Obstructive sleep apnea reduces functional capacity and impairs cardiac autonomic modulation during submaximal exercise in patients with chronic obstructive pulmonary disease: A follow-up study

Chronic obstructive pulmonary disease (COPD) is a chronic, progressive disease1 that, when associated with other diseases, makes the individual's health status more critical. Therefore, COPD patients may be more subject to readmissions and exacerbations, with a higher incidence and prevalence of comorbidities, leading to a negative impact on these patients' clinical outcomes and prognosis.2 –4 In this context, some studies have observed the concomitant presence of COPD and obstructive sleep apnea syndrome (OSA), due to their similar findings, such as smoking, increased airway resistance, and systemic inflammation.
