High concentration of C-type natriuretic peptide promotes VEGF-dependent vasculogenesis in the remodeled region of infarcted swine heart with preserv…

Vasculogenesis is a hallmark of myocardial restoration. Post-ischemic late remodeling is associated with pathology and function worsening. At the same time, neo-vasculogenesis helps function improving and requires the release of vascular endothelial growth factor type A (VEGF-A). The vasculogenic role of C-type natriuretic peptide (CNP), a cardiac paracrine hormone, is unknown in infarcted hearts with preserved left ventricular (LV) ejection fraction (EF). We explored whether myocardial VEGF-dependent vasculogenesis is affected by CNP.To this end, infarcted swine hearts were investigated by magnetic resonance imaging (MRI), histological and molecular assays. At the fourth week, MRI showed t…
