Hypertension in the emergency department

Abstract

Hypertensive emergencies are now rare and are recognized by the deleterious effect on end-organs. Prompt, efficacious treatment is critical, and the current drug of choice for most episodes is sodium nitroprusside. Hypertensive urgencies are more common than are emergencies, and are distinguished by diastolic pressures greater than 115 mm Hg without end-organ dysfunction. Although there are many efficacious agents, one excellent choice is nifedipine.
