盐城地区气候环境因素与急性心肌梗死发病的关系

Relationship between climatic and environmental factors and the incidence of acute myocardial infarction in Yancheng area

目的分析盐城地区急性心肌梗死(AMI)发病与气候因素的关系。方法收集整理2018年3月至2022年1月江苏省盐城地区(4所三级医院:盐城市第一人民医院、盐城市第三人民医院、东台市人民医院、建湖县人民医院;3所二级医院:阜宁县人民医院、射阳县人民医院、响水县人民医院)收治的998例AMI患者的一般资料。气象相关资料出自江苏省盐城市气象局,持续收集研究期间AMI频发日当天、前1天、前2天气象资料。采用logistic多因素回归分析AMI发病与天气的关系。结果研究期间,AMI频发天数为148 d(10.13%),非频发天数为1313 d(89.87%)。冬、春季AMI发病住院患者占比高于夏季和秋季(P<0.05)。AMI频发日前2天平均日变温及平均风速高于AMI非频发日(P<0.05),平均相对湿度低于AMI非频发日(P<0.05)。logistic多因素分析结果显示,AMI频发日前2天平均日变温(OR=3.418,95%CI:1.206~8.759)、平均风速(OR=2.857,95%CI:1.186~7.436)、平均相对湿度(OR=3.159,95%CI:1.054~8.035)均为影响AMI发病的影响因素(P<0.05)。结论AMI发病与平均(日变温、风速、相对湿度)三种气象因素具有一定相关性。

Objective To analyze the relationship between the incidence of acute myocardial infarction(AMI)and climatic factors in Yancheng area.Methods The case data of 998 AMI patients admitted to Jiangsu Province Yancheng area(four tertiary hospitals:Yancheng First People’s Hospital,Yancheng Third People’s Hospital,Dongtai People’s Hospital,Jianhu County People’s Hospital and three secondary hospitals:Funing County People’s Hospital,Sheyang People’s Hospital,Xiangshui County People’s Hospital)from March 2018 to January 2022 were collected.Meteorological data came from Yancheng City,Jiangsu Province.Meteorological data were continuously collected on the day,the previous one day,and the previous two day during the study period when AMI occurred frequently.Logistic multivariate regression analysis was used to analyze the relationship between the incidence of AMI and meteorological factors.Results During the study period,the frequent days of AMI were 148 days(10.13%),and the infrequent days were 1313 days(89.87%).The proportion of inpatients with AMI in winter and spring was higher than those in summer and autumn(P<0.05).The average daily temperature and average wind speed in the two days before the AMI frequent occurrence day were higher than those of the non-frequent AMI occurrence(P<0.05),and the average relative humidity was lower than that of the non-frequent AMI occurrence day(P<0.05).Logistic multivariate analysis results showed that the average daily temperature(OR=3.418,95%CI:1.206-8.759),the average wind speed(OR=2.857,95%CI:1.186-7.436),the average relative humidity(OR=3.159,95%CI:1.054-8.035)were all influence factors affecting the incidence of AMI(P<0.05).Conclusion The incidence of AMI has a certain correlation with meteorological factors of average daily temperature,average wind speed and average relative humidity.
