Therapy of hypertension in African Americans

Area of Science:

• Cardiology
• Nephrology
• Public Health

Background:

• Hypertension in African Americans presents a significant public health challenge due to high prevalence, early onset, and resistance to medication.
• Lower blood pressure (BP) control rates are observed in African Americans, particularly men (29.9% for non-Hispanic Black men), compared to other groups.
• Co-morbidities like obesity, diabetes, reduced kidney function, and albuminuria contribute to treatment resistance.

Purpose of the Study:

• To outline an optimal, comprehensive approach for managing hypertension in African Americans.
• To emphasize risk stratification and individualized goal BP levels for effective treatment.
• To highlight the necessity of combination antihypertensive drug therapy for achieving BP targets and protecting organs.

Main Methods:

• Risk stratification of patients with elevated blood pressure.
• Implementation of multifactorial lifestyle modifications (weight loss, reduced salt/alcohol intake, increased physical activity).
• Initiation of combination antihypertensive drug therapy when BP exceeds goal levels by >15/10 mmHg.

Main Results:

• The majority of African American hypertensive patients require combination therapy for sustained BP control.
• Preferred initial combination therapies include calcium channel blockers/angiotensin-converting enzyme inhibitors or thiazide diuretics/angiotensin-converting enzyme inhibitors for specific conditions.

Conclusions:

• A comprehensive strategy combining lifestyle changes and effective drug combinations is essential for managing hypertension in African Americans.
• Targeted combination therapies are critical for achieving blood pressure control and preventing target-organ damage in this high-risk population.
