First plasma glucose value after urgent admission and in-hospital mortality in acutely decompensated heart failure

Abstract Background We used data from three Methods and results We identified 788 HF admissions (62% female; median age 83.3 years). 20.9% had chronic kidney disease, 7.7% cancer history, 24.7% acute renal failure and 29.7% concomitant infection. Mean first PG was 124.3 ± 32.4 mg/dl; 22.7% had stress hyperglycemia. Fifty-six people died (IHM = 7.1%). Women, older patients and people with infections showed higher PG values. People who died had higher PG values (136.3 ± 43.9 vs. 123.4 ± 31.2 mg/dl;  p  = 0.029). In a multivariate regression model with IHM as main outcome, the first PG (per mg/dl, odds ratio (OR): 1.01 [1.00–1.02]; p  = 0.045), age (per year, OR: 1.06 [1.02–1.10]; p  = 0.003) and acute renal failure (OR: 0.42 [0.24–0.74]; p  = 0.003) remained significantly associated with IHM. Conclusions The first PG value predicted IHM in participants without diabetes after admission for heart failure.
