目的研究脉压(PP)是否与死亡有关,尤其是否与心、脑血管病有关。方法选择了1992-1993年,在韩国医疗保险公司投保年龄在40岁及以上的投保人,共有698796人,随访7年。随访开始时对每个观察对象进行健康检查并调查相关问题,随访期每2年进行1次查体。结果PP与全因死亡、心、脑血管病死亡有正相关关系。无论性别、年龄以及是否患有高血压,均得到相同结果,即随着PP升高,死亡危险性升高。但年龄越大,脉压的影响力度越弱。结论PP与全因死亡率、心脑血管病死亡率呈相关关系,在预测心脑血管病危险性时,PP可以作为一个独立的预测指标。
Objective To study whether pulse pressure (PP) is related to death, especially whether it is related to heart and cerebrovascular disease. Methods From 1992 to 1993, a total of 698,796 people insured Korean medical insurance companies aged 40 and above, with a total follow-up of 7 years. At the beginning of follow-up, each subject underwent health examination and investigation of relevant issues. The follow-up period was performed once every two years. Results PP and all-cause death, heart and cerebrovascular disease have a positive correlation. The same result was obtained irrespective of gender, age and whether or not suffering from high blood pressure, that is, the risk of death increased with increasing PP. However, the older, the weaker the impact of pulse pressure. Conclusions PP is related to all-cause mortality and cardiovascular and cerebrovascular disease mortality. PP can be used as an independent predictor in predicting the risk of cardiovascular and cerebrovascular diseases.
