average 67 years) -in the MG, 63±8 (65 years on average) -in the CG.Men had 67% MG vs. 62% CG.Diabetes mellitus: 7% -in the MG, 9% -in the CG.Regional hypothermia was performed by an intracoronary solution of 0.9% NaCl cooled to +7C at a rate of 15 ml/min.Reperfusion arrhythmias and ST segment changes were assessed during the first day, viable myocardial volume (MRI) after 6 months.Results: Reperfusion arrhythmias were detected in 14.3% in the MG and 32.1% in the CG (p<0.05),Ventricle arrhythmia were 14.9% in the MG and 16.2% in the CG.ST elevation V1-V5 more than 1500 stenosis of the left main coronary artery, smoking, history of AMI, therapy with aspirin, β-blockers, and statins were an independent predictors of reperfusion arrhythmias.The size of the final zone of necrosis (MRI data) was 23±7% in the MG and 32±9% in the CG (p<0.05).Conclusions: Local hypothermia of the infarct-related artery allows to reduce the reperfusion arrhythmias (14.3% vs. 32.1%)and zone of myocardial necrosis (23±7% in the MG and 32±9% in the CG (p<0.05)
