Why the study?
Is the V(E)/V(CO(2)) slope associated with abnormal resting haemodynamics and long-term survival in patients with chronic heart failure?
Is the V(E)/V(CO(2)) slope associated with abnormal resting haemodynamics and long-term survival in patients with chronic heart failure?
The V(E)/V(CO(2)) slope serves as a valuable index for risk stratification and predicting long-term survival in chronic heart failure patients.
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.
