Malignant essential hypertension

Malignant essential hypertension is an acute, life-threatening hypertensive emergency that arises from severe, idiopathic (primary) systemic high blood pressure It primarily affects the cardiovascular, renal, ocular, and central nervous systems, frequently presenting in adults with chronic or inadequately controlled underlying hypertension The defining clinical hallmark is extreme arterial blood pressure elevation—commonly exceeding a systolic pressure of 200 mm Hg or diastolic pressure of 120 t...

It primarily affects the cardiovascular, renal, ocular, and central nervous systems, frequently presenting in adults with chronic or inadequately controlled underlying hypertension Pathophysiologically, it is driven by a breakdown in vascular autoregulation and severe endothelial injury, leading to widespread arteriolar fibrinoid necrosis and microvascular ischemia The defining clinical hallmark is extreme arterial blood pressure elevation—commonly exceeding a systolic pressure of 200 mm Hg or d...

Pathophysiologically, it is driven by a breakdown in vascular autoregulation and severe endothelial injury, leading to widespread arteriolar fibrinoid necrosis and microvascular ischemia

The defining clinical hallmark is extreme arterial blood pressure elevation—commonly exceeding a systolic pressure of 200 mm Hg or diastolic pressure of 120 to 130 mm Hg—accompanied by advanced bilateral retinopathy (flame-shaped hemorrhages, cotton-wool exudates, or papilledema) and rapidly progressive target-organ damage such as acute kidney injury, hypertensive encephalopathy, or heart failure
