Shortness of breath is related to a loss of ventilatory efficiency [1, 2].

[3] in a scholarly fashion in the present issue of the European Respiratory Journal, cardiopulmonary exercise testing with measurements of ventilation and gas exchange have to be part of the initial evaluation and follow-up of any patient with a cardiac or a respiratory condition.
