摘要
目的了解气象因素对急性心肌梗死发病的影响。方法收集太原市区内四所医院心内科1999年—2003年收治的太原地区1 668例急性心肌梗死患者资料。采集患者的发病时间、年龄、性别以及有无高血压病和糖尿病病史。整理来自山西气象中心提供的太原地区1999年—2003年每日的平均气压、气温、相对湿度、降水量和平均风速等气象资料,运用广义可加模型(GAM)分析各气象因素对急性心肌梗死发病的影响。结果当日的气压对急性心肌梗死发病的影响有统计学意义(P=0.023),并且气压的滞后性影响也有统计学意义(P=0.027);当日气温对急性心肌梗死发病的影响有统计学意义(P=0.003),气温的滞后性影响也有统计学意义(P=0.035);当日的平均相对湿度对急性心肌梗死发病的影响有统计学意义(P=0.035);当日的平均风速对急性心肌梗死发病的影响有统计学意义(P=0.006);平均相对湿度和平均风速无滞后性影响,降水量未进入模型。结论气压、气温、相对湿度和平均风速对急性心肌梗死的发病有影响,但非线性相关,并且气压和气温有滞后性影响。
Objective To investigate the effect of climate factors on acute myocardial infarction(AMI) in Taiyuan region.Methods A total of 1 668 consecutive patients(pts) with AMI admitted to 4 coronary care units from Jan 1999 to Dec 2003 were collected for retrospective studies.Generalized additive model(GAM) was used to reveal the relation between AMI and atmospheric pressure,temperature,relative humidity,rainfall,and wind speed.Results Atmospheric pressure:When atmospheric pressure at 9250 hPa to 9350 hPa,there were no relation between the atmospheric pressure and the onset of AMI.But the atmospheric pressure increased above this range,the onset of AMI were relative to atmospheric pressure(P=0.023).Temperature:When the temperature in 15 ℃to 20 ℃,there was no relation between the temperature and onset of AMI,and when temperature less than 15℃,there was a negative relation.If temperature more than 20 ℃,there was a tendency with a high incidence of AMI(P=0.003).The relative humidity(P=0.035)and wind speed(P=0.006) were related to the onset of AMI in the first day of onset of disease significantly.The weather factors with lagging effect in 5 day were atmospheric pressure(P=0.027) and temperature(P=0.035).Conclusion The results suggested that the onset of AMI was significantly influenced by climate factors,which were the atmospheric pressure,temperature,relative humidity and wind speed in the first day of the AMI.
