Research of diabetes mellitus combined with myocardial infarction

Objective To analyze the characteristics of coronary lesions and clinical symptoms of patients with diabetes mellitus(DM) combined with acute myocardial infarction(AMI).Methods Clinical data of 217 cases of myocardial infarction patients were analyzed retrospectively,and all patients were divided into the diabetic mellitus group(DM group) and non-diabetic mellitus group(NDM group) according to whether combined with mellitus diabetes or not.The coronary lesion characteristics,clinical symptoms and infarction area of the two groups were comparative analyzed.Results Blood glucose(BG),total cholesterol(TC),triglyceride(TG) levels of DM group were all higher than those of the NDM group(P 0.05 or P 0.01);compared with the NDM group patients,incidence of double-vessels,three-vessels lesion,moderate and severe degree of coronary artery stenosis in the DM group were significantly higher(P 0.05 or P 0.01);hypertension,atypical chest pain,arrhythmia,heart failure,cardiogenic shock and pulmonary infection of patients in the DM group were significantly higher than the NDM group(P 0.05 or P 0.01);compared with the NDM group,incidence of myocardial multi-site infarction and non-Q wave in the DM group had significantly statistical differences(P 0.05 or P 0.01).Conclusion Coronary lesions and clinical symptoms of mellitus diabetic patients combined with myocardial infarction are more serious than non-diabetic patients with myocardial infarction.
