Key high-yield points
- Secondary hypertension = ~10% of all hypertension; remaining 90% is essential (primary)
- Suspect secondary cause in: young patients, resistant hypertension (BP above target despite 3 agents at optimal doses, one a diuretic), biochemical abnormalities (especially hypokalaemia), no family history
Primary hyperaldosteronism is the most common secondary cause of hypertension in hypertensive clinic populations (~5-10%). Always consider it in young patients with resistant hypertension - even with normal potassium.
