Objective: To describe differences in in-hospital morbidity and mortality, presenting characteristics and management practices of diabetic and non-diabetic patients with non-ST elevation myocardial infarction using data from Thai ACS registry.

Material and Method: Thai ACS registry is a multi-center, prospective project of nationwide registration in Thailand.

Results: The present study consisted of 3,548 patients with non-ST elevation myocardial infarction from 17 hospitals in about a 3-year period. About 50% of the patients with diabetes were more often female, with a greater prevalence of hypertension and dyslipidemia. The diabetic group was at an increased risk for congestive heart failure (adjusted odds ratio 1.84) but not increased risk for cardiac arrhythmia, cardiac mortality, and in-hospital mortality.

Conclusion: There was a very high prevalence of diabetes in non-ST elevation myocardial infarction from Thai ACS registry. These patients were at increased risk for congestive heart failure as index of hospitalization but were not at increased risk for in-hospital mortality when compared with patients without diabetes.
