Key result

Older age, lower BMI, higher NYHA class, elevated CRP, COPD, reduced eGFR, and higher NT-proBNP were independently associated with malnutrition, which affected 17.7% of patients (model AUC 0.902).

Overview

May aid malnutrition screening in elderly HF via routine factors; leaves open whether interventions improve outcomes.

Key Points

  • To identify the clinical factors associated with malnutrition in elderly patients suffering from chronic heart failure.
  • Retrospective observational design at a tertiary hospital.
  • Inclusion of elderly patients (≥65 years) with chronic heart failure from January 2022 to December 2024.
  • Univariate and multivariate logistic regression analyses utilized to explore associations with malnutrition.
  • Among 203 patients, 36 (17.7%) were classified as malnourished.
  • Key factors linked to malnutrition included older age, lower body mass index, higher C-reactive protein, and reduced glomerular filtration rate.
  • The final model achieved an area under the curve of 0.902, indicating strong performance in predicting malnutrition.

Malnutrition diagnosed according to the Global Leadership Initiative on Malnutrition criteria

A combination of clinical, laboratory, and demographic factors can accurately identify malnutrition risk in elderly patients with chronic heart failure.

Cite This Study

Long et al. (2026) conducted an observational in chronic heart failure (n=203). Clinical risk factors was evaluated on Malnutrition. Older age, lower BMI, higher NYHA class, elevated CRP, COPD, reduced eGFR, and higher NT-proBNP were independently associated with malnutrition, which affected 17.7% of patients (model AUC 0.902).
