Interval exercise training improves cardiac output at peak levels of exercise in COPD.
Interval exercise training reduces the magnitude of dynamic hyperinflation in COPD.
Mitigation of dynamic hyperinflation improves central hemodynamic responses to a given power output in hyperinflated COPD.
Rehabilitative exercise training induces a more efficient hemodynamic response to a given power output in patients with COPD.
Non-invasive measurement of cardiac output in patients with COPD may improve the evaluation of the efficacy of pharmacological and non-pharmacological interventions.
