Abstract：Objective To examine the effects of intensive glucose control on myocardial tissue perfusion and ventricular function in post-percutaneous coronary intervention(PCI)diabetes mellitus(DM)patients with acute myocardial infarction(AMI).Methods Sixty-eight DM patients with AMl were divided into two groups:DM routine treatment group(n=34)and DM intensive treatment group(n=34),and 69 AMI patients with normal glucose tolerance(NGT)as NGT control group.DM routine treatment group were treated with novolin 30R.to maintain blood glucose in 8.0～11.1mmol/L;DM intensive treatment group were treated with insulin.and(or)insulin pump,to maintain blood glucose in 4.4-6.1 mmol/L.All patients underwent emergency coronary angiography after PCI.We estimated the myocardial tissue perfusion according to the myocardial blush grade(MBG).The left ventricular ejection fraetio(LVEF)and cardiac index(CI)were measured in all patients at 1 week and l month after PCI to estimate ventricular function.Resuits There was no significant difference in TIMI Grade 3 after PCI among three groups(P>0.05),and the percentage of efficient reperfusion in DM group was significantly lower than NCT control groups(64.7%,82.3%vs 94.2%,P<0.01).The CI value was much higher in NGT intensive treatment group than DM routine treatment group(P<0.01),and there was no significant difference between DM intensive treatment group and NGT control group at 1 week and 1 month after PCI(P>0.05),but the CI value was significandy improved in all three groups at 1 month than at 1 week after PCI(P<0.05).The LVEF was much higher in NGT control group than DM groups(P<0.01),and significandy improved in NGT control group and DM intensive treatment group at 1 month than at 1 week after PCI(P<0.05),but there was no significant improved in DM routine treatment group(P>0.05).Condusion Intensive glucose control may significantly improve myocardial tissue perfusion and ventricular function after PCI in DM patients with AMI.
