Abstract:
Oxygen uptake kinetics during low-intensity exercise were investigated in 48 patients with congestive heart failure to assess their prognostic value compared with established predictors of prognosis including neurohumoral stimulation. Mean response time of oxygen uptake during low-intensity exercise, which does not require the patient's maximal effort, appears to be an important predictor of prognosis in these patients.
