Beta-blOckers discoNtinuation in Patients Presenting Heart FaIlure With REcovered Left Ventricular Ejection Fraction

Recruiting now · Phase 3

Conditions studied: Heart Failure

In brief

A significant proportion of patients initially diagnosed with heart failure and a reduced left ventricular ejection fraction (LVEF\<40%, HFrEF) presents a substantial improvement in response to evidence-based medical and device therapies. Some of these patients (estimated from 20 to 30%) even display a complete normalization of LVEF (i.e., \>50%) and are now recognized as a specific sub-group of patients named Heart Failure with recovered Ejection Fraction (HFrecovEF). Different studies have shown that reverse remodeling with recovery of cardiac function and stabilization of HF symptoms are associated with improved clinical outcomes over the long-term. Whether these patients present a stable remission of HF and could benefit a therapeutic de-escalation is however unclear. Until novel data are provided, medical therapies are thus continued indefinitely in these stable patients with HFrecovEF. Current guidelines for the management of patients with heart failure and a reduced left ventricular ejection fraction recommends a comprehensive therapy, including 5 different therapeutic classes (RAAS blockers (with a preference for ARNi) + Beta-Blockers + SGLT2i + Mineraloreceptors Antagonists + or - Diuretics ). None of these therapies (with the recent exception of one SGLT2i, i.e. Dapagliflozin) have been tested in patients with HFrecovEF. In addition, it is unclear whether the benefit of older therapies (notably beta-blockers) remains in patients receiving modern comprehensive therapy as newer drugs were tested as add-on therapies. This polypharmacy is lowering adherence and is creating a challenge for physicians and patients. Betablockers are notably associated with frequent side effects, a limited tolerance and a significant reduction of quality of life. Their efficacy on outcomes is not established in patients with normal LVEF. Pilot studies have suggested that Beta-blockers interruption in patients with HF and normal EF was associated with functional improvement.

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age ≥ 18 years-old
Established diagnosis of HF for more than 12 months, from an ischemic or a non-ischemic origin
With a documented history of reduced left ventricular ejection fraction (LVEF ≤ 45%), followed by a normalisation of LVEF (≥ 50 % for the last 6 months) assessed by cardiac echography.
With a left ventricular end diastolic volume indexed to body surface area (LVEDVi) within the normal range (≤74ml/m2 in men and ≤61 ml/m2 in women)
No or mild symptoms of HF (defined as NYHA functional class I or II)
No heart failure-related hospital admission within the last six months
Currently receiving a beta-blocker indicated for chronic heart failure (i.e. bisoprolol or carvedilol or metoprolol or nebivolol) whatever the dose used, for at least 12 months
And receiving the guideline-directed optimal medical therapy for at least 12 months (i.e., maximal tolerated dose of SGLT2 inhibitors, and of RAAS blocker (Angiotensin receptor neprilysin inhibitor OR Angiotensin-converting-enzyme-inhibitors OR Angiotensin II receptors blockers), and MRA if tolerated). Loop diuretics use is adjusted to congestive signs according to physicians' decision.
No initiation or major adjustment in heart failure therapies should have occurred during the 3 months prior to study inclusion.

Cardiac resynchronization therapy
Extra-cardiac conditions requiring beta-blockers (migraine, essential tremor, prevention of bleeding from esophageal varices in patients with liver cirrhosis, adrenergic symptoms of hyperthyroidism…) according to investigator decision.
