Pathophysiology of Hypertension
Regulation of Blood Pressure: Normal Physiology
Blood pressure regulation is a complex physiological process involving multiple systems...
Key Factors in Blood Pressure Regulation
- Cardiac Output: The heart's ability to pump blood effectively.
- Peripheral Resistance: The resistance of blood flow in vessels.
- Renal Function: The role of kidneys in fluid and electrolyte balance.
- Endocrine Influence: Hormones like aldosterone and catecholamines affect vascular tone.
Hypertension: A Breakdown
Hypertension occurs when blood pressure remains consistently elevated...
Pathophysiological Mechanisms
- Increased sympathetic nervous system activity
- Renin-Angiotensin-Aldosterone System (RAAS) dysregulation
- Endothelial dysfunction
- Genetic predisposition
Clinical Implications
Uncontrolled hypertension can lead to cardiovascular diseases, renal failure, and neurological complications...
