Abstract

© 2014 Sociedad Colombiana de Cardiología y Cirugía Cardiovascular.Background: Although body mass index (BMI) is associated with improved outcomes in establis-hed heart failure (HF), the impact of cardiorespiratory fitness on the obesity paradox is lessclear.Objective: The aim of this study was to evaluate the relationship between body mass index andcardiorespiratory fitness in terms of VO2max in patients with HF.Material and methods:A cross-sectional descriptive study was conducted on 40 patients with HF (age 66.8 ± 11.4 years, BMI 27.4 ± 4.8 kg·m-1, LVEF 40.5 ± 8.3%). BMI was measuredas an indicator of obesity and the risk was classified according to international benchmarks.Cardiorespiratory fitness, measured using the 6-min walk test (6’WT), oxygen consumption byVO(2)max, the distance and the number of steps, were grouped and compared with the bodymass index reference values.Results: In subjects with BMI ≥ 25 kg·m-1, negative correlations were observed in the distanceby 6’WT (rho = -0.50), number of steps (rho = -0.45), VO(2)max (rho = -0.49), and LVEF (rho= -0.32).Conclusion: This study suggests that higher body mass index values, "obesity paradox", arenot associated with a higher cardiorespiratory level using VO(2)max.
