Aim Skeletal muscle mass is associated with exercise tolerance in patients with chronic heart failure (CHF). Anthropometric indicators are used to evaluate skeletal muscle mass, as these can be easily assessed in clinical practice. However, the association between anthropometric indicators and exercise tolerance is unclear. This study aimed to investigate the association between anthropometric indicators and exercise tolerance in CHF patients. Methods We evaluated 69 patients with CHF. Mid‐arm circumference, mid‐arm muscle circumference (MAMC), calf circumference and body mass index were measured as the anthropometric indicators. Exercise tolerance was evaluated according to the peak oxygen uptake (VO 2 ). Correlation analyses were carried out to determine the association between peak VO 2 and anthropometric indicators. Furthermore, univariate and multiple regression analyses were carried out using peak VO 2 as the dependent variable, and age, male, left ventricular ejection fraction, angiotensin II receptor blocker or angiotensin converting enzyme inhibitor, diuretics, B‐type natriuretic peptide, estimated glomerular filtration rate, hemoglobin and anthropometric indicators as the independent variables. Results There were significant positive correlations between the peak VO 2 and mid‐arm circumference ( r s = 0.378, P = 0.001), MAMC ( r = 0.634, P < 0.001) and calf circumference ( r = 0.292, P = 0.015). In multiple regression analysis, MAMC (β = 0.721, P < 0.001) and estimated glomerular filtration rate (β = 0.279, P = 0.007) were independent factors associated with peak VO 2 . Conclusions MAMC is independently associated with peak VO 2 in CHF patients. Thus, MAMC could be an indicator of exercise tolerance, which is closely related to the severity and prognosis of CHF.
