目的：我们评估了短期暴露于室外空气污染和院外心脏骤停之间的关联在Japanes.Methods：我们研究了558名居民的冈山，日本，谁访问了医院急诊室2006年1月至2010年12月之间的院外心脏骤停使用时间分层病例交叉设计。我们计算了城市代表性的不同空气污染物的平均浓度，并研究了空气污染和心脏骤停之间的关联。结果：暴露于空气污染与心脏骤停的风险升高有关;例如，在过去的48至72小时内，悬浮颗粒物浓度每四分位数范围增加的比值比为1.17（95%置信区间为1.02至1.33）。我们还观察到不同的易感性悬浮颗粒物和臭氧暴露的年龄category.Conclusions：短期暴露于室外空气污染与心脏骤停的风险增加。
Objectives:We evaluated the association between short-term exposure to outdoor air pollution and out-of-hospital cardiac arrest in Japan.Methods:We studied 558 residents of Okayama, Japan, who visited hospital emergency departments between January 2006 and December 2010 for out-of-hospital cardiac arrest using a time-stratified case-crossover design. We calculated city-representative average concentrations of different air pollutants and examined the association between air pollution and cardiac arrest.Results:Exposure to air pollution was associated with an elevated risk of cardiac arrest; for example, odds ratios was 1.17 (95% confidence interval, 1.02 to 1.33) per interquartile-range increase in suspended particulate matter concentrations in the previous 48 to 72 hours. We also observed different susceptibilities to suspended particulate matter and ozone exposures by age category.Conclusions:Short-term exposure to outdoor air pollution was associated with increased risk of cardiac arrest.
