| Objective | We sought to establish the distribution, relation to cyanosis, and prognostic value of the V˙ E/V˙ CO2 slope across a wide spectrum of ACHD patients. |
| p Value | <0.05 |
| HR | 0.9 |
| Conclusion | Ventilatory response to exercise is abnormal across the spectrum of ACHD. Cyanosis is a powerful stimulus for such exaggerated ventilatory patterns irrespective of the presence of pulmonary arterial hypertension. Increased V˙ E/V˙ CO2 slope is the strongest exercise predictor of death in noncyanotic ACHD patients. |
