Impaired Pattern of Endothelial Derived Microparticles in Heart Failure Patients

Abstract

Alexander E Berezin

Chronic heart failure (CHF) remains a leading cause of cardiovascular morbidity and mortality worldwide that is characterized pandemic features. Metabolic diseases, neurohumoral state, and systemic inflammatory response are considered the origin of microvascular endothelial cell inflammation that leads to development of CHF and supporting cardiac remodelling and vascular dysfunction. Endothelial-derived microparticles (EMPs) are considered a novel biological marker of endothelial injury and vascular tone disorders. Biological effect of EMPs realizes through supporting of cell-to-cell cross-talking mediated by transport microRNA, active molecules, hormones, peptides, regulator proteins, etc. EMPs derived from activated endothelial cells may play a pivotal role in the vascular remodelling and endothelial reparation. In opposite, EMPs originated from apoptotic endothelial cells are considered a direct trigger of vascular injury. The review is addressed to discussion of one of possible mechanism of effect realizing of endothelial-derived microparticles different origin in heart failure affected endogenous reparation and tissue injury.
