Muscle ergoreflex involved during exercise did not contribute to ventilatory response in heart failure with optimized treatment

OBJECTIVE The muscle ergoreflex has been postulated as a link between muscle metabolic changes and the abnormal responses in hemodynamic, ventilation and autonomic tone in heart failure (HF). Beta-blocker (BB) improves hemodynamic and decrease ventilatory response, but had no effect on exercise capa...

Summary:OBJECTIVE The muscle ergoreflex has been postulated as a link between muscle metabolic changes and the abnormal responses in hemodynamic, ventilation and autonomic tone in heart failure (HF). Beta-blocker (BB) improves hemodynamic and decrease ventilatory response, but had no effect on exercise capacity. However, no data are available about ergoreflex on exercise in HF under optimized BB therapy. We investigated the ergoreflex in the leg during treadmill 6-minute cardiopulmonary walking test (6W) in CHF with optimized treatment receiving BB compared with control group.
