Definition of Hypertensive crisis
Hypertensive crisis: A
severe and potentially life-threatening increase in blood pressure
. A
hypertensive crisis is a medical emergency. When the blood pressure rises to
levels of 180/110 or greater, the blood vessels and organs may become damaged.
This damage can be manifested as a number of conditions including stroke, heart
attack, pulmonary edema (fluid in the lungs), a tear in the main artery of the body, the aorta (known as an
aortic dissection), and eclampsia (during pregnancy).
Symptoms of a hypertensive crisis can include the
symptoms typical for a stroke or heart attack; difficulty breathing, changes in
mental status, and severe headache may also occur. Immediate medical attention
is required for a severe increase in blood pressure. Treatment can involve
hospitalization and the use of oral and/or intravenous
medications.
