A hypertensive emergency (formerly called "malignant hypertension") is severe hypertension (high blood pressure) with acute impairment of one or more organ systems (especially the central nervous system, cardiovascular system and/or the renal system) that can result in irreversible organ damage. In a hypertensive emergency, the blood pressure should be substantially lowered over a period of minutes to hours with an antihypertensive agent.

Famous quotes containing the word emergency:
“War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.”
—Susan Sontag (b. 1933)
