hypertension
n. high blood pressure: a circulatory disorder characterized by persistent arterial blood pressure that exceeds a standard, which usually is 140/90 mmHg. In the majority of cases, there is no obvious cause (see essential hypertension). In a few people, high blood pressure can be traced to a known cause, such as tumors of the adrenal gland, chronic kidney disease, hormone abnormalities, the use of oral contraceptives, or pregnancy. This is called secondary hypertension; it is usually cured if its cause is removed or is corrected. Malignant hypertension is a form of very high blood pressure that comes on quickly, usually accompanied by retinal hemorrhaging, and can result in organ damage if not immediately treated. Compare hypotension. —hypertensive
