Patients with heart failure (HF) are sometimes classified as malnourished, but the prognostic value of nutritional status in acute HF (AHF) remains largely unstudied. 1214 patients who were admitted to the intensive care unit between January 2000 and June 2016 were screened based on their serum albumin, lymphocyte count, and total cholesterol measures. A total of 458 HF patients were enrolled in this study. The Prognostic Nutritional Index (PNI) is calculated as 10 × serum albumin (g/dL) + 0.005 × lymphocyte count (per mm3) (lower = worse). The Controlling Nutritional Status (CONUT) score is points based, and is calculated using serum albumin, total cholesterol, and lymphocyte count (range 0-12, higher = worse). Patients were divided into three groups according to PNI: high-PNI (PNI < 35, n = 331), middle-PNI (35 ≤ PNI < 38, n = 50), and low-PNI (PNI ≥ 38, n = 77). They were also divided into four groups according to CONUT score: normal-CONUT (0-1, n = 128), mild-CONUT (2-4, n = 179), moderate-CONUT (5-8, n = 127), and severe-CONUT (≥9, n = 24). The PNI, which exhibited a good balance between sensitivity and specificity for predicting in-hospital mortality [66.1 and 68.4
