CPET is a vital tool providing critical metabolic and hemodynamic information for assessing exercise capacity and guiding management in patients with congenital heart disease.
Supports CPET in congenital heart disease assessment; extends prior reviews but leaves randomized outcome trials open.
Cardiopulmonary exercise stress testing (CPET) is a vital tool used to assess patients with a history of congenital heart disease. There are several tests in the cardiologist's armamentarium that allow for assessment of cardiac anatomy and function. The majority of these tests are only performed with the body at rest and some even require sedation. Exercise stress testing is unique in allowing assessment of the hemodynamic status of a patient in motion. In addition to providing all the information obtained during an exercise stress test, such as heart rate, rhythm, ST-segment analysis, and blood pressure, the CPET provides critical metabolic information. Parameters such as VO2, oxygen pulse, and VE/VCO2 slope help to detail the patient's physiology in a dynamic state. Decisions can then be better made regarding follow-up plans, acceptable exercise recommendations, and future interventions, if necessary. It allows insight into the patient's exercise capacity and quality of life. Norms for both children and adults with many forms of congenital heart disease are now available allowing appropriate comparisons to be made. This review will discuss in detail the CPET and its application in congenital heart disease.
