Summary
The pathophysiology of heart failure with preserved ejection fraction (HFpEF) is complex and multifactorial. Chronotropic incompetence has emerged as a crucial mechanism, particularly in elderly patients. Betablockers, drugs with negative chronotropic effect, are commonly used in HFpEF, despite current evidence does not support its routine use in these patients. The aim of this work is to evaluate the effect of betablockers withdrawal in patients with HFpEF and chronotropic incompetence on functional capacity assessed by the peak oxygen consumption at maximal exercise (peakVO2) at 15 and 30 days after the interventionPhase:
