UNTREATED MILD HYPERTENSION: A Report by the Management Committee of the Australian Therapeutic Trial in Mild Hypertension

Abstract

In all subjects of the Australian therapeutic trial in mild hypertension, mean pressures for the two screening visits were within the range 95-109 mm Hg for diastolic blood-pressure phase V (DBP) and <200 mm Hg for systolic blood-pressure (SBP). In the 1943 control (placebo) subjects mean blood-pressures fell from 158/102 mm Hg at the first screening visit to 144/91 mm Hg 3 years later. At that time pressures remained within the mild hypertension range in 32%, had risen above it in 12%, and had fallen below in 48%. Trial end-points (ischaemic heart
