Classification of HT (JNC – 7)+
Prevalence difficult to estimate
General population: Low
Specialized HT clinics: High
*Clinical trials +: 30-50%
*(ALLHAT, CONVINCE, LIFE, INSIGHT: BP not reduced to
target levels of >140/90 in 30-50%)
+ Reference 3
24 h Ambulatory BP Monitoring to Exclude White Coat Hypertension
+ Reference 4, 5, 6
K+, diabetes status
+Reference 2, 6
Renogram / scintigraphy
CT angio, MRA, DSA
Renal vein renin ratioInvestigations for Renal Artery Stenosis (RAS)+
Abbreviations: PRA=plasma renin activity, CT= computed tomography, MRA= magnetic resonance imaging, DSA= digital subtraction angiography
+ Reference 4, 6

Consult hypertension specialist
Treat correctable cause, if any (renal angioplasty,
Stenting+, surgery for phaeochromocytoma)
Aggressive drug therapy:
- Optimize existing drugs
- Add frusemide, aldosterone antagonist
- Hydralazine or minoxidil with betablocker
and a diuretic
- Clonidine (oral or transdermal)
- Combine ACE-I and ARB
- Renin inhibitors (aliskiren)
Intensify lifestyle modifications
