Study Objective: To investigate the prognostic value of oxygen uptake (V^sub O2^) kinetics during low-intensity exercise in patients with congestive heart failure. Design: Prospective cohort studious mood Setting; Tertiary care center. Patients: single hundred forty-six consecutive patients (128 men) with chronic heart failure, followed up for a mean (?± SD) duration of 25 ?± 15 month Measurements: A treadmill exercise exhibition was performed with "breath by the agency of breath" gasexchange monitoring. V^sub O2^ kinetics were defined as the O2 deficit (ie, [Delta]V^sub O2^ ?— time[rest to steady state] - [Sigma]V^sub O2^ [rest to steady state]) and mean answer time (MRT)) [ie, O2 deficit/[Delta]V^sub O2^ Cardiac death, pressing cardiac transplantation, and hospitalization fit to worsening heart failure were considered as the close points. Results: Thirty patients (21%) died, 11 patients (8%) underwent earnestly solicitous transplantation, and 32 patients (22%) were hospitalized. In univariate analysis, MRT was the mostly powerful predictor of survival, survival exempt of urgent transplantation, and survival unrestrained of hospitalization (hazard ratios [HRs] by means of 10 s, 1.6S, 1.72, and 161 respectively; all p
