    ObjectivesThe aim of this study was to determine whether handgrip strength (HGS) has diagnostic accuracy for malnutrition assessment and whether it is an independent predictor of 90-d mortality in patients with acute decompensated heart failure (ADHF).MethodsThis cohort study evaluated patients with ADHF within 36 h of hospital admission. Subjective global assessment and handgrip dynamometry were performed and the patients' medical records were analyzed. Mortality was monitored by phone contact and/or medical record search after 90 d. Diagnostic accuracy was tested with receiver operating characteristic (ROC) curves, and survival was tested in a Cox model.ResultsThe sample consisted of 161 patients with ADHF who were predominantly male (62%) and older (77%), with a mean age of 68 y (60-75 y) and an ejection fraction of 37.7% ± 16.2%. According to subjective global assessment, 60% were suspected of malnourishment or were moderately or severely malnourished and these patients had lower HGS values than the well-nourished patients (P < 0.001). The ROC curve for HGS was sufficiently accurate to assess malnutrition (area under the curve [AUC] = 0.696; 95% confidence interval [CI], 0.614-0.779; P < 0.001) and had very good accuracy to predict severe malnutrition (AUC = 0.817; 95% CI, 0.711-0.923, P < 0.001). When analyzed by sex, HGS could only accurately detect malnutrition in men, although it could detect severe malnutrition in both men and women. During the 90-d follow-up period, there were 16 deaths (9.9%). An HGS cutoff value of 25.5 kg for men was considered significant for 90-d mortality (hazard ratio, 8.6; 95% CI, 1.1-70.9; P = 0.045).ConclusionThe results suggested that HGS is an independent indicator of malnutrition in patients with ADHF and can serve as a prognostic marker of 3-mo mortality in men.Copyright © 2021 Elsevier Inc.
