Role of circulating vascular endothelial growth factor and hepatocyte growth factor in patients with coronary artery disease.
Vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) are thought to stimulate endothelial cell proliferation and induce angiogenesis in vivo. However. the precise mechanism responsible for VEGF and HGF release in patients with coronary artery disease is still unknown. We studied serum concentrations of VEGF and HGF in 20 patients with acute myocardial infarction (AMI), 20 patients with stable angina pectoris (AP) who had reversible perfusion defects on stress myocardial scintigraphy, and 16 patients with old myocardial infarction (OMI) who had no reversible defects on stress myocardial scintigraphy. The control group consisted of 20 patients with atypical chest pain who had angiographically normal coronary arteries. Serum VEGF and HGF concentrations were measured by enzyme-linked immunosorbent assay. Both the serum VEGF and HGF concentrations in the early stage of myocardial infarction in the patients with AMI were higher than those in the patients with AP and with OMI, and control patients. The VEGF concentration in the patients with AP was higher than in the patients with OMI, whereas the HGF concentration did not differ in the patients with AP and OMI. The VEGF concentration in AMI patients who had had preinfarction angina on admission was higher than that of patients who had had no preinfarction angina, whereas the HGF concentration did not differ between the two groups of patients. These results suggest that the serum VEGF concentration may reflect myocardial ischemia to a greater degree than the serum HGF concentration.
