title: The role of gas analysis in stress testing.
abstract: By providing measurements of O2 uptake and CO2 production during exercise, cardiopulmonary exercise testing can (1) distinguish between cardiac and pulmonary limitations in patients with dyspnea; (2) measure disability and provide an accurate exercise prescription; (3) provide physiologically relevant endpoints for assessing interventions; (4) define low-risk patients after uncomplicated myocardial infarction who may be safely assigned to medical therapy; and (5) stratify patient with left ventricular dysfunction by prognosis and functional capacity, identifying those who may benefit most from cardiac transplantation.
