic risk group of ICH, the rate is reduced by about half compared low LRS to high LRS, although the rate was low for both (0.36% (95% CI 0.31% to 0.42%) and 0.71% (95% CI 0.36% to 1.05%), respectively).

Conclusion: Healthy lifestyles were substantially associated with a reduction in the risk of IS, ICH and MI and attenuated the genetic risk of IS, ICH and MI by at least half, respectively.

健康的生活方式可降低缺血性中风、脑出血和心肌梗死的单核苷酸多态性遗传风险。

背景：遗传因素和生活方式因素都会导致心肌梗死（MI）和中风，包括缺血性中风（IS）和脑内出血（ICH）。我们探讨了健康的生活方式如何以及在多大程度上通过考虑综合清单来分别抵消这些疾病的遗传风险。方法：从英国生物库中确定了 315 044 名基线时没有中风和心肌梗死的参与者。分别构建了这些疾病的遗传风险评分（GRS），并按三等分将其分为低、中、高三类。生活方式风险评分（LRS）是通过吸烟、酒精摄入、体育锻炼、饮食模式和睡眠模式分别得出的。同样，参与者也被分为低、中和高 LRS。数据采用 Cox 比例危险模型进行分析：在12.8年的中位随访期间，分别有4642、1046和9485名参与者发生了IS、ICH和MI。与GRS和LRS水平低的参与者相比，GRS和LRS水平高的参与者发生IS、ICH和MI的HR分别为3.45（95% CI 2.71至4.41）、2.32（95% CI 1.40至3.85）和4.89（95% CI 4.16至5.75）。此外，在 GRS 偏高的参与者中，LRS 偏高者的 14 年 IS 事件标准化发生率为 4.40%（95% CI 3.45% 至 5.36%）。相比之下，低 LRS 参与者的 IS 事件标准化 14 年发生率仅为 1.78%（95% CI 1.63% 至 1.94%）。同样，在心肌梗死方面，高 LRS 组的标准化发病率为 8.60%（95% CI 7.38% 至 9.81%），而低 LRS 组为 3.34%（95% CI 3.12% 至 3.56%）。在 ICH 高遗传风险组中，低 LRS 比高 LRS 的发病率降低了约一半，尽管两者的发病率都很低（分别为 0.36% (95% CI 0.31% to 0.42%) 和 0.71% (95% CI 0.36% to 1.05%)）：结论：健康的生活方式与IS、ICH和MI风险的降低密切相关，并可将IS、ICH和MI的遗传风险分别降低至少一半。
