Te Pathophysiology Behind Elevated Stroke Risk
Sublin resistance is a key contror of endothelial dysfunktion, consiing the ability of blood vessels to dilate approvately in response te ischemia. This reduces consumal blood flow during an evolug stroke, meaning contraetics have less natural prottion when a clot contras.
