SPironolactONe for the Maintenance of Sinus Rhythm in Patients With Atrial Fibrillation

Plain-language summary
Introduction:
There is evidence that aldosterone and the activation of its receptor, mineralocorticoid receptor (MR), promote cardiac fibrosis and electrical disturbances. clinical data suggest that MRAs could have positive effects on AF burden, but some inconsistent results have been reported.
Therefore, investigators propose to perform a randomized, multicenter, open blinded end-point (PROBE) study to evaluate the efficacy of spironolactone on AF recurrence in hypertensive patients with preserved LVEF.
Materials and methods:
SPONSoR trial will be a multicenter, landmark, randomized, open blinded end-point (PROBE) trial of the MRA, spironolactone, in 580 hypertensive patients referred for AF with preserved LVEF.
580 patients will be randomized in a 1:1 ratio to either receive oral spironolactone once daily on top of standard therapy or standard therapy alone, started the day of randomization and continued for 12 months. Spironolactone will be start at 25 mg per day initially then titrated to a maximum of 50 mg per day in the absence of contraindication at the 1-month study visit. AF detection will be provided by the use of a wearable optical photoplethysmography (PPG) device (ScanWatch 42mm®, Withings) throughout the duration of the study. These wearables optical PPG devices (ScanWatch 42mm®, Withings).
The trial duration is 3 years (24 months for inclusion with 12 months of follow-up; total duration participation for the patient of 12 months).

Inclusion Criteria:
* Male or female (since spironolactone is not recommended during pregnancy and breastfeeding, a highly sensitive pregnancy test (serum HCG) will be systematically carried out in women of childbearing age and information will be given to non-pregnant women at the time of inclusion to instruct them to use an effective method of contraception during all the study period. Effective methods include: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, transdermal, or progestogen-only hormonal contraception associated with inhibition of ovulation : oral, injectable, implantable, or intrauterine device, or intrauterine hormone-releasing system, or bilateral tubal occlusion or vasectomised partner, or sexual abstinence)
* Age \> 18 years
* Hypertension defined as current use of anti-hypertensive drugs for more than 12 months
* Paroxysmal or no long-standing persistent AF (as defined by the ESC guidelines) with at least 1 episode within the preceding 6 months
* Sinus rhythm at enrolment
* Patient signed consent
* Willing to comply with scheduled visits, as outlined in the protocol
* French speaking
* Recipients of the social security regime
Exclusion Criteria:
* Contraindications to spironolactone therapy: pregnancy, breastfeeding, intolerance, hyperkalemia (\>5.0 mmol/L), severe renal dysfunction (defined as an estimated glomerular filtration rate (eGFR) \< 30 ml/min/1,73m² (per the C…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
