Do specific cardiopulmonary exercise test parameters (breathing reserve, OUES, AT, VO2/WR slope) discriminate between patients with heart failure and COPD?
Breathing reserve and oxygen uptake efficiency slope are superior to anaerobic threshold for discriminating between heart failure and COPD during cardiopulmonary exercise testing.
Breathing reserve and OUES discriminate heart failure from COPD. Despite it being considered an important determinant of cardiac dysfunction, the AT could not discriminate these typical clinical populations while the VO2/WR slope showed poor to moderate discriminant ability.
