- Abstract
Vascular endothelial growth factor (VEGF) is a growth factor for vascular endothelial cells in vitro. The present study was designed to determine whether serum VEGF levels increase in patients with acute myocardial infarction (AMI) compared with patients with stable exertional angina and control subjects, and to examine the serial changes of serum VEGF levels in patients with AMI. We examined serum VEGF levels by using antibody prepared from serum immunized with human VEGF[sub 121] . The serum VEGF level (pg/ml) was higher (p < 0.0001) on admission in the patients with AMI (177 ± 19) than in those with stable exertional angina (61 ± 7) and control subjects (62 ± 6). The serum VEGF level (pg/ml) of the patients with AMI was 177 ± 19 on admission, 125 ± 9 on day 3, 137 ± 11 on day 5, 242 ± 18 at 1 week, and 258 ± 22 at 2 weeks after admission. The value was higher on admission than on day 3 after admission (p = 0.014), the values were higher at 1 week and 2 weeks than on admission, on day 3, and 5 (p < 0.01). Furthermore, there were correlations between peak VEGF levels at 1 week or 2 weeks after admission and peak creatine kinase levels. The increase of VEGF on admission in the patients with AMI may be due to the hypoxia of acute myocardial ischemia. The elevation at 1 week and 2 weeks from the onset may cause the development of collateral circulation in relation to the healing of the infarction site.Copyright © 2000 S. Karger AG, Basel
