Hypertensive crisis; Other names: Malignant hypertension, accelerated hypertension: A systolic hypertensive crisis as measured on a home automated arm blood pressure monitor, showing an extremely elevated systolic blood pressure of 227, a mildly elevated diastolic blood pressure of 93 and a very fast tachycardic heart rate of 162 beats per minute.
Essential hypertension (also called primary hypertension, or idiopathic hypertension) is a form of hypertension without an identifiable physiologic cause. [1] [2] It is the most common type affecting 85% of those with high blood pressure. [3] [4] The remaining 15% is accounted for by various causes of secondary hypertension. [3]
Both of these definitions had collectively been known as malignant hypertension, although this medical term is replaced. [ citation needed ] In the pregnant patient, the definition of hypertensive emergency (likely secondary to pre-eclampsia or eclampsia) is only a blood pressure exceeding 160 mmHg systolic blood pressure or 110 mmHg diastolic ...
Not much is known about the epidemiology of hypertensive urgencies. Retrospective analysis of data from 1,290,804 adults admitted to hospital emergency departments in United States from 2005 through 2007 found that severe hypertension with a systolic blood pressure ≥180 mmHg occurred in 13.8% of patients.

Hypertension is a very common condition, affecting about half of all adults in the U.S. But it doesn’t always have symptoms, so about one in three people don’t know they have it.
Hypertension is slightly more frequent in men. [10] In people aged under 50 years, more men than women have hypertension, [10] and in ages above 50 years the prevalence of hypertension is the same in men and women. [10] In ages above 65 years, more women than men have hypertension. [7] Hypertension becomes more common with age. [5]
Because better methods for the control of blood pressure are now available in the general population, malignant hypertension is rarely seen. In contrast, other retinal vascular complications of hypertension, such as macroaneurysms and branch-vein occlusions, are not uncommon in patients with chronically elevated blood pressure. These stages of ...
