Introduction. The relation between minute ventilation (VE) and carbon dioxide production (VCO2) can be characterised by the instantaneous ratio of ventilation to carbon dioxide production, the ventilatory equivalent for CO2(VEqCO2). We hypothesised that the time taken to achieve the lowest VEqCO2(time to VEqCO2 nadir) may be a prognostic marker in patients with chronic heart failure (CHF).Methods. Patients and healthy controls underwent a symptom-limited, cardiopulmonary exercise test (CPET) on a treadmill to volitional exhaustion.Results. 423 patients with CHF (mean age years; 80% males) and 78 healthy controls (62% males; age years) were recruited. Time to VEqCO2 nadir was shorter in patients than controls ( s versus  s; ). Univariable predictors of all-cause mortality included peak oxygen uptake (), VEqCO2nadir (), and time to VEqCO2nadir (). In an adjusted Cox multivariable proportional hazards model, peak oxygen uptake () and VEqCO2nadir () were the most significant independent predictors of all-cause mortality.Conclusion. The time to VEqCO2nadir was shorter in patients with CHF than in normal subjects and was a predictor of subsequent mortality.
