Predicting Mortality Risks Using Body Mass Index and Weight Loss at Admission in Patients with Heart Failure.

ABSTRACT:

Background

The association of the combination of body mass index (BMI) and weight change at admission with prognoses in patients with heart failure (HF) is unclear. Therefore, we investigated whether BMI and weight changes at admission affect mortality in patients with HF.

Methods

This retrospective cohort study lasted 99 months, starting in April 2014, and included 4,862 patients with HF from a Japanese real-world database. Cubic and thin-plate smoothing spline analyses were performed to investigate the association of BMI and weight changes with mortality. The percentage weight change was calculated every 6 months. The study outcome was the presence or absence of death.

Results

The patients' mean age was 81.5±9.6 years, and 1,239 (25.5%) patients died. Cubic spline a
