Merrill JD, et al. - Researchers retrospectively identified hospitalized patients with heart failure (HF) undergoing bedside glucose monitoring with subcutaneous insulin orders over 2 years to assess hypoglycemia in this population. They defined hypoglycemia as any glucose value <3.9 mmol/L (70 mg/dL) within 24 hours of admission (Hypo1day) or throughout the hospitalization (HypoT), or any glucose value <2.2 mmol/L (40 mg/dL) throughout the hospitalization (HypoSevere). Hospitalized patients with HF vs those without HF demonstrated occurrence of hypoglycemia at a similar or lower frequency. Regardless of HF status, hypoglycemia seemed to be associated with increased hospital mortality.
