The geriatric nutritional risk index (GNRI) is a simple and objective nutritional assessment tool for elderly patients. Lower GNRI values are associated with a worse prognosis in patients with heart failure (HF). However, few data are available regarding the prognostic effect of the GNRI value for risk stratification in patients at risk for HF.Methods and Results:We retrospectively investigated 1,823 consecutive patients at risk for HF (Stage A/B) enrolled in the IMPACT-ABI Study. GNRI on admission was calculated as follows: 14.89×serum albumin (g/dL)+41.7×body mass index/22. Patients were divided into 2 groups according to the median GNRI value (107.1). The study endpoint was a composite of cardiovascular (CV) events, including CV death and hospitalization for worsening HF. Over a 4.7-year median follow-up, CV events occurred in 130 patients. In the Kaplan-Meier analysis, patients with low GNRI (&lt;107.1, n=904) showed worse prognoses than those with high GNRI (≥107.1, n=919) (20.2% vs. 12.4%, P&lt;0.001). In the multivariable Cox proportional hazards analysis, low GNRI was significantly associated with the incidence of CV events (hazard ratio: 1.48, 95% confidence interval: 1.02-2.14; P=0.040).
