This study was the first to explore the relationship between Asian dust storm events (ADS) and acute myocardial infarction (AMI) hospital admissions by applying time series models.
Nationwide population-based hospitalization claims data in Taiwan were used. There were 143,063 AMI admissions during 2000-2009.
An autoregressive with exogenous variables (ARX) time series model was used to investigate the dynamic connection between AMI hospital admissions and ADS events.
AMI hospitalizations significantly spiked on post-ADS day three. Among the total population, 3.2 more cases of AMI admissions occurred on post-ADS day three. When the data were stratified by age and gender, the same delayed effect was present in the male population, especially those aged 45-64 and over 74.
Our study shows that although an ADS event does not cause an immediate incidence of AMI, storms may increase AMI incidence through a delayed effect. Hence, AMI prevention is not only important during a dust storm, but particularly so in subsequent days. During the days after an ADS, exposure to dust should be minimized by staying indoors as much as possible and by wearing a mask when exposure to dust is unavoidable. This is especially true for working and older adults. Nurses at local public health centers can increase awareness and promote public safety by providing health information to local communities regarding the link between dust storms and AMI.
本研究首次通过时间序列模型探讨亚洲沙尘暴事件（ADS）与急性心肌梗死（AMI）住院人数之间的关系。
本研究使用了台湾基于全国人口的住院记录数据。2000 年至 2009 年共有 143063 例 AMI 住院病例。
采用自回归外生变量（ARX）时间序列模型，探讨 AMI 住院人数与 ADS 事件之间的动态联系。
AMI 住院人数在 ADS 发生后第三天显著上升。在总人口中，ADS 发生后第三天增加了 3.2 例 AMI 住院病例。在按年龄和性别分层的数据中，男性人群存在相同的滞后效应，尤其是 45-64 岁和 74 岁以上的男性人群。
本研究表明，尽管 ADS 事件不会立即导致 AMI 发病，但风暴可能通过滞后效应增加 AMI 发病风险。因此，AMI 预防不仅在沙尘暴期间很重要，而且在随后的几天也很重要。在 ADS 发生后的几天内，应尽量减少暴露于灰尘中，尽可能待在室内，并在无法避免暴露于灰尘时佩戴口罩。对于工作人群和老年人来说尤其如此。当地公共卫生中心的护士可以通过向当地社区提供有关沙尘暴与 AMI 之间联系的健康信息，提高认识并促进公众安全。
