β-blockers Withdrawal in Patients With HFpEF and Chronotropic Incompetence: Effect on Functional Capacity (Preserve-HR) (Preserve-HR)

Betablockers Withdrawal in Patients With Heart Failure With Preserved Ejection Fraction and Chronotropic Incompetence: Effect on Functional Capacity Rationale and Study Design of a Prospective, Randomized, Controlled Trial

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 intervention

Study Overview

Detailed Description

This is a prospective, crossover, randomized (1:1) and single center study. After randomization, clinical and cardiac rhythm will be continuously registered during 30 days. The primary endpoint (peakVO2) will be assessed by cardiopulmonary exercise testing (CPET) at 15 and 30-day in both groups. Patients with HFpEF, functional class NYHA II-III, chronic treatment with betablockers, and chronotropic incompetence will be enrolled. A sample size estimation [alfa: 0.05, power: 90%, a 15% loss rate, and delta change of mean peakVO2: +1.2 mL/kg/min (SD±2.5)] of 52 patients would be necessary to test our hypothesis.

In conclusion, optimizing therapy that improve quality of life and autonomy has become a health care priority in HFpEF. The investigators believe this study will add important knowledge for the treatment of a subgroup of HFpEF.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Arm A

Controlled Withdrawal of Beta-blockers and Cardiopulmonary Exercise Testing (CPET) Patient will be assessed for chronotr0pic incompetence by CPET. If the patient exhibits chronotropic incompetence, we will reduce half dose of previous beta-blocker.

A cardiologist will evaluate clinically the the patient and the heart rate in 3 days. If clinical and heart rate stability (below 90 bpm), the patients will withdraw the beta-blocker and will be assessed by CPET at 15-day.

After second CPET, the patient will introduce the half-dose of beta-blocker and will be evaluated in 3 days. If clinical stability, the patient will introduce the previous dose of beta-blocker A third CPET will be performed at 15-day

Controlled withdrawal of previos doses of beta-blockers after diagnosis of chronotropic incompetence

Cardiopulmonary Exercise Testing (CPET) and Controlled Withdrawal of Beta-blockers Patient will be assessed for chronotropic incompetence by CPET.If the patient exhibits chronotropic incompetence, a cardiologist will evaluate clinically the patient and the heart rate in 3 days and will be assessed by CPET at 15-day.

After second CPET, the patient will reduce half dose of previous beta-blocker. A cardiologist will evaluate clinically the the patient and the heart rate in 3 days. If clinical and heart rate stability (below 90 bpm), the patients will withdraw the beta-blocker and will be assessed by CPET at 15-day.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximal functional capacity
Time Frame: The change in peak oxygen consumption will be measured at baseline, at 15-day and at 30-day
Maximal functional capacity measured by peak oxygen consumption in the cardiopulmonary exercise testing (CPET). The peak oxygen consumption is expressed in mL/kg/min.The investigators will measure the change of peak oxygen consumption .
The change in peak oxygen consumption will be measured at baseline, at 15-day and at 30-day

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cognitive evaluation
Time Frame: The change in MMSE score will be measured at baseline, at 15-day and at 30-day
We will asses the cognitive function by Mini Mental State Examination (MMSE) The MMSE is a cognitive test. The score is ranged from 0-30 (units of a scale). 30 points is the better outcome. The investigators will assess the change in the score.
