Introduction: Eating disorders (ED) such as bulimia and anorexia nervosa have detrimental implications on the health and wellbeing of children and young adults across the country. Cardiovascular implications are known to accompany these conditions, however there is a paucity of data looking specifically on the effects of NSTEMI on patients with these disorders. We sought to analyze this relationship further by examining these disorders within the national inpatient sample database to describe in-hospital trends and outcomes among those patients.
Methods: Data were extracted from the National Inpatient Sample (NIS) Database for the years 2019 and 2020. The NIS was searched for hospitalizations of adult patients with eating disorder(s) with and without a concomitant diagnosis of NSTEMI using international classification of diseases-10th revision codes. Multivariate logistic was used to adjust for confounders. The primary outcome was inpatient mortality. Secondary outcomes were hospital length of stay (LOS), and total hospital charges (TOTHCG). SPSS software was used for statistical analysis.
Results: This study included 16,889 patients who were diagnosed with eating disorders, of which only 56 (0.3%) patients were diagnosed with NSTEMI. ED patients with NSTEMI had higher prevalence of hypertension, diabetes mellitus and chronic kidney disease but not statistically different compared to patients with ED only. Multivariate regression showed that patients with both ED and NSTEMI had higher inpatient mortality compared to those with ED alone (OR 1.013, CI 1.011-1.015, p
Conclusion: In this nationally representative population‐based retrospective cohort study, we concluded that ED patients hospitalized with NSTEMI have increased in-hospital mortality and worse outcomes. More research is needed in this area
