《New Engl Med J》1983;309(20):1246. 在75岁以上的男女老人中,仅有收缩期高血压(收缩压160mmHg以上,舒张压90mmHg以下)者约占25—30％。收缩压和舒张压均升高的老年病人经治疗后虽已确证可减少死于心血管病的危险,但对于单纯的高收缩压进行治疗是否可减少危险性,目前不明。过去一般认为单纯收缩期高血压不必治疗,这种看法 New Engl Med J 1983; 309 (20): 1246. Of men and women aged 75 years and older, only 25-30% of those with systolic hypertension (systolic blood pressure 160 mmHg or greater and diastolic blood pressure 90 mmHg or less). Although elderly patients with elevated systolic and diastolic blood pressures have been shown to reduce the risk of dying from cardiovascular disease after treatment, it is not known whether treatment of simple high systolic blood pressure can reduce the risk. In the past generally considered isolated systolic hypertension do not have to treat this view
