Hurricane Sandy made landfall in New Jersey (NJ) on October 29, 2012. We studied the impact of this extreme weather event on the incidence of, and 30-day mortality from, cardiovascular (CV) events (CVEs), including myocardial infarctions (MI) and strokes, in NJ.
Data were obtained from the MI data acquisition system (MIDAS), a database of all inpatient hospital discharges with CV diagnoses in NJ, including death certificates. Patients were grouped by their county of residence, and each county was categorized as either high- (41.5% of the NJ population) or low-impact area based on data from the Federal Emergency Management Agency and other sources. We utilized Poisson regression comparing the 2 weeks following Sandy landfall with the same weeks from the 5 previous years. In addition, we used CVE data from the 2 weeks previous in each year as to adjust for yearly changes. In the high-impact area, MI incidence increased by 22%, compared to previous years (attributable rate ratio [ARR], 1.22; 95% confidence interval [CI], 1.16, 1.28), with a 31% increase in 30-day mortality (ARR, 1.31; 95% CI, 1.22, 1.41). The incidence of stroke increased by 7% (ARR, 1.07; 95% CI, 1.03, 1.11), with no significant change in 30-day stroke mortality. There were no changes in incidence or 30-day mortality of MI or stroke in the low-impact area.
In the 2 weeks following Hurricane Sandy, there were increases in the incidence of, and 30-day mortality from, MI and in the incidence of stroke.
2012年10月29日，飓风桑迪在新泽西州登陆。我们研究了这一极端天气事件对新泽西州心血管（CV）事件（包括心肌梗死（MI）和中风）的发病率及30天死亡率的影响。
数据来自心肌梗死数据采集系统（MIDAS），该数据库包含新泽西州所有诊断为CV疾病的住院患者出院记录，包括死亡证明。患者按居住县分组，根据联邦紧急事务管理局和其他来源的数据，每个县被分为高影响地区（占新泽西州人口的41.5%）或低影响地区。我们采用泊松回归，将桑迪登陆后的两周与前五年同期的两周进行比较。此外，我们使用每年前两周的CV事件数据来调整年度变化。在高影响地区，与前几年相比，MI发病率增加了22%（归因率比[ARR]，1.22；95%置信区间[CI]，1.16，1.28），30天死亡率增加了31%（ARR，1.31；95%CI，1.22，1.41）。中风发病率增加了7%（ARR，1.07；95%CI，1.03，1.11），30天中风死亡率无显著变化。在低影响地区，MI或中风的发病率及30天死亡率均无变化。
在飓风桑迪过后的两周内，MI的发病率、30天死亡率以及中风的发病率均有所增加。
