Geriatric Nutritional Risk Index Predicts All-Cause Mortality in Patients with Heart Failure: A Systematic Review and Meta-Analysis

This meta-analysis evaluates the Geriatric Nutritional Risk Index (GNRI) as a predictor of all-cause mortality in heart failure (HF) patients.

Key findings:

Low GNRI (GNRI < 92) is associated with a 1.59 times higher risk of all-cause mortality in elderly HF patients.
Moderate GNRI risk (GNRI < 98) also predicts higher mortality rates compared to those with high GNRI scores.
Subgroup analysis indicates that GNRI’s predictive value varies based on heart failure subtype.
GNRI is an effective, simple tool for assessing malnutrition risk in heart failure patients.
The study highlights the importance of nutritional assessment in managing HF patients, suggesting that GNRI should be integrated into routine clinical evaluations.
