概括

更高的邻里可行性可能会降低缺血性心脏病 (IHD) 风险,而PM2.5暴露会增加它. 可行走的环境可以减轻空气污染对IHD的有害影响.

科学领域:

环境流行病学环境流行病学
心血管疾病的研究研究.
城市规划和公共卫生

背景情况:

以前的研究将邻里可行性与降低缺血性心脏病 (IHD) 风险联系起来.
暴露于细颗粒物 (PM2.5) 与增加IHD风险有关.
可行性和PM2.5对IHD的综合影响需要进一步调查.

研究的目的:

调查社区可行性和PM2.5暴露对缺血性心脏病 (IHD) 风险的联合影响.
探索与IHD相关的可行性和PM2.5之间的潜在相互作用.

主要方法:

在中国宁波市州进行的前性队列研究,共有47516名参与者.
使用可行性数据库和土地使用回归模型 (LUR) 评估个人级别的可行性和PM2.5暴露.
考克斯的比例危险模型和受限制的立方线函数用于分析剂量反应关系和相互作用.

主要成果:

在5.14年的随访中,确定了1735例IHD病例.
增加的PM2.5暴露 (每10μg/m3) 与更高的IHD风险相关 (HR:1.56;95% CI:1.34-1.81).
增加可行性 (每10个单位) 与较低的IHD风险相关 (HR:0.96;95% CI:0.94-0.98),检测到一个显著的相互作用 (Pinteraction = 0.019).

结论:

可行性显示出与IHD风险的逆相关性,而PM2.5暴露显示出正相关性.
更高的可行性可能会减轻PM2.5暴露对IHD风险的不良影响.
促进可步行城市设计和改善空气质量是IHD的关键预防策略.

Ischemic Heart Disease: Overview

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...
