This study aimed to examine the effects of flooding due to Typhoon Hagibis on the incidence of cardiovascular/cerebrovascular events in Nagano City.
The SAVE trial retrospectively enrolled 2426 patients hospitalized for cardiovascular/cerebrovascular disease in 5 hospitals in Nagano City from October 1 to December 31 in 2017 and 2018 (pre-disaster period) and in 2019 (post-disaster period). From these, 280 patients who were hospitalized in a district flooded in 2019 were recruited for the same period (October 12 to December 31) over the 3 years. The baseline characteristics of and the incidence of cardiovascular/cerebrovascular disease in cases from the flooded district in 2019 were compared with those of cases in the flooded district in 2017 and 2018.
The total number of patients with acute myocardial infarction did not differ significantly between the post- and pre-disaster periods. The incidence of unstable angina pectoris was significantly higher in 2019 (n = 4, 5.1%) than in 2017 and 2018 (n = 0, 0.0%) ( = 0.001).
This study did not prove the impact of flood due to a typhoon on the incidence of cardiovascular/cerebrovascular events.
本研究旨在调查台风海贝斯引发的洪水对长野市心血管/脑血管事件发生率的影响。
SAVE试验回顾性纳入了2017年和2018年（灾前时期）以及2019年（灾后时期）10月1日至12月31日期间在长野市5家医院因心血管/脑血管疾病住院的2426例患者。其中，选取了2019年被洪水淹没地区同期（10月12日至12月31日）3年期间住院的280例患者。比较了2019年洪水受灾地区病例与2017年和2018年洪水受灾地区病例的心血管/脑血管疾病基线特征和发病率。
急性心肌梗死患者总数在灾后和灾前时期之间无显著差异。2019年不稳定型心绞痛的发病率（n = 4，5.1%）显著高于2017年和2018年（n = 0，0.0%）（P = 0.001）。
本研究未证实台风引发的洪水对心血管/脑血管事件发生率的影响。
