Brief Summary

Rationale. Chronic obstructive pulmonary disease (COPD) and heart failure (HF) coexist in approximately one third of patients presenting with one of these conditions. From a clinical standpoint, impaired tissue oxygen (O2) delivery stands as a common pathological mechanism of these cardiorespiratory diseases. Recent evidence suggest that muscle and cerebral blood flow and oxygenation are further impaired during exercise in patients with COPD-HF overlap compared to isolated diseases. However, it remains unknown whether impaired O2 delivery is associated with exaggerated manifestations of peripheral and central fatigue in COPD-HF overlap. In addition, improving cardiopulmonary interactions through non invasive positive pressure ventilation or through the addition of a hyperoxic gas mixture during exercise have been associated with enhanced cerebral and muscle O2 delivery and oxygenation in patients with COPD or HF. It is, therefore, conceivable that improved O2 delivery to these structures have beneficial influence on exercise capacity in patients with COPD-HF overlap due to less peripheral and central fatigue. Aims. To investigate the influence of impaired O2 delivery during exercise, and its alleviation with different interventions (non invasive positive pressure ventilation or hyperoxia), on neuromuscular fatigue in patients with COPD-HF.

Outcome Measures

Primary Outcomes (1)

  • Muscle fatigue

    Muscle fatigue assessed by magnetic stimulation of the femoral nerve

    Muscle fatigue assessed immediately after exercise, between-group (COPD vs COPD-HF under medical air) and within-group (medical air vs intervention trial in COPD-HF) comparisons

Secondary Outcomes (4)

  • Exertional symptoms

    Symptoms during exercise, between-group (COPD vs COPD-HF under medical air) and within-group (medical air vs intervention trial in COPD-HF) comparisons

  • Tissue oxygenation

    Tissue oxygenation during exercise, between-group (COPD vs COPD-HF under medical air) and within-group (medical air vs intervention trial in COPD-HF) comparisons

  • Cerebral blood flow

    Cerebral blood flow during exercise, between-group (COPD vs COPD-HF under medical air) and within-group (medical air vs intervention trial in COPD-HF) comparisons

  • Cardiac output

    Cardiac output during exercise, between-group (COPD vs COPD-HF under medical air) and within-group (medical air vs intervention trial in COPD-HF) comparisons

Study Arms (2)

Patients with COPD

ACTIVE COMPARATOR

Patients with COPD will only exercise under medical air (for between-group comparison: COPD vs COPD-HF)

Other: Medical air

Patients with COPD-HF overlap

EXPERIMENTAL

Patients with COPD-HF overlap will first exercise under medical air (for between-group comparison: COPD vs COPD-HF); Patients with COPD-HF overlap will then exercise under intervention (hyperoxia, for within-group comparison: medical air vs intervention trial)

Other: Medical airOther: Hyperoxia

Interventions

Exercise under medical air, both arms exposed.

Patients with COPDPatients with COPD-HF overlap

Exercise under hyperoxia, only experimental arm exposed.

Patients with COPD-HF overlap
