MACE-free survival rates among the two groups. The MACE-free survival rate of patients with acute myocardial infarction was significantly higher in the H group compared with that in the L group, when the follow-up was longer than 6 months. MACE, major adverse cardiovascular events; AMI, acute myocardial infarction; L group, ≤190 pg/ml VEGF plasma level; H group, >190 pg/ml VEGF plasma level; VEGF, vascular endothelial growth factor.
