[The effect of climatic factors on the onset of acute myocardial infarction].
The results of the single-relative analysis on the three climatic factors of air temperature, pressure and relative humidity to the attack of acute myocardial infarction in Shenyang city located in the cold Northeastern China area, 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) and humidity (r = 0.6466 P < 0.01) while is negatively related to air pressure (r = -0.7300 P < 0.05). And specifically, in Shenyang area the incidence was obviously increased with average temperature > 20 degrees C, air pressure < 1010, and relative humidity > 70%. Patients should reduce the activities in high or low temperature environment. Proper precautions should be taken well in advance to avoid the attack on the patients in a particular season. And different nursing measures should be taken in different seasons to comply with changes of climate, for averting the attacks caused by the climate.
