ABSTRACT
Objectives:
Malnutrition is associated with an increased risk of hospital readmission for heart failure in patients with acute decompensated heart failure (ADHF). Therefore, evaluation of the nutritional status in patients with ADHF may be important. The geriatric nutritional risk index (GNRI), the controlling nutritional status (CONUT) score, and the prognostic nutritional index (PNI) are widely used objective indexes for evaluation of the nutritional status. The present study was performed to determine the best nutritional index for predicting the prognosis in older adults with ADHF.Methods:
We retrospectively studied 167 older adults (>65 years of age) who were admitted with ADHF from January 2012 to December 2015 and discharged alive. The objective nutritional status was evaluated using the GNRI, CONUT score, and PNI at admission. The endpoint of this study was unplanned hospitalization for worsening heart failure (WHF) within 1 year after discharge.Results:
During the follow-up period, 58 patients were readmitted for WHF. In the multivariate Cox analysis, only the GNRI (p<0.0001) was independently associated with readmission for WHF among the three nutritional indexes. Kaplan-Meier analysis revealed that patients in the low-GNRI group (<90 as determined by receiver operating characteristic curve analysis) had a significantly greater risk of 1-year hospital readmission for WHF (p<0.0001; hazard ratio, 6.1; 95% confidence interval, 3.5-10.5).Conclusion:
Among the objective nutritional indexes, the GNRI is the best predictor of readmission for WHF within 1 year after discharge in older adults with ADHF.
