Cardiopulmonary Exercise Testing in Adults with Congenital Heart Disease: Can We Prognosticate and Improve Prognosis?
The primary task of the cardiopulmonary system is to provide blood flow and oxygen in quantities sufficient to support the individual's metabolic needs. The cardiopulmonary system is maximally stressed when an individual's metabolic rate is increased, a condition that occurs most commonly during physical activity or exercise. Cardiopulmonary exercise testing (CPX) quantitatively assesses a patient's capacity to adapt to the hemodynamic demands of exercise. Those who are found to have a cardiopulmonary system incapable of supporting normal amounts of exercise are likely to be less resilient, more vulnerable to the illnesses and more predisposed to health complications when confronting inevitable challenges of life. A weakened cardiopulmonary system is also likely to be more susceptible to further damage or injury. It is therefore not surprising that data from CPX has been found to carry powerful and important prognostic implications. (SELECT FULL TEXT TO CONTINUE)
