Abstract

Racial differences in the prevalence, course, and pathophysiologic characteristics of hypertension in black and white populations are reviewed. Accumulated epidemiologic data indicate that the prevalence of hypertension among blacks is greater than that among whites in almost all age- and sex-matched groups. Hypertensive blacks have a higher incidence of left ventricular dysfunction, stroke, and renal damage, but a lower incidence of ischemic heart disease, than do hypertensive whites. A significant pathophysiologic difference between blacks and whites is salt sensitivity; normotensive, as well as hypertensive, blacks tend to be salt sensitive. Blacks also tend to have lower renin levels than do whites, while dopamine response to a salt load is diminished among blacks as compared with whites. These differences and others lead to the recommendation that hypertension among blacks should be managed initially with salt restriction; if dietary control is insufficient, administration of an antihypertensive agent with 24-hour efficacy, which lowers vascular peripheral resistance, promotes sodium excretion, and potentially improves renal hemodynamics, is recommended. A calcium channel blocker may satisfy these requirements.
