Effect of atorvastatin combined with routine therapy on the expression of hypoxia inducible factor (HIF‑1) and vascular endothelial growth factor (VEGF) in rats with acute myocardial infarction (AMI) and its therapeutic effect were investigated. The rat models of acute myocardial infarction were established and divided into routine therapy, study, model, single drug and control group according to the treatment plan, with 10 cases in each group. Enzyme‑linked immunosorbent assay (ELISA) was used to detect the concentration of HIF‑1 and VEGF in serum of rats before treatment (T0), and 3 days (T1), 5 days (T2) and 7 days (T3) after treatment, and the cardiac function was measured at the same time. The concentrations of HIF‑1 and VEGF in serum of the study group and the routine therapy group after treatment were significantly higher than those before treatment. The concentrations of HIF‑1 and VEGF in serum of model group at T0 were significantly lower than those at T3 (P<0.05). After treatment, the concentrations of HIF‑1 and VEGF in serum of the study group were significantly higher than those of the routine therapy, the model and the control group (P<0.05). One week after administration, there were significant differences in the left ventricular function among the five groups (P<0.001). The left ventricular function in the study group was better than that in the routine therapy, model and control group. The levels of HIF‑1 and VEGF in the serum of rats with myocardial infarction were negatively correlated with LVIDs and LVIDd, and positively correlated with LVEF% and LVFS%. In conclusion, atorvastatin combined with routine therapy can better reduce serum HIF‑1 and VEGF levels and improve the left ventricular function in rats than routine therapy.
