Association between glycemic status, renal function and emergency hospitalization for cardiovascular events in diabetes mellitus.

Emergency hospitalization for cardiovascular events is a major clinical problem in patients with diabetes mellitus, especially when poor glycemic control and renal dysfunction coexist. Therefore, it is of interest to evaluate 225 diabetic patients presenting to the emergency department with cardiovascular symptoms, assessing glycemic status and renal function. Poor glycemic control (mean HbA1c 9.1 ± 1.8; 37.8% with HbA1c > 9%) and renal impairment (42.6% with eGFR < 60 mL/min/1.73m2) were common. Acute coronary syndrome (34.2%) was the most frequent presentation, with 72.4% requiring hospitalization and 21.7% ICU admission. HbA1c > 9% (adjusted OR = 2.34) and eGFR < [(60 mL/min)/1.73m2] (adjusted OR = 2.89) were independent predictors of emergency cardiovascular hospitalization.
