Table 3 American College of Cardiology/American Heart Association guidelines for cardiopulmonary exercise testing
ClassIndication
I (indicated)1 Evaluation of exercise capacity and response to treatment in patients with heart failure who are being considered for heart transplantation
2 Assistance in the differentiation of cardiac versus pulmonary limitations as a cause of exercise-induced dyspnoea or impaired exercise capacity when the cause is uncertain
IIa (good supportive evidence)Evaluation of exercise capacity when indicated for medical reasons in patients for whom the estimates of exercise capacity from exercise test time or work rate are unreliable
IIb (weak supportive evidence)1 Evaluation of the patients response to specific therapeutic interventions in which improvement of exercise tolerance is an important goal or end point
2 Determination of the intensity for exercise training as part of comprehensive cardiac rehabilitation
III (not indicated)Routine use to evaluate exercise capacity
