| pubmed-article:1946790 | pubmed:abstractText | The major differences that have been recognized between black and white hypertensives are primarily epidemiologic, with hypertension being more prevalent, having an earlier onset, and having more severe sequelae in the black population. The cause of the problem in both black and white people remains obscure, but it appears that a difference in sodium handling may contribute to the particular hemodynamic and hormonal profile of black hypertensives. Salt sensitivity, expanded plasma volume and low renin levels have been the hallmark of the black hypertensive. Complications such as stroke and left ventricular hypertrophy remain the major sequelae of this disease in blacks. Finally, a current study confirmed the improved efficacy of antihypertensive therapy in blacks to diuretics and calcium channel blockers and a somewhat lower efficacy profile to angiotensin converting enzyme inhibitors and beta blockers, although the latter classes of agents have shown better response in blacks than previously thought. | lld:pubmed |
