[Impact of diabetes on mortality after myocardial infarction].
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).


CONCLUSIONS
Diabetic patients with myocardial infarction have poor prognosis and hyperglycemia was associated with in hospital mortality.
