Several studies have suggested a relationship between weather parameters and the occurrence of sudden cardiac death.
The aim of this work was to study the impact of changes in temperature and humidity level on the occurrence of sudden cardiac death in the north of Tunisia.
it's an autopsic study that included all victims of sudden cardiac death occurring in northern Tunisia between October 2010 and September 2012. The minimum, maximum and average of daily temperatures and humidity during the study period were recorded and compared with the monthly variation in the occurrence of sudden death.
The study population included 392 men and 108 women with a mean age of 52.2 + / - 15.8 years.The highest rate of sudden death (37%) was observed at ambient temperatures below 15 degrees and only 4.2% of deaths occurred at temperatures above 30 degrees ambient temperatures (p <0.001). Among the population aged over 60 years, the highest mortality rate (47.3%) were recorded at temperatures below 15 degrees, while 35.5% of young patients under 40 years died during periods with temperatures between 20 and 30 degrees and 56.8% of deaths occurred in the humidity levels between 60 and 78% .
In the north of Tunisia where the climate is temperate, a temperature drop below 15 degrees was significantly associated with a sudden cardiac death. This excess winter cardiac mortality was more pronounced in the elderly.
多项研究表明天气参数与心源性猝死的发生之间存在关联。
本研究旨在探讨突尼斯北部温度和湿度变化对心源性猝死发生情况的影响。
这是一项尸检研究，纳入了2010年10月至2012年9月期间突尼斯北部所有心源性猝死的受害者。记录研究期间每日温度和湿度的最低值、最高值及平均值，并与猝死发生情况的月度变化进行比较。
研究人群包括392名男性和108名女性，平均年龄为52.2±15.8岁。在环境温度低于15度时观察到最高的猝死率（37%），而在环境温度高于30度时仅有4.2%的死亡发生（p<0.001）。在60岁以上人群中，温度低于15度时记录到最高死亡率（47.3%），而40岁以下的年轻患者中有35.5%在温度介于20至30度期间死亡，56.8%的死亡发生在湿度水平介于60%至78%之间时。
在气候温和的突尼斯北部，温度降至15度以下与心源性猝死显著相关。这种冬季心脏死亡率的增加在老年人中更为明显。
