Atherosclerosis is a prolonged process in which interaction of lipids and the haemostatic system produces focal lesions at sites of turbulence in arteries. Venous thromboembolism, ie, venous thrombosis and pulmonary embolism, represents a serious and poten­ tially fatal complication for many sick, hospitalized patients, especially those who are bedridden for extended periods of EVs can be released by every cell type and they can be classified into three major groups according to their biogenesis, dimension, density, and predominant protein markers: exosomes, microvesicles, and apoptotic bodies.
