The association of hypertension, hypertension duration, and control with incident heart failure in black and white adults.

Associations between hypertension and some cardiovascular diseases are stronger in black vs white adults. We examined associations of hypertension, hypertension duration, and control with incident heart failure (HF) in black and white REasons for Geographic And Racial Differences in Stroke study participants (n = 25 770) who were followed for incident HF hospitalization (n = 947) from enrollment in 2003-2007 through 2015.
