Progenitor Cell Dysfunction: The Role of Endothelial Precursors in Heart Failure

Abstract

Heart failure (HF) a leading cause of premature death in patients with established cardiovascular (CV) disease. Although the global burden of HF is increasing, there is no evidence regarding promising results that improves longterm clinical outcomes especially for HF with preserved and mid-regional pump function. In this context, determination of the vulnerable populations at higher risk of HF development and progression is very promising. Endothelial dysfunction (ED) plays a central role in the manifestation of HF regardless its phenotypes. There is a large body of evidence regarding that the endothelial progenitor cells (EPCs) as a component of endogenous vascular repair system could be modified by several stimuli including epigenetic factors and thereby they are involved in the pathogenesis of ED. However, there is unclear whether EPC dysfunction is only whiteness of HF or it could be a factor of HF manifestation in vulnerable population. The short communication is depicted the uncertain role of EPC dysfunction in pathogenesis of HF.

“…Moreover, there is suggested that EPC dysfunction is not only result in etiology effect and co-morbidity influence, but it is independent predictor of HF advance and probably HF-related outcomes. Indeed, previously reported results of other studies provided by wide circle of investigators have shown that the EPCs can appear prior to asymptomatic HF and cooperate with numerous CV risk factors [9,10]. Therefore, EPC dysfunction reflects lowered ability of EPCs in survival, migration and differentiation and thereby it is confirmation a pivotal role of endogenous endothelial repair system in shaping maladaptive cardiac and vascular remodeling and HF development [11,12].…”
