Additional notes (from the other “Hypertension” page)

Secondary hypertension highlights

• Primary hyperaldosteronism is a common cause in adults.
• In children, a common cause is fibromuscular dysplasia.
  • “String of beads” on angiogram.
• Renovascular hypertension red flags:
  • creatinine rise >30% after starting ACEi/ARB
  • recurrent flash pulmonary oedema
  • diffuse atherosclerosis
  • onset after age 55
  • asymmetric kidney size
  • abdominal bruit

Mineralocorticoid patterns (hypokalaemia)

• Aldosterone high + renin suppressed (high ratio) → primary hyperaldosteronism.
• Renin low + aldosterone low → consider Cushing syndrome or liquorice.

Hypertensive emergency

High BP + end-organ damage.

• initial IV options: labetalol or nitroprusside (with close monitoring).
