No. 26 Relationship Between Cardiopulmonary Responses to Exercise Onset and Anaerobic Threshold in People With Heart Failure

Abstract

index (BMI) was measured as an indicator of obesity and the risk was classified according to international benchmarks. We compared the cardiorespiratory fitness by 6-min walk test (6'WT), oxygen consumption by VO( 2 )max, distance and the number of steps such as indicators of fitness. Results: We performed a cross-sectional descriptive study in 40 patients with HF (age 66.8 AE 11.4 years, BMI 27.4 AE 4.8 kg$m -1 , LVEF 40.5 AE 8.3%). In subjects with BMI â&U 26 kg$m -1 negative correlations were observed in the distance by 6'WT (rho Spearman ¼ -0.50), number of steps (rho Spearman ¼ -0.45), VO( 2 )max (rho ¼ -0.49) and LVEF (rho ¼ -0.32). Conclusion: This study suggests that "obesity paradox" is not related to a higher standard cardiopulmonary by VO( 2 )max.
