心血管疾病是包括我国在内的许多国家最常见的死亡原因。只有弄清其原因,才有可能降低这种高死亡率。现时开展的预防运动皆集中注意于控制吸烟,高血压和高脂血症,但这些危险因素至多只占所有心肌梗塞原因的一半。在许多温带国家,冬季冠心病死亡率和住院率比夏季高,在某些冬季,冠心病死亡率比夏季高7Q％。冬季冠心病死亡率高出的程度与环境温度不同有联系。在气温变化范围宽且冬季较冷的国家和地区,冠心病发作的季节性波动较大,而在室内气温比较恒定的国家和地区,季节性波动较小。在英国,住宅采暖设备不良的穷人冬季冠
Cardiovascular disease is the most common cause of death in many countries, including my country. It is possible to reduce this high mortality rate only by clarifying its causes. At present, preventive campaigns are focused on controlling smoking, high blood pressure and hyperlipidemia. However, these risk factors account for up to half of all the causes of myocardial infarction. In many temperate countries, winter coronary heart disease mortality and hospitalization rates are higher than in summer, and in some winter months, coronary heart disease mortality is 7% higher than in summer. The higher the mortality rate of coronary heart disease in winter is related to the difference of the ambient temperature. In countries and regions with wide temperature range and colder winter, the seasonal fluctuation of coronary heart disease is larger, while in the countries and regions where indoor air temperature is relatively constant, the seasonal fluctuation is relatively small. In the UK, poor winter heating of residential heating equipment crowns
