The Role of Cell-derived Microparticles in Cardiovascular Diseases: Current Concepts.

Cardiovascular disease remains the main cause of human morbidity and mortality in developed countries. Microparticles (MPs) are small vesicles originating from the cell membrane as a result of various stimuli and particularly of biological processes that constitute the pathophysiology of atherosclerosis, such as endothelial damage. They form vesicles that can transfer various molecules and signals to remote target cells without direct cell-to-cell interaction. Circulating microparticles have been associated with cardiovascular diseases. Therefore, many studies have been designed to further investigate the role of microparticles as biomarkers for diagnosis, prognosis, and disease monitoring. To this concept, the pro-thrombotic and atherogenic potential of platelets and endothelial-derived MPs have gained research interest, especially concerning accelerated atherosclerosis and triggering as well as prognosis of an acute coronary syndrome. MPs, especially those of endothelial origin, have been investigated in different clinical scenarios of heart failure and in association with left ventricular loading conditions. Finally, most cardiovascular risk factors present unique features in the circulating MPs population, highlighting their pathophysiologic link to cardiovascular disease progression. In this review article, we present a synopsis of the biogenesis and characteristics of microparticles, as well as the most recent data concerning their implication in cardiovascular settings.
