Cardiopulmonary Exercise Test (CPET)
The Cardiopulmonary Exercise Test is a highly sensitive, non-invasive stress test. It is considered a stress test because the exercise stresses your body’s systems by making them work faster and harder. A disease or condition that affects the heart, lungs or muscles will limit how much faster and harder these systems can work. A CPET assesses how well the heart, lungs, and muscles are working individually, and how these systems are working in unison. Your heart and lungs work together to deliver oxygen to your muscles, where it is used to make energy, and to remove carbon dioxide from your body.
The full cardiopulmonary system is assessed during a CPET by measuring the amount of oxygen your body is using, the amount of carbon dioxide it is producing, your breathing pattern, and electrocardiogram (EKG) while you are riding a stationary bicycle. The traditional treadmill stress test only relies on the EKG, which only partially assesses the heart and nothing else. Besides detecting problems in multiple body systems, the CPET is also used to monitor changes in your disease condition, the effect of certain medications on your body, and if medical therapy is improving your condition.
