Hypertension: A Systematic and Comprehensive Review

Hypertension, commonly referred to as high blood pressure, is a critical global health issue, contributing significantly to cardiovascular disease morbidity and mortality. Despite advancements in diagnosis and treatment, hypertension remains a major risk factor for heart attacks, strokes, and kidney diseases. This manuscript provides a comprehensive analysis of hypertension, covering its epidemiology, pathophysiology, diagnostic criteria, treatment options, and management strategies. Additionally, it explores the impact of lifestyle modifications, pharmacological interventions, and emerging therapies in managing hypertension. This resource aims to equip healthcare professionals and researchers with a thorough understanding of hypertension to improve patient outcomes. The etiology of hypertension involves a complex interplay of environmental and pathophysiological factors alongside genetics, diet, lifestyle, and other coexisting medical conditions. Treatment typically involves medication and lifestyle adjustments such as dietary changes, regular exercise, weight management, and stress reduction to pharmacological interventions involving drugs like diuretics, beta-blockers & ACE inhibitors to lower blood pressure. The pathogenesis of hypertension is linked to endothelial dysfunction, vascular remodelling, sympathetic nervous system activation, and the renin-angiotensin-aldosterone system. Diagnosis is made by measuring blood pressure using a sphygmomanometer, with stages including pre hypertension, stage 1 hypertension, and stage 2 hypertension. Effective management of hypertension requires lifestyle modifications such as dietary changes, regular exercise, weight control, and reduced alcohol consumption, alongside pharmacological interventions. As hypertension continues to be a leading cause of death and disability globally, understanding and addressing these factors are crucial for mitigating the widespread impact of hypertension on public health.
