Individual cardiac contractile response to exercise in pediatric cancer survivors with normal or impaired cardiopulmonary fitness. Survivors with impaired fitness had a blunted increase in left ventricular ejection fraction (LVEF) from rest to peak exercise (Fig. 2a). In contrast, resting right ventricular ejection fraction (RVEF) was lower in survivors with normal fitness, but showed a greater augmentation from rest to peak exercise (Fig. 2b)
