Endothelial Growth Factor

1. Vascular endothelial growth factor, a potent angiogenic mitogen, is known to be induced in response to ischaemia as well as being secreted from tumour cells. However, the precise mechanism of vascular endothelial growth factor release in acute myocardial infarction and the effects of coronary reperfusion on the circulating levels of vascular endothelial growth factor are still unknown. 2. Nineteen patients with acute myocardial infarction who underwent early reperfusion therapy were studied. Serum levels of vascular endothelial growth factor before reperfusion were markedly increased as compared with those in 19 healthy control subjects [252.4 ± 158.1 pg/ml (mean ± SD) compared with undetectable]. After reperfusion, the serum vascular endothelial growth factor levels rapidly returned almost completely to the normal control range. 4. These data strongly suggest that the serum level of vascular endothelial growth factor is one of the most sensitive indicators of myocardial ischaemia.

Host Myocardium

Background Vascular endothelial growth factor (VEGF) is a promising reagent for inducing myocardial angiogenesis. Skeletal myoblast transplantation has been shown to improve cardiac function in chronic heart failure models by regenerating muscle. We hypothesized that transplantation of VEGF-expressing myoblasts could effectively treat acute myocardial infarction by providing VEGF-induced cardioprotection through vasodilatation in the early phase, followed by angiogenesis effects in salvaging ischemic host myocardium combined with the functional benefits of newly formed, skeletal myoblast-derived muscle in the later phase. Methods and Results Primary rat skeletal myoblasts were transfected with the human VEGF 165 gene using hemagglutinating virus of Japan-liposome with >95% transfection efficiency. Four million of these myoblasts (VEGF group), control-transfected myoblasts (control group), or medium only (medium group) was injected into syngeneic rat hearts 1 hour after left coronary artery occlusion. Myocardial VEGF-expression increased for 2 weeks in the VEGF group, resulting in enhanced angiogenesis without the formation of tumors. Grafted myoblasts had differentiated into multinucleated myotubes within host myocardium. Infarct size (33.3±1.4%, 38.1±1.4%, and 43.7±1.6% for VEGF, control, and medium groups, respectively; P =0.0005) was significantly reduced with VEGF treatment, and cardiac function improved in the VEGF group (maximum dP/dt: 4072.0±93.6, 3772.5±101.1, and 3482.5±90.6 mm Hg/s in the 3 groups, respectively; P =0.0011; minimum dP/dt: −504.2±68.5, −2311.3±57.0, and −2124.0±57.9 mm Hg/s, respectively; P =0.0008). Conclusions This combined strategy of cell transplantation with gene therapy could be of importance for the treatment of acute myocardial infarction.
