Hypertension Management in African American Patients

Guideline-Based Treatment Algorithm

The International Society of Hypertension guidelines provide a clear stepwise approach specifically for Black patients with hypertension, recommending the addition of either a thiazide-like diuretic or an ARB/ACEI as the next antihypertensive agent for an African American patient on maximum dose amlodipine with uncontrolled hypertension 1, 2, 3, 4, 5, 6, 7, 8, 9
The American College of Cardiology/American Heart Association (ACC/AHA) 2017 guidelines specifically recommend that initial antihypertensive treatment in Black adults should include a thiazide-type diuretic or CCB 10

Thiazide-like diuretics (chlorthalidone, indapamide) are preferred over hydrochlorothiazide for superior cardiovascular outcomes 1, 2
ARBs are specifically mentioned in the ISH guidelines for Black patients at this step, and ACEIs have smaller blood pressure effects as monotherapy in Black patients, but remain effective when combined with CCBs 1, 2, 3, 4, 5, 10

Chlorthalidone 12.5-25 mg once daily, or indapamide 1.25-2.5 mg once daily, are recommended as a thiazide-like diuretic 1, 2, 3, 5

Verify medication adherence and confirm diagnosis with home or ambulatory BP monitoring before escalating therapy 1, 2, 3
Check for secondary hypertension if BP remains severely elevated or resistant 1, 2
Aim for BP <130/80 mmHg (or at minimum <140/90 mmHg) and achieve target within 3 months of treatment adjustment 1, 2, 3, 4, 5
Consider using single-pill combinations to improve adherence and simplify the regimen 1, 2, 3
