This study's aim was to elucidate the effects of statin treatment on coronary microvascular dysfunction and left ventricular remodeling in acute myocardial infarction (AMI) patients. METHODS: Thirty-five patients undergoing successful reperfusion following AMI were assigned to a statin-treated (Group S, 16) or a non-statin-treated (Group NS, 19) group, according to fasting serum low-density lipoprotein-cholesterol. (13)N-ammonia positron emission tomography was performed to assess myocardial flow reserve (MFR) in the infarct area. RESULTS: Infarct sizes and lipid profiles during the chronic period were similar between the two groups. At 2 weeks after AMI onset, mean MFR in the infarct area was significantly higher in Group S than in Group NS (2.34 ± 0.63 vs. 1.91 ± 0.43, p=0.0214). At 6 months post-AMI, Group S had a smaller left-ventricular end-diastolic volume index (69.4 ± 11.7 mL/m(2) vs. 88.5 ± 32.5 mL/m(2), p=0.0328) and higher left-ventricular ejection fraction (67.7 ± 9.2% vs. 59.2 ± 13.3%, p=0.0394) than Group NS. Serum asymmetric dimethylarginine was significantly increased in Group NS at 1 month post-AMI (0.43 ± 0.12 μmol/L (baseline) vs. 0.52 ± 0.14 μmol/L, p=0.0186), but unchanged in Group S. CONCLUSIONS: Statin treatment appears to beneficially attenuate left ventricular remodeling after AMI, which may be associated with restoring coronary endothelial function via endogenous nitric oxide.
