热带气旋 (TCs) 增加了心血管疾病 (CVD) 的住院治疗,风险在暴露后两个月达到顶峰. 缺血性心脏病和中风的负担更高,特别是在贫困人口中.
科学领域:
- 环境健康 环境健康
- 心血管医学 心血管医学
- 气候变化影响 气候变化影响
背景情况:
- 热带气旋 (TCs) 是显著的极端气候,其间接健康风险不明.
- 心血管疾病 (CVD) 是一个主要的健康问题,是导致死亡的重要因素.
- 了解TC的长期健康负担对于公共卫生准备至关重要.
研究的目的:
- 量化TC暴露后心血管疾病住院的长期风险和负担.
- 为了调查特定原因的CVD风险和TC后的时间模式.
- 检查TC归因于CVD负担的社会经济差异.
主要方法:
- 两个阶段的时间序列分析应用于65.4万例心血管疾病住院病例.
- 从2000年至2019年收集了6个国家/地区 (加拿大,新西兰,韩国,台湾,泰国,越南) 的数据.
- 分析的重点是医院住院风险和TC暴露后的时间趋势.
主要成果:
- 心血管疾病住院的风险在TC暴露后持续增加,在2个月左右达到峰值,并在6个月后消散.
- 每一个额外的TC日与6个月内心血管疾病住院病例增加13%有关.
- 缺血性心脏病和中风显示特别高的TC归因负担,特别是在男性,年轻人 (20-59岁) 和社会经济贫困群体.
结论:
- TCs对心血管疾病住院造成显著的间接风险,在心血管疾病类型和人口群体之间产生不同的影响.
- 社会经济贫困与TC归因的CVD住院病例的增加趋势有关.
- 公共卫生战略应解决与极端气候有关的心血管负担,重点关注弱势群体.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases.
