Geriatric nutritional risk index predicts all-cause mortality in patients with heart failure: A systematic review and meta-analysis.

Abstract

Objectives Geriatric nutritional risk index (GNRI) might predict the all-cause mortality in patients with heart failure (HF). We performed a meta-analysis to evaluate the correlation between GNRI and all-cause mortality in patients with HF.

Methods We searched the PubMed, Medline, Cochrane Library, and Embase databases for clinical trials investigating the association between GNRI and all-cause mortality in patients with HF, having the primary endpoint as all-cause mortality.

Results In total, nine studies involving 7,659 subjects were included in the systematic review and meta-analysis. The results indicated that major risk and moderate risk GNRI (GNRI

Conclusions GNRI is a simple and well-established nutritional assessment tool to predict all-cause mortality in patients with HF.
