The presence of the plaque induces the muscle cells of the blood vessel to stretch, compensating for the additional bulk. The endothelial lining then thickens, increasing the separation between the plaque and lumen. The thickening somewhat offsets the narrowing caused by the growth of the plaque, but moreover, it causes the wall to stiffen and become less compliant to stretching with each heartbeat.
