Exercise capacity and heart rate recovery response to exercise in morbidly obese female patients with obstructive sleep apnoea syndrome.

Abstract

INTRODUCTION:To study exercise capacity and heart rate (HR) recovery after peak exercise in morbidly obese female patients with obstructive sleep apnoea (OSA). METHODS:Twenty-four morbidly obese female patients (36.17 ± 9.20 years and 45.20 ± 5.41 kg.m diagnosed with OSA underwent cardiopulmonary exercise testing (CPET) for assessment of peak oxygen uptake (V'O2) and heart rate (HR) recovery at 30, 60 a index [AHI] <15 h-1) and moderate-to-severe (AHI RESULTS: For the entire study population, peak V'O2 was 15.58 ± 2.44 ml.min were found between moderate-to-severe and mild OSA (16.11 ± 2.37 vs. 15.19 ± 2.50 ml.min respectively). HR recovery registered at any time after the peak workload also did not differ between both groups. Nonetheless, the percentage of HR decrease at 90 seconds in the patients with moderate-to-severe OSA (p=.073), and it was negatively correlated with the oxygen desaturation index (r =-0.679, p=.044).

To study exercise capacity and heart rate (HR) recovery after peak exercise in morbidly obese female patients with obstructive sleep apnoea (OSA).four morbidly obese female patients (36.17 ± 9.20 years and 45.20 ± 5.41 kg.m diagnosed with OSA underwent cardiopulmonary exercise testing (CPET) for assessment of peak oxygen uptake (V'O2) and heart rate (HR) recovery at 30, 60 and 90 seconds. Comparisons were made between mild (apnoea severe (AHI ≥15 h-1) OSA.For the entire study population, peak V'O2 was 15.58 ± 2.44 ml.min-1.kg-1. No differences in peak V'O2 severe and mild OSA (16.11 ± 2.37 vs. 15.19 ± 2.50 ml.min respectively). HR recovery registered at any time after the peak workload also did not differ between both groups. Nonetheless, the percentage of HR decrease at 90 seconds of recovery time was almost statistically significantly lower severe OSA (p=.073), and it was negatively correlated with the oxygen desaturation Exercise capacity is not different between patients with mild and moderate -to-severe OSA tend to have a slower HR recovery response to exercise than those with milder OSA. Finally, the oxygen desaturation index is related to this slower chronotropic response.Obstructive sleep apnoea, Exercise test, Female, Heart rate, Obesity.May 11, 2017; Published May 23, 2017...
