Robustness of the oxygen uptake efficiency slope to exercise intensity in patients with coronary artery disease.


Oxygen uptake efficiency slope (OUES) and ventilatory efficiency (VE/VCO2 slope) are widely used as submaximal measurements of cardiopulmonary exercise testing as the evaluator or prognosticator of cardiac diseases. However, very few studies have compared the effects of submaximal exercise on these measurements. A total of 58 patients with coronary artery… (More)
