BackgroundNutritional status is related to clinical outcomes in patients with chronic heart failure (CHF). The prognostic nutritional index (PNI) is a simple tool to assess nutrition.AimTo evaluate the association between the PNI score and clinical outcomes in patients (60 years and older) hospitalized due to an acute exacerbation of CHF.MethodThis was a retrospective observational study. Patients hospitalized for acute CHF exacerbation between July 2015 and May 2020 were analyzed. Patients were followed until January 31, 2021. The primary end point was cardiovascular-related readmissions and all-cause mortality after hospital discharge. Secondary outcomes were factors associated with all-cause mortality. Patients were divided into normal nutrition (PNI > 38), moderate malnutrition (PNI = 35–38), and severe malnutrition (PNI < 35) groups.ResultsThe study included 355 patients (mean age 78 ± 9 years). The median follow-up was 769 days. Compared to survivors (n = 214), patients who expired (n = 133) were (1) older; (2) had lower PNI scores, lymphocyte counts, hemoglobin, albumin, total cholesterol, and serum sodium level; but (3) had higher serum creatinine levels, log(N-terminal-pro-B-type natriuretic peptide), and cardiac troponin I (P< 0.05). Multivariate analyses revealed that PNI was independently associated with all-cause mortality. The hazard ratio (HR) for moderate malnutrition versus normal nutrition was 1.624 (95% confidence interval [CI] 1.011–2.609,P= 0.045), while HR for severe malnutrition versus normal nutrition was 1.892 (95%CI 1.119–3.198,P= 0.017). Malnourished patients had significantly higher rates of cardiovascular readmissions and all-cause mortality.ConclusionLower PNI (malnutrition) was associated with worse clinical outcomes and was independently associated with all-cause mortality in patients with CHF.
