Review of the major hypertension trials in the elderly

Abstract

The different intervention trials in elderly hypertensives are compatible with the hypothesis that hypotensive drug treatment can decrease cardiovascular mortality mainly by decreasing cerebrovascular mortality. A decrease in the fatal and nonfatal cardiovascular event rate is mainly due to a decrease in cerebrovascular events. It is not established whether hypotensive drug treatment is advisable in symptomless patients with isolated systolic hypertension and in patients with uncomplicated hypertension above age 80. A sudden reduction in blood pressure should be avoided, but whether a progressive reduction of systolic blood pressure below 140 mmHg and of diastolic blood pressure below 85 mmHg is dangerous or advantageous remains to be established.
