Pathophysiology of Hypertension | Circulation Research
Apr 1, 2021 · Primary (or essential) hypertension represents between 85% and 95% of human cases and has an unidentified cause. In contrast, secondary hypertension is caused by identifiable underlying conditions, including renal artery stenosis, pheochromocytoma, adrenal adenoma, or single-gene mutations.

High blood pressure (hypertension) - Symptoms & causes
Feb 29, 2024 · Blood pressure is measured in millimeters of mercury (mm Hg). In general, hypertension is a blood pressure reading of 130/80 millimeters of mercury (mm Hg) or higher. The American College of Cardiology and the American Heart Association divide blood pressure into four general categories.

Aug 28, 2023 · Hypertensive urgency describes a blood pressure greater than 180/120 mmHg and hypertensive emergency refers to a very high blood pressure that results in potentially life-threatening symptoms and end-organ damage. [3] . Hypotension, on the other hand, is a blood pressure less than 90/60 mmHg. [4] .

Abstract. Despite major advances in understanding the pathophysiology of hypertension and availability of effective and safe antihypertensive drugs, suboptimal blood pressure (BP) control is still the most important risk factor for cardiovascular mortality and is globally responsible for more than 7 million deaths annually.

Hypertension: pathophysiology and treatment | BJA Education
Jun 1, 2004 · Pathophysiology. Hypertension is a chronic elevation of blood pressure that, in the long-term, causes end-organ damage and results in increased morbidity and mortality. Blood pressure is the product of cardiac output and systemic vascular resistance.
PATHOPHYSIOLOGICAL/HISTORICAL CONCEPTS. The elusive nature of primary hypertension and the pre-cise mechanisms underlying an elevation of blood pres-sure (BP), even in cases of secondary hypertension and in models of experimental hypertension, have remained a focus of debate and research for more than a cen-tury.
CHAPTER 24: PATHOPHYSIOLOGY OF HYPERTENSION
The pathophysiology of hypertension involves the impairment of renal pressure natriuresis, the feedback system in which high blood pressure induces an increase in sodium and water excretion by the kidney that leads to a reduction of the blood pressure.
