Hypertensive Emergency — Management Pathway

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Acute target-organ damage?
   Severe hypertension (often >180/120) with acute target-organ damage? (Target-organ damage: hypertensive encephalopathy, acute stroke, ACS, acute LV failure/pulmonary edema, aortic dissection, acute kidney injury, pre-eclampsia/eclampsia, papilledema. Damage present = hypertensive emergency; no damage = 'markedly elevated BP / urgency'.)
   • Target-organ damage (emergency) → Emergency · special situation?
   • No target-organ damage (urgency) → Urgency
2. [End] Urgency
   No acute target-organ damage: rapid IV lowering is not needed (lowering too fast is harmful). Restart or up-titrate oral antihypertensives, address triggers (pain, anxiety, missed medication), arrange outpatient reassessment. Avoid immediate-release nifedipine, IM antihypertensives, etc.
3. [Decision] Emergency · special situation?
   A special situation needing a faster / specific target? (Special situations have different targets: aortic dissection → SBP <120 within 20 min (control HR <60 with a beta-blocker first); pre-eclampsia/eclampsia → SBP <140 within 1 h (+ magnesium sulfate); pheochromocytoma crisis → alpha-blockade; acute ischemic stroke is managed by thrombolysis/thrombectomy thresholds separately.)
   • General hypertensive emergency → General hypertensive emergency
   • Special situation (dissection/eclampsia/pheo/stroke) → Special situation
4. [End] General hypertensive emergency
   ICU, titratable IV agents (nicardipine/labetalol/clevidipine/nitroprusside; nitroglycerin for pulmonary edema or ACS). Lower SBP by ≤25% in the first hour, then to 160/100–110 over 2–6 h, and cautiously to normal over 24–48 h. Avoid lowering too fast (cerebral/cardiac/renal hypoperfusion). Treat triggers.
5. [End] Special situation
   Manage rapidly to each target: aortic dissection SBP <120 and HR <60 within 20 min (beta-blocker ± vasodilator); pre-eclampsia/eclampsia SBP <140 within 1 h with magnesium sulfate; pheochromocytoma crisis with alpha-blockade (phentolamine; never a beta-blocker alone); acute ischemic stroke by reperfusion thresholds (<185/110 for thrombolysis) rather than the usual emergency target.
