Abstract

Objective: Cardiovascular diseases represent the mortality main cause in diabetic population. To evaluate prevalence and control of Diabetes Mellitus (DM) in patients admitted to the emergency room due to an acute vascular event. Design and method: We analyzed retrospectively 3635 patients (65,5% men) with a mean age of 71,15 (SD:12,6) that were admitted to the emergency room consecutively since January 2009 until December 2011 due to an acute vascular event; acute coronary syndrome (ACS), stroke or peripheral acute arterial disease (PAD). Patients were classified in two groups: those with known DM (n = 1265) and patients with not known diabetes mellitus, NDM (n = 2253). Results: DM group had elderly patients [72,9 (SD:9,8) vs. 70,1(SD:13,9)*]. DM group presented more ACS (47,7 vs. 43.5%*) and PAD (21 vs. 11,5%*) and an inferior ratio of Stroke (31,3 vs. 44,9*). HbA1C was performed in 881 patients (66,3%) in the DM group and 1024(44.4%) in NDM group. 18,1% (186 patients) with not known diabetes mellitus presented a HbA1C > 6,5%. DM patients receiving insulin treatment had worse controls than patients with oral treatment (8.0 vs. 7.6 % p > 0.05). In-hospital mortality was greater in DM patients than in NDM (11.0% vs. 9.6% *). (* p < 0.01). Conclusions: Prevalence of Diabetes Mellitus was high (34.8%). From the not known diabetic patients group a 18% had a recent diagnose of diabetes with an HbA1c > 6,5%. This test should be performed in all patients that are admitted due to an acute vascular event. Patients on oral antidiabetic agents presented better controlled than patients receiving insulin but differences were not statistically significant. In-hospital mortality was greater in diabetic population than in non-diabetic patients.
