Application risk assessment and prognosis
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 <0.0001
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.
