Cardiovascular diseases and stroke in African Americans: a call for action.

Considerable disparities in cardiovascular and stroke mortality and morbidity rates exist between African Americans and other Americans. Increased prevalence and severity of hypertension, with earlier onset and often inadequate therapy, seem to be the major culprits responsible for the differences. There are ominous signs indicating that our recent dramatic progress in the control of cardiovascular disease and stroke is slowing, and in certain areas (stroke incidence and prevalence, hypertensive end-stage renal disease) progress is actually regressing. It is urgent that renewed research and medical interventions be undertaken to address this crisis. The American Heart Association and the National Medical Association have these and many other goals in common. Concerted action by all concerned organizations is essential.
