Effect of diabetes mellitus on the mortality of patients with acute myocardial infarction during hospitalization

Objective To investigate the diabetes mellitus on the mortality of patients with acute myocardial infarction(AMI) during hospitalization. Methods Among 624 case with AMI,136 cases with diabetes mellitus were in group A,the others were in group B,and then compare the age,the clinic behavior and complication between the two groups.To identify risk factors that are predictive of in-hospital death,multivariate logistic regression analysis was used.Results Compared with those non-diabetes mellitus,the diabetes mellitus were substantially older[(66±9)]vs(64±9) years,P0.01],had a high level of fasting glucose[(10.8±3.9)vs(5.3±1.5)mmol/L,P0.01)].Patients with killip class greater than or equal to Ⅲ(12.5% vs 6.1%,P0.01) were more common in group A than in group B.The cases with hypertension,hyperlipidemia and cardiac arrhythmias in group A had obvious differences between the two groups(P0.05).An increased mortality was demonstrated in group A during the hospitalization phase of AMI(15.4% vs 5.9%,P0.01).Conclusion Diabetes mellitus is an independent predictor of in-hospital death in hospitalized patients with AMI.
