  • legend BMI = body mass index; peak Vo2= peak oxygen consumption; Ve/Vco2= slope of the relation between ventilation and carbon dioxide production; LVEF = left ventricular ejection fraction by radionucleide ventriculography; NYHA = New York Heart Association classification of symptoms in chronic heart failure. None of the differences is significant; p > 0.2.
