目的：确定 2004 年 10 月的新泻中越地震是否增加了急性心肌梗塞 (AMI) 的长期死亡率。设计：通过分析 1999 年 10 月 1 日至 2007 年 9 月 30 日的死亡证明数据，对地震前后以及灾区和控制区之间的死亡率进行比较研究。背景：新泻县灾区和控制区（10 月 1 日 n=2 448 025） 2004）日本。人口：地震前五年（12 333 429 人年）和地震后三年（7 279 076 人年）观察到的新泻县总人口。主要结果指标：AMI 死亡率（ICD-10、I21 和 I22）。结果：灾区地震前 5 年和地震后 3 年 AMI 的总体死亡率为每 10 万人年分别为 47.3 和 53.9。与死亡率分别为每10万人年42.5和42.6的对照区相比，变化（+6.6或+14.0%）显着不同（p=0.0008），但没有显着差异（p=0.9028）。在男性中，灾区地震前后 AMI 死亡率的变化为每 10 万人年+7.1（+13.4%，p=0.0172），而对照地区则为+2.0（+4.2%，p=0.2362）。在女性中，灾区的 AMI 死亡率变化为每 10 万人年 +6.2（+14.9%，p=0.0184），而对照地区则为 21.6（24.2%，p=0.2735）。 结论：新泻中越地震显着增加了男性和女性 AMI 的长期死亡率。公共卫生领域的临床医生和政策制定者必须认识到在地震灾区长期预防 AMI 的必要性。
Objective: To determine if the Niigata-Chuetsu earthquake of October 2004 increased long-term mortality from acute myocardial infarction (AMI).Design: A comparative study of mortality rates before and after the earthquake, as well as between the disaster and control areas, by analysing death certificate data from 1 October 1999 to 30 September 2007.Setting: The disaster area and a control area in Niigata Prefecture (n=2 448 025 in 1 October 2004) in Japan.Population: The total population of Niigata Prefecture observed for five years (12 333 429 person-years) before and three years (7 279 076 person-years) after the earthquake.Main outcome measures: Mortality from AMI (ICD-10, I21 and I22).Results: Overall mortality rates from AMI five years before and three years after the earthquake in the disaster area were 47.3 and 53.9 per 100 000 person-years, respectively. Change (+6.6 or +14.0%) was significantly different (p=0.0008), compared to the control area, where mortality rates were 42.5 and 42.6 per 100 000 person-years, respectively, and was not significantly different (p=0.9028). In men, a change in AMI mortality before and after the earthquake in the disaster area was +7.1 per 100 000 person-years (+13.4%, p=0.0172), and +2.0 (+4.2%, p=0.2362) in the control area. In women, a change in AMI mortality in the disaster area was +6.2 per 100 000 person-years (+14.9%, p=0.0184) and 21.6 (24.2%, p=0.2735) in the control area.Conclusions: The Niigata-Chuetsu earthquake significantly increased long-term mortality from AMI in both men and women. Clinicians and policymakers in public health must recognise the need for long-term prevention of AMI in earthquake disaster areas.
