American Heart Association:极端高温天气会增加1~2倍心血管死亡!

2020-04-02 岱西 中国循环杂志

当新冠病毒疫情在中国暴发时,中国之外似乎尚不觉危险已经临近;当气候变暖时,灾难难道仅仅会落在极地动物身上?

当新冠病毒疫情在中国暴发时,中国之外似乎尚不觉危险已经临近;当气候变暖时,灾难难道仅仅会落在极地动物身上?

近日,发表在Circulation上的一项对科威特地区的研究或能窥见气温升高之危害的一角。

科威特记录到近76年以来地球最高气温:54℃;其平均气温也持续在27.9℃。

这项研究共分析了科威特15609例15岁及以上心血管相关死亡病例与气温之间的关系。

研究显示,就心血管病而言,当日平均气温达到42.8℃极限水平时,死于心血管疾病者将会增加1~2倍。

与死亡率较低水平(日平均气温34.7℃)相比,当24小时平均气温达到42.8℃时:

心血管病死亡风险增加2.09倍;

男性更容易受到极端气温影响,死亡风险升高2.53倍;

15~64岁的劳动年龄人群死亡率升高2.84倍。

在考虑了空气污染、湿度等环境因素后,气温升高对不同年龄和性别的人群仍有差异。

研究者指出,在关注饮食、血压以及烟草等传统心血管病因素对人群的危害时,还需要把眼光放在气候变化上。

他们认为,气候变暖将会让住在原本就很热的地区的居民更为脆弱,或因此而面临更高的死于心血管病的危险中。

虽然这项研究不能确定气温升高和心血管死亡的因果关系,但气候变化带来的危害不能轻视。
