Alteration of glucose levels during PCI in patients with acute myocardial infarction and its influence on prognosis

Objective To investigate the alteration of glucose levels during percutaneous coronary intervention(PCT) and its influence on prognosis in patients with acute myocardial infarction. Methods A total of 85 non-diabetic patients with ST elevation MI receiving PCI were divided into 2 groups according to serum glucose(SG) levels on admission:group A,SG7.8 mmol/L(n = 48),group B,SG≥7.8 mmol/L(n = 37).Stress hyperglycaemia was defined as random SG level greater than or equal to 7.8 mmol/L on admission.The clinical data and heart failure,reinfarction, post-infarction angina,serious arrhythmias,and cardiac death within 30 days in the 2 groups were compared.Results The incidences of heart failure,reinfarction,post-infarction angina,serious arrhythmias,and cardiac death in group B were significantly higher than those in group A (P0.05).LVEF in group B(48.57±8.21)%was much lower than that in group A[(53.25±7.34)%,P0.05].Conclusion Abnormal increase in blood glucose on admission is associated with poor prognosis of AMI patients within 30 days after PCI.
