Perivascular Fat

Perivascular fat refers to the layer of fat surrounding blood vessels, particularly arteries. While once thought to be just cushioning, this fat actively participates in vascular health by releasing molecules that influence blood vessel function and inflammation. Excess or unhealthy perivascular fat can contribute to the development of atherosclerosis, a condition where arteries become narrowed or hardened, increasing the risk of heart disease. Its role as both a marker and a contributor to cardiovascular risk makes it an important focus in understanding and managing vascular health.
