Systolic hypertension: occurrence and treatment in a defined community.

Systolic hypertension, a disorder occurring predominantly in the elderly, is associated with an increased incidence of stroke and coronary artery disease. Based on the supposition that it is a risk factor, many authorities have urged that it be treated. This report concerns an experience in treating systolic hypertension in a defined ambulatory population of 898 hypertensive subjects in a work-site program. The systolic hypertension group (N = 39) was compared with a matched diastolic hypertension group and with a matched systolic/diastolic hypertension group (N = 39 each). The patients with systolic hypertension responded to standard treatment (chiefly with diuretics), but less satisfactorily than did the patients with diastolic hypertension. Side effects or toxicity were uncommon and did not interfere with the therapeutic regimen. However, the ultimate value of such therapy in the prevention of vascular complications remains to be determined.
