Inhaled Hydrogen Therapy's Effect on Early Recurrences of Atrial Fibrillation Post-ablation. (H2-FA)
Inhaled Hydrogen Therapy's Effect on Early Recurrences of Atrial Fibrillation Post-ablation. Phase II, Multicenter, Randomized, Controlled, Open-label Clinical Trial
The goal of this clinical trial is to testing the perioperative inhaled hydrogen (H2) administration's effects during atrial fibrillation ablations (AF) to reduce both early and late recurrences associated with this procedure.
Researchers will compare H2 inhalation to the standard of care to see if we observe a reduction in AF recurrence after ablation but also a reduction in rehospitalizations or emergency visits for cardioversion, and consequently an improvement in quality of life.
Participants will:
- have an AF ablation associated to an hydrogen therapy or standard of care
- complete quality of life questionnaires
- record ECG on KardiaMobile©
- Keep a diary of their symptoms
- have a blood test
- have 2 follow-up visits (after 3 and 12 months) and 2 phone calls (after 6 and 9 months)

Effectiveness of inhaled hydrogen therapy on early recurrences of atrial fibrillation post-ablation and on the improvement of quality of life at 3 months
大体时间:From baseline (before ablation) to 3 months after ablation

Composite binary endpoint, reported as the number of participants meeting both criteria: (1) no early recurrence during the blanking period (first 3 months after ablation), where recurrence is defined as any episode of atrial fibrillation, atrial flutter or atrial tachycardia lasting at least 30 seconds; AND (2) improvement in quality of life, defined as an improvement in quality of life, defined as an increase of at least 5 points in the AFEQT overall score (range 0-100; higher scores indicate better quality of life) between baseline and 3 months. |
