The Relationship Between Body Mass Index and In-hospital Survival in Patients Admitted With Acute Heart Failure.

ABSTRACT:

Background

The association between Body Mass Index (BMI) and clinical outcomes following acute heart failure (AHF) hospitalization is debated in the literature. Our objective was to study the real-world relationship between BMI and in-hospital mortality in patients who were admitted with AHF.

Methods

In this retrospective, multi-center study, we utilized the National Inpatient Sample (NIS) database to identify a sampled cohort of patients who were hospitalized with AHF between October 2015 and December 2016. Outcomes of interest included in-hospital mortality and length of stay (LOS). Patients were divided into 6 BMI (kg/m²) subgroups according to the World Health Organization (WHO) classification: (1) underweight ≤ 19, (2) normal weight 20-25, (3) overweight 26-3
