Combined, the two diseases negatively influence each other's prognosis and lead to higher mortality. Studies in HF patients in which the AF burden is reduced by AF ablation show promising results toward improved prognosis, but so far only one randomized trial is conducted that focused on major clinical endpoints. As the selected patients in this trial were not representative for the entire population and its ablation method varied from patient to patient, it is the aim of the present study to confirm that early invasive therapy consisting of a strict pulmonary vein isolation (PVI) protocol using cryoballoon therapy has positive effects on hard clinical endpoints in a wider variety of patients in the HF population.\n\nFurthermore, there are no studies which compare cost-effectiveness of an early invasive strategy in this patient category. The investigators expect that avoided hospitalizations and healthcare resource utilizations lead to lower costs in the AF ablation group, despite initial higher costs of the procedure.\n\nObjective:\n\nTo compare outcome and cost-effectiveness of early AF ablation by PVI using cryoballoon therapy with standard (medical) therapy in patients with heart failure with reduced ejection fraction.\n\nStudy design:\n\nMulticenter, randomized, open label clinical trial.\n\nStudy population:\n\nSymptomatic adult patients with heart failure with reduced ejection fraction (\\<40%) and paroxysmal or persistent AF.\n\nIntervention:\n\nAF ablation (PVI) using cryoballoon therapy.\n\nOutcome measures:\n\nThe primary endpoint is a combined endpoint of all-cause mortality, unplanned cardiovascular hospitalization, and stroke (time-to-event analysis).\n\nSecondary endpoints of the trial are:\n\n* A combined endpoint of mortality, number of unplanned cardiovascular hospitalizations, and stroke (recurrent-event analysis);\n* A hierarchical endpoint of mortality, unplanned cardiovascular hospitalizations, stroke, and HF complaints;\n* Cost-effectiveness. Key exploratory endpoints include individual components of the combined endpoints, days alive out of the hospital, hospitalizations for heart failure, recurrence of atrial arrhythmia, and quality of life."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients aged 18-80;\n* HF with ejection fraction \\<40%, as assessed by recent (\\<6 months) echocardiography or cardiovascular magnetic resonance imaging (CMR);\n* AF, documented on standard ECG or Holter monitoring;\n* Eligible for both treatment arms;\n* Signed and dated informed consent prior to admission to the trial.\n\nExclusion Criteria:\n\n* End-stage heart failure: NYHA class IV, patients on waiting list for cardiac transplant and/or left ventricular assist device;\n* Long-standing (\\> 1 year) persistent or permanent AF;\n* Previous pulmonary vein isolation or surgical ablation;\n* Left atrial diameter ≥60 mm or left atrial volume index ≥50 ml/m2;\n* Impaired renal function, defined as estimated glomerular filtration rate (eGFR) ≤25 ml/min/1.73m2;\n* Recent (\\<90 days) acute coronary syndrome, cardiac intervention1, or stroke/transient ischemic attack (TIA);\n* Planned or expected cardiac surgery in the following year;\n* Active infectious disease or malignancy;\n* Women who are pregnant or planning to become pregnant during the trial;\n* Contraindication for cryoballoon ablation or other condition that may prevent subjects from adhering to the trial protocol, in the opinion of the investigator.'}, 'identificationModule': {'nctId': 'NCT04342832', 'acronym': 'RACE-8-HF', 'briefTitle': 'Cryoballoon Ablation Versus Medical Therapy in Patients With Heart Failure and Atrial Fibrillation', 'organization': {'class': 'OTHER', 'fullName': 'Maastricht University'}, 'officialTitle': 'CRyoballoon Ablation Versus mediCal thErapy in Patients With Heart Failure and Atrial Fibrillation: A Multicenter Randomized Clinical Trial, the RACE-8-HF Trial', 'orgStudyIdInfo': {'id': 'NL71710.068.19'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Early invasive treatment (cryoballoon ablation)', 'interventionNames': ['Procedure: Cryoballoon ablation']}, {'type': 'NO_INTERVENTION', 'label': 'Standard medical care'}], 'interventions': [{'name': 'Cryoballoon ablation', 'type': 'PROCEDURE', 'otherNames': ['Pulmonary vein isolation', 'PVI', 'CBA'], 'description': "If a patient is randomized to early invasive treatment, the ablation is performed within 3 months by an experienced cardiac electrophysiologist using CE-certified equipment. Via the femoral vein a guiding catheter is advanced through the inferior vena cava to the right atrium and into the left atrium via transseptal puncture. Then, the cryoballoon is advanced, inflated, and placed against one of the four PVs. PV occlusion is assessed by selective contrast injection. When adequate PV antral seal is confirmed, ablation of the tissue in contact with the balloon is performed using pressurized liquid nitrous oxide. The cold inflated balloon thus creates circular lesions around the PV. The balloon and tissue interface are then allowed to reach normal temperatures. Depending on local practice, the freeze-thaw cycle may be repeated twice. Electrical isolation is assessed and when it is confirmed, the next PV is treated in the same way. The procedure ends when all PV's are isolated.", 'armGroupLabels': ['Early invasive treatment (cryoballoon ablation)']}]}, 'contactsLocationsModule': {'locations': [{'zip': '6525 GA', 'city': 'Nijmegen', 'state': 'Gelderland', 'country': 'Netherlands', 'facility': 'Radboudumc', 'geoPoint': {'lat': 51.8425, 'lon': 5.85278}}, {'zip': '6229 HX', 'city': 'Maastricht', 'state': 'Limburg', 'country': 'Netherlands', 'facility': 'Maastricht UMC+', 'geoPoint': {'lat': 50.84833, 'lon': 5.68889}}], 'overallOfficials': [{'name': 'Kevin Vernooy, MD PhD', 'role': 'STUDY_CHAIR', 'affiliation': 'Maastricht UMC+, Radboudumc'}, {'name': 'Michiel Rienstra, MD PhD', 'role': 'STUDY_CHAIR', 'affiliation': 'UMC Groningen'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Maastricht University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
