Implication
Informs first-line therapy selection and <140/90 targets in South African practice; extends consensus guidelines with tailored recommendations for black patients and resistant hypertension.
Key Points
- To establish evidence-based clinical recommendations for target blood pressure levels, cardiovascular risk evaluation, and stepwise antihypertensive drug therapy.
- Formulated by the Southern African Hypertension Society using evidence synthesized from randomized controlled trials.
- Outlined diagnostic protocols for standardized blood pressure measurement and overall cardiovascular disease risk stratification.
- Target blood pressure for standard antihypertensive management is systolic <140 mmHg and diastolic <90 mmHg, with stricter thresholds advised for patients with co-morbidities such as diabetes mellitus.
- First-line regimens for uncomplicated hypertension include low-dose thiazide-like diuretics, calcium channel blockers, or angiotensin-converting enzyme inhibitors, advising upfront combination therapy when blood pressure is ≥20/10 mmHg above target.
- Initial treatment in black patients prioritizes thiazide-like diuretics or calcium channel blockers over beta-blockers or angiotensin-converting enzyme inhibitors due to superior response rates.
Structured PICO
What are the recommendations for the evaluation and management of hypertension in South Africa?
P
Population
Patients with hypertension, including specific subgroups such as the elderly, black patients, and those with end-organ damage, co-existing risk factors, or diabetes mellitus.
I
Intervention
Antihypertensive management including lifestyle modification and stepwise pharmacological therapy (low-dose thiazide-like diuretics, calcium channel blockers, ACE inhibitors, or ARBs).
O
Outcome
Target blood pressure <140/90 mmHg (stricter for patients with end-organ damage or diabetes).
The 2011 South African hypertension guideline provides comprehensive recommendations for blood pressure measurement, cardiovascular risk evaluation, and stepwise antihypertensive therapy.
