AbstractHypertension in blacks differs in a quantitative sense from hypertension in whites; it occurs in blacks with greater frequency and severity and at a younger age when compared with whites. In addition, elevated blood pressure at any level is associated with increased cardiovascular morbidity and mortality in black patients. Several mechanisms have been suggested to account for this form of hypertension, implying that hypertension in black patients is intrinsically different from that in whites. Although these mechanisms remain unproven, it has generally been accepted that correctable renovascular disease and renovascular hypertension (RVH) occur infrequently in blacks; the authors, however, will review preliminary population-based data which suggest that the presence of renal artery disease is not determined by race or ethnicity. In addition, the prevalence of renovascular disease in a large group of consecutive hypertensive subjects will be presented. Finally, the blood pressure and renal function response after surgical renal artery repair in blacks will be compared with whites treated at the authors' institution. Taken collectively, these data and clinical experience support the search for and treatment of renal artery disease in properly selected hypertensive blacks.
