Cardiopulmonary exercise testing (CPET) helps in detecting disorders of the
cardiovascular, pulmonary, and skeletal muscle systems. It has a class I
(indicated) recommendation from the American College of Cardiology and American
Heart Association for evaluating exertional dyspnea of uncertain cause and for
evaluating cardiac patients being considered for heart transplant. Advances in
hardware and software and ease of use have brought its application into the
clinical arena to the point that providers should become familiar with it and
consider it earlier in the evaluation of their patients.
