Implication
Confirms longstanding hypertension disparities in African Americans; leaves open effective strategies to close the control gap.
Key Points
- To review the epidemiologic burden, clinical severity, and control rates of hypertension and associated cardiovascular complications in African Americans.
- Synthesized epidemiological data on the prevalence, age of onset, and target-organ complications of hypertension among African Americans.
- Evaluated population blood pressure control rates below 140/90 mm Hg across untreated and pharmacologically treated cohorts.
- Hypertension accounts for approximately 30% of all mortality in African Americans and presents with earlier onset, greater severity, and higher rates of left ventricular hypertrophy than in white Americans.
- Only 25% of all African Americans with hypertension and fewer than 50% of those receiving antihypertensive medication achieve target blood pressure control (<140/90 mm Hg).
