Myocardial infarction is a common cause of mortality in people with diabetes. The aim of this study was to determine early and mid-term mortality in diabetic patients with myocardial infarction and to determine if hyperglycemia was predictor of mortality. We conducted a retrospective study of 100 diabetic patients compared with 100 non diabetic patients who were hospitalised in our institution between 1999 and 2003 for myocardial infarction.
Results: Hospital and one year mortality were highest among diabetic patients compared with non diabetic patients. Multivariate analysis showed that admission plasma glucose was a consistent predictor factor of in hospital mortality RR 1.2 (IC 1.02-1.47). Admission plasma glucose was significantly higher in nonsurvivors diabetic patients than in survivors (22.7 vs 16 mmol/l P = 0.04). The predictor factors of one year mortality was age, female sex and no beta blocker at discharge RR5.3 (1.9-14.3).
Conclusion: Diabetic patients with myocardial infarction have poor prognosis and hyperglycemia was associated with in hospital mortality.
