Abstract Objective To evaluate clinical features and in- hospital outcomes of patients with acute ST- segment elevation myocardial infarction (STEMI) and diabetes.Methods Clinical data of 952 inpatients with acute STEMI were retrospectively analyzed.They were divided into diabetic group and non- diabetic group based on whether or not there is diabetes.The clinical features and in- hospital outcomes were compared between the two groups.Results Of 952 STEMI patients,187 cases had diabetes.Diabetic group had more female,non- smoker,and patients with chronic renal insufficiency and pulmonary infection.Serum creatinine and brain natriuretic peptide level,the ratio of three- vessel disease as well as serious lesion of right and left circumflex coronary artery were significantly higher in diabetic group than non- diabetic group.Heart failure,cardiogenic shock and all- cause mortality in hospital were significantly higher in diabetic (43.3%,9.6%,11.8%) than non- diabetic (29%,3.1%,6.1%) (all P<0.05) group.Multivariate logistic regression analysis showed that diabetes was an independent predictor for all- cause hospital mortality (OR=2.303,95%Cl: 1.304~4.068),cardiogenic shock (OR=2.784,95%Cl:1.409~5.502) and heart failure (OR=2.616,95%Cl: 1.564~4.375).Conclusion Diabetic patients have more complications and higher mortality in hospital after STEMI.
