Analysis of association between acute onset of coronary heart disease, stroke and meteorological factors, including temperature, atmospheric pressure, relative humidity etc, was done by simple correlation and multiple stepwise regression analysis, for a period of 2 years, 1984 to 1985. This study covered a population approximately of 700,000, scattered in defined areas of Beijing. The result showed that there was a negative correlation between incidence of stroke and acute myocardial infarction and some meteorological factors, such as temperature and clouds. A negative correlation between coronary sudden death and temperature had been observed by simple correlation analysis.
1984年至1985年期间，通过简单相关分析和多元逐步回归分析，对冠心病急性发作、中风与气象因素（包括温度、气压、相对湿度等）之间的关联进行了分析。本研究涵盖了分布在北京特定区域的约70万人口。结果显示，中风和急性心肌梗死的发病率与一些气象因素（如温度和云量）之间呈负相关。通过简单相关分析观察到冠心病猝死与温度之间呈负相关。
