Hypertensive crisis

A hypertensive crisis is an acute, severe elevation in blood pressure, classically defined as a systolic blood pressure exceeding 180 mm Hg and/or a diastolic blood pressure exceeding 120 mm Hg The condition is clinically stratified into hypertensive urgency, characterized by severe blood pressure elevation without acute end-organ dysfunction, and hypertensive emergency, marked by concurrent, life-threatening target-organ injury such as encephalopathy, acute coronary syndrome, aortic dissection,...

This clinical state affects the systemic vasculature and poses immediate risk to vital organ systems, most notably the central nervous system, cardiovascular system, and kidneys Pathophysiologically, the abrupt rise in systemic vascular resistance overwhelms normal vascular autoregulation, precipitating endothelial damage, microvascular thrombosis, and tissue ischemia The condition is clinically stratified into hypertensive urgency, characterized by severe blood pressure elevation without acute ...
