摘要: Objectives We analyzed the molecular mechanisms evoked by tight glycemic control during post-infarction remodeling in human hearts. Background The which improves heart acute myocardial infarction (AMI) are still largely unknown. Methods Eighty-eight patients with first AMI undergoing coronary bypass surgery were studied: 38 normoglycemic served as group; hyperglycemic (glucose ≥140 mg/dl) randomized to intensive (IGC) (n = 25; glucose 80 140 or conventional (CGC) 180 200 for almost 3 days before surgery, insulin infusion followed subcutaneous treatment. Echocardiographic parameters investigated at admission and after treatment period. During oxidative stress (nitrotyrosine, superoxide anion [O2–] production, inducible nitric oxide synthase [iNOS]), inflammation (nuclear factor kappa B [NFκB], tumor necrosis [TNF]-α, apoptosis (caspase-3) biopsy specimens taken from peri-infarcted area. Results Compared patients, had higher performance index (MPI) (p Conclusions Tight control, reducing inflammation, might reduce areas patients.
