Magnitude, treatment, and impact of diabetes mellitus in patients hospitalized with non-ST segment elevation myocardial infarction: A community-based study.

Purpose of the Study: To examine differences in the characteristics, treatment practices and in-hospital outcomes of patients with and without previously diagnosed diabetes hospitalized for non-ST segment elevation myocardial infarction.
Key Methods: The study cohort consisted of 3916 patients diagnosed with non-ST segment elevation myocardial infarction at all 11 central MA medical centres between 1999 and 2009, of whom 1475 (38%) had been previously diagnosed with diabetes.
Main Results: Diabetic patients were more likely to have received treatment with effective cardiac medications, and to have undergone coronary bypass surgery, but were less likely to have received a percutaneous coronary intervention, than non-diabetic patients. Patients with a history of diabetes were more likely to have developed cardiogenic shock, heart failure and died during their index hospitalization than non-diabetic patients.
Main Conclusion: Diabetic patients presenting with non-ST segment elevation myocardial infarction remain at high risk of developing significant clinical complications during hospitalization.
