气象因素对急性心肌梗塞发病的影响及因时护理措施

The Effect of Climatic Factors on the Onset of Acute Myocardial Infarction

对于处于东北寒冷地区的沈阳市急性心肌梗塞发病与气温、气压、相对湿度3大气象因素进行单相关分析。结果表明：急性心肌梗塞的发病以高温、高湿、低气压的夏季最多。急性心肌梗塞发病与气温呈曲线相关（r＝0．7463P＜0．01）；与气压呈负相关（r＝-0．7300P＜0．05）；与相对湿度呈正相关（r＝0.6466P＜0.01）。提示沈阳市急性心肌梗塞的发病在夏季平均气温20℃以上，平均气压1010以下，相对湿度70％以上的条件下发病明显增高。因此心肌梗塞患者要减少在高温、寒冷环境下活动时间，要做到“夏病春治，冬病秋治”，未病先防，顺应四时气候变化，不同季节采取不同的护理措施，避免因气象因子的影响而导致急性心肌梗塞的发生。

The results of the single-relative analysis on the three climatic factors of air temperature, pressureand relative humidity to the attack of acute myocardial infartion in Shenyang city located in the coldNortheastem China arca,showed that the attack was more frequent in summer time with high temperature,humidity and low air pressure. The attack was positively related to temperature(r=0. 7463 P＜0. 01) andhumidity (r=0. 6466 P＜0.01) while is negatively related to air pressure (r=-0. 7300 P＜0. 05).And speifically, in Shenyang arca the incidence was obviously increased with average temperature＞20℃,airpressure＜1010, and relative humidity ＞70%. Patients should reduce the activities in high or lowtemperature environment. Proper precautions should be taken well in advance to avoid the attack on thepatients in a particular scason. And different nursing measures should be taken in different seasons to complywith changes of climate, for averting the attacks caused by the climate.
