<i>V</i> E/ <i>V</i> CO2 Slope is Associated with Abnormal Resting Haemodynamics and is a Predictor of Long-Term Survival in Chronic Heart Failure

Abstract

The V(E)/V(CO(2)) slope, as an index of ventilatory response to exercise, improves the risk stratification of CHF patients. Interstitial pulmonary oedema may be a pathophysiological mechanism of inefficient ventilation during exercise in these patients.
