Background: The significance of admission blood glucose level in nondiabetic patients with heart failure (HF) is unknown. We examined the possible association between admission glucose levels and outcome in a large cohort of hospitalized patients with HF. Methods: We analyzed the data of 4102 patients with HF, who were hospitalized during a prospective national survey. The present study focuses on a subgroup of 1122 nondiabetic patients with acute HF who were admitted because of acute HF or exacerbation of chronic HF. Results: In-hospital mortality was twice as high in patients with admission blood glucose levels in the third tertile (7.2%) compared with the first (3%) and second (4%) tertiles (P=.02). Furthermore, mortality risk was correlated with admission glucose levels; each 18-mg/dL (1-mmol/L) increase in glucose level was associated with a 31% increased risk of in-hospital mortality (adjusted odds ratio, 1.31; 95% confidence interval, 1.10-1.57; P=.003) and a 12% increase in 60-day mortality (adjusted hazard ratio, 1.12; 95% confidence interval, 1.01-1.25; P=.04). Admission blood glucose levels remained an independent predictor of in-hospital and 60-day mortality even after the exclusion of 315 patients (28%) with acute myocardial infarction and HF. The 6- and 12-month mortality rates were similar in patients with and without abnormal admission blood glucose levels. Conclusions: Elevated admission blood glucose levels are associated with increased in-hospital and 60-day mortality, but not 6-month or 1-year mortality, in nondiabetic patients hospitalized because of HF.
