Platelet-derived vesicles: diagnostic and predictive value in cardiovascular diseases

Abstract

There is emerging evidence that endogenous microvesicles released by platelets may play a pivotal role in pathogenesis of numerous diseases including stable and unstable ischemic heart disease, atherosclerosis, hypertension, idiopathic pulmonary hypertension, atrial fibrillation/flutter, acute and chronic heart failure, as well as systemic vasculitis, systemic lupus erythematosus, antiphospholipid syndrome, transplant rejection, diabetes-induced angiopathy. Microvesicles that leased from the platelets exist as cargo for a large of number biological-active molecules including regulatory peptides, hormones, growth factors, active molecules coordinating cell-to-cell cooperation. Moreover, platelet-derived microvesicles are concerned about a conspicuous component in regulating angiogenesis, cardiac protection, and vascular repair. Recent animal and clinical studies have shown that the number of circulating platelet-derived microvesicles may sufficiently increase in accelerating atherosclerosis, acute atherothrombotic events, i.e., recurrent ischemia, myocardial infarction, thrombosis, hypertension, and stroke, microvascular inflammation. It is suggested that exaggerating levels of circulating platelet-derived microvesicles is strongly associated with endothelial dysfunction. The review is discussed the role of platelet-derived vesicles in the pathogenesis of the cardiovascular disease, as well as diagnostic and predictive capabilities of platelet-derived vesicles as biomarkers of a natural evolution of the diseases.
