ma·lig·nant hy·per·ten·sion

severe hypertension that runs a rapid course, causing necrosis of arteriolar walls in kidney, retina, etc.; hemorrhages occur, and death most frequently is caused by uremia or rupture of a cerebral vessel.

malignant hypertension

the most lethal form of hypertension. It is a fulminating condition characterized by severely elevated blood pressure that commonly damages the intima of small vessels, the brain, the retina, the heart, and the kidneys. It affects more African-Americans than Caucasians and may be caused by a variety of factors, such as stress, genetic predisposition, obesity, use of tobacco, use of oral contraceptives, high intake of sodium, sedentary lifestyle, renal disease, and aging. Many patients with this condition exhibit signs of hypokalemia and alkalosis and have aldosterone secretion rates even higher than those associated with primary aldosteronism. Also called accelerated hypertension. See also essential hypertension.
