In addition, hypertension precedes heart failure in 90% of cases, [7] and the majority of heart failure in the elderly may be attributable to hypertension. [17] Hypertensive heart disease was estimated to be responsible for 1.0 million deaths worldwide in 2004 (or approximately 1.7% of all deaths globally), and was ranked 13th in the leading ...
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.

Commonly, ischemic heart attack and stroke are the causes that lead to death in patients with severe hypertension. It is estimated that for every 20 mm Hg systolic or 10 mm Hg diastolic increase in blood pressures above 115/75 mm Hg, the mortality rate for both ischemic heart disease, cancer and stroke doubles.

Autonomic dysreflexia (AD) is a potentially fatal medical emergency classically characterized by uncontrolled hypertension and cardiac arrhythmia. [2] [3] [4] AD occurs most often in individuals with spinal cord injuries with lesions at or above the T6 spinal cord level, although it has been reported in patients with lesions as low as T10. [5]
An analysis of data from more than 18,000 patients with high blood pressure found that the proportion with uncontrolled hypertension had increased by 10 percent in 2017-18, compared to 2013 to ...
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]
Severely elevated blood pressure (equal to or greater than 180 mmHg systolic or 120 mmHg diastolic) is referred to as a hypertensive crisis (sometimes termed malignant or accelerated hypertension), due to the high risk of complications.
The prevalence of labile hypertension in USA is estimated to have more than 40 million adults which can develop the risks of hemorrhagic stroke. [15] Labile hypertension is most common in Charlottesville, Virginia with up to 11% of the population. Average age who have labile hypertension is 64±13 years. [16]
