Abstract

Little is known regarding the association between hourly exposure to ambient temperature and temperature change between neighboring days (TCN) with the risk of emergency department (ED) visits for cardiovascular disease (CVD). We conducted a time-stratified case-crossover study among 1.03 million ED visits for CVD between 2016 and 2021 in Zhejiang Province, China. Our analysis reported a reversed J-shaped relationship between hourly ambient temperature and risk of total and cause-specific CVD, with cold having the most significant effects. The risk associated with extreme cold (2.5th percentile of temperature distribution) peaked approximately 40 h after exposure, while the effects of extreme heat (97.5th percentile) were most pronounced during the concurrent hour of exposure (lag 0 h). Additionally, a decline in TCN (negative TCN) was associated with a higher risk of CVD, hypertensive disease, and stroke. In contrast, an increase in TCN (positive TCN) was associated with a lower risk of cause-specific CVD. The risks of negative and positive TCN peaked on the day of exposure and two days after exposure, respectively. These findings suggest that exposure to non-optimal temperature and TCN may increase the risk of ED visits for total and cause-specific CVD shortly after exposure, primarily driven by cold and negative TCN.

暴露于每小时环境温度和相邻天之间的温度变化与因特定原因导致的心血管疾病而到急诊室就诊的风险
人们对每小时暴露于环境温度和相邻天之间的温度变化(TCN)与心血管疾病(CVD)急诊就诊风险之间的关系知之甚少。我们对中国浙江省 2016 年至 2021 年期间因心血管疾病到急诊科就诊的 103 万人次进行了一项时间分层病例交叉研究。我们的分析表明,每小时环境温度与总心血管疾病风险和特异性心血管疾病风险之间存在反向的 "J "形关系,其中寒冷的影响最为显著。极冷(温度分布的 2.5 百分位数)的相关风险在暴露后约 40 小时达到峰值,而极热(97.5 百分位数)的影响在暴露的同时一小时内(滞后 0 小时)最为明显。此外,TCN 的下降(负 TCN)与较高的心血管疾病、高血压疾病和中风风险相关。与此相反,TCN 的增加(正 TCN)与特定病因心血管疾病的较低风险相关。阴性和阳性 TCN 的风险分别在暴露当天和暴露两天后达到峰值。这些研究结果表明,暴露于非最佳温度和TCN可能会在暴露后不久增加因总心血管疾病和特定原因心血管疾病而去急诊室就诊的风险,这主要是由寒冷和负TCN引起的。
