Hypertensive Emergency

Hypertensive Emergency involves specific alterations in hypertensive emergency physiology. The pathophysiology of Hypertensive Emergency encompasses changes in myocardial contractility, cardiac conduction, vascular resistance, endothelial function, or structural integrity depending on the primary mechanism involved. Key cellular processes include ion channel dysfunction, inflammatory mediator activation, oxidative stress, fibrotic remodeling, and neurohormonal dysregulation that drive the clinical manifestations of hypertensive emergency.
