ABSTRACT
OBJECTIVE: To assess the impact of type 2 diabetes mellitus (T2DM) on prognosis of patients hospitalized because of acute decompensated heart failure (ADHF). MATERIALS AND METHODS: We analyzed data of the hospital register of ADHF which comprised information on 735 patients (254 [35%] with T2DM) consecutively admitted in 2010-2011. Median follow-up was 1790 days. RESULTS: The presence of T2DM was associated with increased risk of death: during the index hospitalization due to ADHF (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.0-2.8), within 18 months (HR 1.4, 95% CI 1.0-1.8), and within 5 years (HR 1.3, 95% CI 1.0-1.5). CONCLUSIONS: T2DM is common among acute decompensated heart failure patients (up to 35% of cases). T2DM is an independent risk factor of death during the index hospitalization and over the next 18 months and 5 years.
