[Influence of diabetes mellitus on the management and prognosis of non-ST-elevation acute coronary syndrome].

The presence of diabetes mellitus worsens prognosis in acute coronary syndromes. The aim of our study was to analyze retrospectively the influence of diabetes mellitus on the management and prognosis of patients with non-ST-segment elevation acute coronary syndrome. We compared the baseline clinical characteristics of 273 patients (93 diabetic and 180 non-diabetic) admitted consecutively to our department with the diagnosis of non-ST-segment elevation acute coronary syndrome. In both groups, we assessed the medical treatment given during hospitalization and the use of coronary angiography, percutaneous coronary intervention, and coronary artery bypass grafting. Finally, we determined the incidence of heart failure during hospitalization and mortality at 28 days and 6 months in both groups. Multifactorial analysis revealed that diabetes was an independent risk factor for mortality during the study period. Data from our registry indicate that these findings were not associated with more extensive use of interventions in diabetic patients.
