Introduction: Hypoglycemia is one of the frequently encountered phenomena in hospitalized patients, mainly with diabetes mellitus; however, it is sometimes seen in patients without diabetes mellitus. Risk factors like advanced age, comorbid diseases, aggressive hyperglycemia therapy, etc. , can play a role in the contribution of hypoglycemia. Heart failure is a significant healthcare burden in the United States; mortality due to heart failure has been increasing, and the lifetime risk of heart failure has risen to 24%. There are limited studies investigating how hypoglycemia affects outcomes in heart failure. Methods: We conducted a retrospective analysis using a national inpatient sample from 2017 to 2020. For diseases/comorbidities, International Classification of Disease (ICD-10) codes were used. Data analysis was done using STATA. Multivariate regression analysis was used to calculate the adjusted odds ratio. The primary outcomes of the study were mortality, and secondary outcomes were length of stay (LOS), total cost of hospitalization, septic shock, pulmonary edema, acute respiratory failure (ARF), mechanical ventilation, acute respiratory distress syndrome (ARDS), and acute kidney injury (AKI). Results: There was a total of 21, 258, 175 patients with a diagnosis of heart failure. There were 158, 175 patients with a diagnosis of hypoglycemia. There were significant outcomes in patients with hypoglycemia on rates of mortality (adjusted mean difference=3. 64, 14. 55% vs. 4. 91%, p0. 001), LOS (adjusted mean difference =2. 03, 8. 50% vs. 6. 22%, p0. 001), the total cost of hospital stays (adjusted mean difference=21530, 103, 773 vs. 77057, p0. 001), septic shock (aOR=4. 05, 14. 22% vs. 3. 84%, p0. 001), ARF (aOR =1. 75, 24. 71% vs. 15. 88%, p0. 001), mechanical ventilation (aOR=2. 84, 14. 84% vs. 5. 21%, p0. 001), ARDS (aOR=2. 15, 0. 57% vs. 0. 24%, p0. 001), and AKI (aOR=1. 65, 41. 38% vs. 29. 89%, p0. 001) compared to patients without hypoglycemia. There were no significant outcomes in the rate of pulmonary edema (aOR=1. 09, 0. 54% vs. 0. 46%, p=0. 24). Conclusion: Hypoglycemia increases mortality, duration of hospital stays, health care cost, and health care burden. Hypoglycemia nevertheless results in worse hospital outcomes and higher expenses as compared to non-hypoglycemia due to higher mortality rates, LOS, cost, and hospital outcomes. Blood sugar levels should be monitored frequently to minimize hospitalization complications and improve outcomes. Presentation: 6/1/2024
