E-CPET Score: Explanation and Clinical Context The E-CPET Score integrates cardiopulmonary exercise testing (CPET) parameters with echocardiographic findings to assess the risk of adverse outcomes in patients with congenital heart disease (CHD). It combines peak oxygen consumption (VO₂peak), ventilatory efficiency (VE/VCO₂ slope), right ventricular ejection fraction (RVEF), and patient age to provide a comprehensive
Exercise Oscillatory Ventilation (EOV) Index: Explanation and Clinical Context Exercise Oscillatory Ventilation (EOV) is characterized by cyclic fluctuations in ventilation during exercise, observed on cardiopulmonary exercise testing (CPET). The EOV Index combines the severity of oscillations, exercise capacity (peak VO2), and ventilatory efficiency (VE/VCO2 slope) to quantify the prognostic burden in heart failure
