ISOLATED SYSTOLIC HYPERTENSION IN 14 COMMUNITIES1

Abstract
In the Hypertension Detection and Follow-up Program, 158,906 individuals from 14 communities around the United States had their blood pressure measured in their homes in 1972–1973. Of the total population screened, 2.4% had isolated systolic hypertension (systolic blood pressure ≥160 mmHg and diastolic blood pressure p ≤ 0.05). Isolated systolic hypertension is both relatively common and a significant risk factor for subsequent mortality.
