Hemodynamic, Metabolic and Ventilatory Responses to Exercise in Adults with Congenital Heart Disease

Abstract Background: Congenital heart disease in adults shares some features with heart failure (HF), including exercise intolerance, ventilatory inefficiency, inflammatory and neurohormonal activation, cardiac arrhythmias and myocardial fibrosis. Over the last years, cardiopulmonary exercise test has gained importance in the diagnostic and prognostic evaluation of congenital heart diseases, as has already occurred in HF. Objective: To describe the behavior of hemodynamic, metabolic and ventilatory parameters in response to exercise in adults with congenital heart disease. Methods: Observat...
