ObjectivesAdductor pollicis muscle thickness (APMT) has been used as a simple index for muscle mass for the assessment of nutritional status among hospitalized patients to identify malnutrition. The aim of this study was to evaluate the association between APMT and nutritional status in clinical patients diagnosed with congestive heart failure (CHF).MethodsAPMT was measured in 500 patients with CHF on the dominant side. Nutritional status was assessed means of by the Subjective Global Assessment (SGA). Functional classification was performed according to guidelines provided by the New York Heart Association (NYHA), which establishes four categories of CHF severity. Poisson regression was used to verify the association of APMT, malnutrition, and severity of CHF. P ≤ 0.05 was considered statistically significant.ResultsThe malnutrition prevalence varied from 1.5% in patients with functional class I CHF to 96.2% in patients classified as functional class IV (P ≤ 0.001). In both sexes, APMT values were significantly lower in patients who were malnourished (P< 0.001). The proportion of patients with CHF and malnutrition was higher among women than men (47.2 versus 37.4%, P = 0.027). Malnutrition was slightly more common among patients ≥60 y of age compared with other age groups (48.3%, P ≤ 0.001). APMT is a significant protective factor for malnutrition even after controlling for sex, age, body mass index, and CHF functional class.ConclusionsMalnutrition is highly prevalent among patients with CHF and is associated with functional class. APMT may be used as a simple index for muscle mass for the assessment of nutritional status in these patient populations, and is also associated with malnutrition in these patients, even after controlling for other risk factors.Copyright © 2019.
