Different Determinants of Ventilatory Inefficiency at Different Stages of Reduced Ejection Fraction Chronic Heart Failure Natural History

It is not known whether determinants of ventilation (VE)/volume of exhaled carbon dioxide (VCO ) slope during incremental exercise may differ at different stages of reduced ejection fraction chronic heart failure natural history. VE/VCO slope was fitted up to lowest VE/VCO ratio, that is, a proxy of...

Description
Summary:It is not known whether determinants of ventilation (VE)/volume of exhaled carbon dioxide (VCO ) slope during incremental exercise may differ at different stages of reduced ejection fraction chronic heart failure natural history. VE/VCO slope was fitted up to lowest VE/VCO ratio, that is, a proxy of the VE/perfusion ratio devoid of nonmetabolic stimuli to ventilatory drive. VE/VCO slope tertiles were generated from our database (
