Blacks in the United States have disproportionately high rates of cardiovascular disease and mortality. Left ventricular hypertrophy, the primary manifestation of hypertensive heart disease and a major independent predictor of cardiovascular mortality, is twice as prevalent in Blacks with hypertension as in whites. Research has implicated chronic socio-environmental and psychological stress in the etiology of hypertension and left ventricular hypertrophy in Blacks. The trial seeks to investigate directly the impact of stress reduction programs for treating hypertensive heart disease in Blacks, since conventional antihypertensive drug therapies are less successful than expected. Moreover, these therapies frequently have adverse side effects on quality of life, and have low compliance rates, particularly in minorities.
