Weather conditions are thought to increase the risk of stroke occurrence. But their mechanism has not yet been clarified. We investigated possible relationships between ischemic stroke and weather conditions including atmospheric pressure, temperature, relative humidity, and wind speed.
One hundred and twenty-eight patients with ischemic stroke who had been admitted to our hospital between January 1 and December 31, 2010 were enrolled in this study. We investigated the relationship between daily cases and weather conditions the same day or 1, 2, and 3 days before stroke.
A negative correlation was found between maximum wind speed and daily cases 3 days before stroke. As the relationship between daily cases and changes of weather conditions in consecutive days was evaluated, a negative correlation was found between daily cases and change of atmospheric pressure in the last 24 hours.
The maximum wind speed 3 days before stroke and change of atmospheric pressure in the last 24 hours were found to increase the cases of ischemic stroke. We recommend that individuals at risk of ischemic stroke should pay more attention to preventive measures, especially on days with low maximum wind speed, on subsequent 3 days, and on days with low atmospheric pressure in the last 24 hours.
天气状况被认为会增加中风发生的风险。但其机制尚未阐明。我们研究了缺血性中风与包括大气压、温度、相对湿度和风速在内的天气状况之间的可能关系。
本研究纳入了2010年1月1日至12月31日期间在我院住院的128例缺血性中风患者。我们调查了每日发病病例与中风当天或中风前1、2和3天的天气状况之间的关系。
发现中风前3天的最大风速与每日发病病例呈负相关。在评估每日发病病例与连续几天天气状况变化之间的关系时,发现每日发病病例与过去24小时内的气压变化呈负相关。
中风前3天的最大风速和过去24小时内的气压变化会增加缺血性中风的发病例数。我们建议,缺血性中风高危个体应更加注意预防措施,尤其是在随后3天最大风速较低的日子以及过去24小时内气压较低的日子。
