Pathophysiology of hypertension - Wikipedia
The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...

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 …
Hypertension (HTN), defined as systolic blood pressure (SBP) > 140 mmHg or diastolic blood pressure (DBP) > 90 mmHg, is a major growing health problem across the globe [1-5]. It is the most common risk factor for cardiovascular disease and affects nearly two-thirds of adults aged 60 years or older [1,2].

Pathophysiology of Hypertension - SpringerLink
Since the mean arterial blood pressure (MAP) is a function of cardiac output (CO) and systemic vascular resistance (SVR), hypertension is fundamentally a hemodynamic disorder indicating a disturbance in CO and/or SVR. CO is a function of stroke volume (SV) and heart rate (HR).
Pathophysiology of hypertension - Oxford Academic
Blood pressure is determined by cardiac output and vascular resistance. This chapter explains how renal, cardiac, and vascular mechanisms interact to maintain blood pressure and organ perfusion. In pathophysiological situations, these systems …
