South African Hypertension Practice Guideline 2014 : Review Article

ABSTRACT

Outcomes: Extensive data from many randomised; controlled trials have shown the benefit of treating hypertension (HTN). The target blood pressure (BP) for antihypertensive management is systolic 140 mmHg and diastolic 90 mmHg; with minimal or no drug side effects. Lower targets are no longer recommended. The reduction of BP in the elderly should be achieved gradually over one month. Co-existent cardiovascular (CV) risk factors should also be controlled. Benefits Reduction in risk of stroke; cardiac failure; chronic kidney disease and coronary artery disease. Recommendations: Correct BP measurement procedure is described. Evaluation of cardiovascular risk factors and recommendations for antihypertensive therapy are stipulated. Lifestyle modification and patient education are cornerstones of management. The major indications; precautions and contra-indications are listed for each antihypertensive drug recommended. Drug therapy for the patient with uncomplicated HTN is either mono- or combination therapy with a low-dose diuretic; calcium channel blocker (CCB) and an ACE inhibitor (ACEI) or angiotensin receptor blocker (ARB). Combination therapy should be considered ab initio if the BP is ? 160/100 mmHg. In black patients; either a diuretic and/or a CCB is recommended initially because the response rate is better compared to an ACEI. In resistant hypertension; add an alpha-blocker; spironolactone; vasodilator or ?-blocker
