基因与环境的相互作用显著增加了心肌梗塞 (MI) 风险. 高遗传倾向与空气污染暴露相结合,构成最大的肌肉感染风险,强调了这两个因素在疾病预防中的重要性.
科学领域:
- 环境健康 环境健康
- 心血管流行病学心血管流行病学
- 遗传学 遗传学 是一个
背景情况:
- 基因与环境的相互作用对于理解疾病病因至关重要.
- 关于遗传易感性和空气污染对心肌梗塞 (MI) 风险的综合影响的知识有限.
- 空气污染物对社区人口中心脏病发病率的长期影响需要进一步调查.
研究的目的:
- 调查遗传倾向和空气污染暴露对MI发病率的相互作用.
- 量化与遗传因素和空气污染物相关的MI综合风险.
主要方法:
- 利用了来自456,354名参与者的英国生物库数据 (2006-2021年).
- 评估了对特定空气污染物的慢性暴露 (
- 采用考克斯的比例危险模型和计算的多基因风险评分 (PRS) 来分析基因环境相互作用,在增量和乘数尺度上进行分析.
主要成果:
- 在12.08年的中位数随访期间观察到9,114起 MI 事件.
- 长期暴露于所有测量的空气污染物与心脏病发作风险增加有关.
- 高PRS和高空气污染暴露的参与者表现出最高的MI风险 (高达324%的增加),检测到显著的乘法和添加相互作用.
结论:
- 环境空气污染物暴露与与心脏病发作风险相关的遗传易感性之间存在显著的相互作用.
- 空气污染和遗传倾向对心脏病发病率的综合影响大于它们个别影响的总和.
