Brief Summary

New onset heart failure (HF) is observed in up to 25% of patients with incident atrial fibrillation or flutter (AF). Current guidelines suggest that both conditions (AF & HF) be addressed with guideline directed medical therapy (GDMT) for HF and rate or rhythm control of AF. Hence, patients with both conditions are subjected to extensive polypharmacy with possible prognostic benefits, but also possible side effects, such as decreased renal function, dizziness, tiredness and hypotension, as well as the financial burden on both the individual patients and society, in addition to the stigma of having a HF diagnosis.

Guidelines do not inform how to manage long-term patients with HF, who following control of the incident tachycardia (e.g. AF), show full recovery from their HF condition.

This investigator-initiated, open-label, randomized, non-inferiority trial will test whether incremental weaning of GDMT in patients following full cardiac recovery and AF control is non-inferior compared to continuous GDMT with respect to the primary endpoint of freedom from heart failure deterioration. Furthermore, this study seeks to extensively phenotype these patients (genetic testing, advanced imaging, biomarkers etc.) in order to establish whether certain phenotypes are at lesser or greater risk of deterioration once remission is established. This novel approach of a personalized treatment regimen depending on e.g. genetic profiling could lead to an aggressive treatment in patients at high risk of deterioration and conversely spare patients with a negligible risk, a life-long intensive treatment regimen.

All HF clinics located in Zealand, Denmark, with a catchment area of >2 million citizens, have agreed to participate in the WEAN-HF trial. A total of 348 patients will be randomized. Patients are followed up the 1st year after randomization with clinical examination, biomarkers and echocardiography, and are subsequently followed via Danish nationwide registries for 10 years.

Detailed Description

Background:

Heart failure (HF) is a disease that affects more than 60000 patients in Denmark and millions across the world. The prognosis of HF is comparable to many types of cancer. New onset HF is observed in up to 25% of patients with incident atrial fibrillation or flutter (AF). The persistent tachycardia caused by AF is believed to exert the heart to a point where it causes HF. Whether AF is the cause of HF, or conversely that the detrimental effects of HF has induced AF, is difficult to ascertain upon the initial presentation. Current guidelines suggest that both conditions (AF & HF) be addressed with guideline directed medical therapy (GDMT) for HF and rate or rhythm control of AF. GDMT for HF consists of at least 4 different types of medication which is combined with management for AF (anticoagulant and often antiarrhythmic medication or ablation procedures). Hence, patients with both conditions are subjected to polypharmacy with at least 6 different types of medication in addition to their usual medication regimen. This may have prognostic benefits, but also possible side effects, such as decreased renal function, dizziness, tiredness and hypotension, as well as the financial burden on both the individual patients and society, in addition to the stigma of having a heart failure diagnosis.

Gaps in knowledge Data are lacking on how to optimally manage patients long-term with heart failure suspected to be tachycardia-induced, who following cessation or control of the incident AF, show full recovery from their heart failure condition. Guidelines do not suggest whether GDMT for heart failure should continue lifelong, cease or be weaned. In the TRED-HF study, 51 non-ischemic HF patients with LVEF recovery who were seemingly clinically stable were weaned from GDMT. Approximately 40% of patients showed signs of deterioration after 6 months of incremental GDMT weaning. Where TRED-HF patients had verified longstanding chronic HF, the situation for patients experiencing an incident episode of AF subsequently leading to acute heart failure may represent a different phenotype with a better prognosis once AF is terminated or controlled as suggested by observational data. Currently there is no data supporting how to manage GDMT in this population of heart failure patients with recovery following control of their AF episode.

Objective:

To observe whether incremental weaning of GDMT in patients following full cardiac recovery and AF control is non-inferior compared to continuous GDMT.

Furthermore, using an extensive phenotypic profiling, to investigate if one or more biomarkers can predict which patients are at an increased risk of cardiac deterioration in both intervention groups.

Hypothesis:

The investigators hypothesize that patients weaned from GDMT will experience similar rates of deterioration as patients on continuous GDMT.

Perspective The chance of remission after a heart failure diagnosis differs greatly depending on the etiology of heart failure. Although dramatic differences in remission rates depending on etiology have been established, patients with heart failure are in general committed to the same regimen of GDMT. For example, in patients with alcohol-induced heart failure, removing the cardiotoxic substance (alcohol) through abstinence leads to recovery in >50% of cases. Genetic profiling reveals that changes in mutations leading to alterations in cardiac structural proteins - titin - are very prevalent in patients with alcohol-induced heart failure. It appears that patients may be at increased risk of heart failure if they both have a genetic disposition combined with a cardiotoxic stimulus (e.g. alcohol, tachycardia). Interestingly, mutations in the same titin gene has also been found in many patients with atrial fibrillation. Therefore, it is plausible that if the detrimental effects of prolonged tachycardia could be stopped a continuous HF remission in our cohort would be observed. This study seeks to extensively phenotype patients with tachycardia-induced heart failure in order to establish whether certain phenotypes are at lesser or greater risk of deterioration once remission is established. This novel approach of a personalized heart failure treatment regimen depending on genetic profiling and advanced imaging could lead to an aggressive treatment in patients at high risk of deterioration and conversely spare patients with a negligible risk of deterioration a life-long intensive treatment regimen.

Primary endpoint:

Patients free from heart failure deterioration 1 year after randomization

Secondary endpoints 1 year after randomization:

• Changes in Minnesota Living with Heart Failure Questionnaire from baseline (min. score 0 - max. score 105, where higher scores indicates worse quality of life)
• Hospitalization for heart failure
• Cardiovascular (CV) hospitalizations
• Non-CV hospitalizations
• CV death
• All-cause death
• Patients in need of initiation of loop diuretics or doubling of dosage
• Changes in N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) from baseline
• Patients needing changes in medication for AF (uptitration of current medication or change in/addition of new medication) or re-do ablation for AF
• Patients with signs of AF that persistently exceed 110 bpm despite best practice Adverse events will be summarized;
• Patients with renal deterioration, hypotension, dizziness.
• Patients with signs of new onset liver affection and/or thyroid dysfunction

Methods:

This is an investigator-initiated, open-label, randomized, non-inferiority trial. This clinical trial complies with the Declaration of Helsinki, modified in 2013. This study has been approved by both the ethical committee (H-23010220) and the Knowledge Centre on Data Protection Compliance in the Capital Region of Denmark (P-2023-111). This trial will adhere to good clinical practice guidelines (GCP).

Patients with HF who are followed in HF clinics on Zealand including the greater Copenhagen region are screened. This area covers >2 million citizens (approximately 1/3 of all citizens in Denmark). All patients fulfilling criteria for participation will be invited to participate. HF specialists at each HF clinic will assess eligibility based on a review of the medical chart and an individual assessment. Patients can be rescreened for inclusion repeatedly throughout the inclusion period.

Collaborators:

This trial is executed, analyzed and published by the main applicant and nested at Herlev-Gentofte Hospital. A collaboration between the applicant and heart failure clinics is pivotal in order to ensure timely inclusion of a generalizable heart failure population and to swiftly implement the findings into clinical practice.
