INDICATIONS

A cardiopulmonary stress test is usually indicated for the following:

  • Evaluation of unexplained shortness of breath.

  • Evaluation of exercise tolerance for a person with heart failure or coronary artery disease (CAD).

  • Evaluation of lung function. This is useful in patients with chronic obstructive pulmonary disease (COPD) or pulmonary hypertension.
