LundAges 18 years+ - NCT05841056RecruitingPhase 3
Short amiodarone treatment to prevent new heart rhythm after surgery
This trial studies whether a short course of amiodarone started right after heart surgery can reduce problems from new-onset atrial fibrillation (a common fast heart rhythm) or flutter. It may help some patients avoid ongoing rhythm issues and improve recovery soon after discharge.
Hamilton, OntarioAges 18 years+ - NCT07727681RecruitingPhase 4
Statins to Prevent Atrial Fibrillation After Lung Surgery
This trial tests whether taking a statin before and after lung surgery can prevent a common heart rhythm problem called atrial fibrillation (AFib). If you are 60 or older and having a lung segment or lobe removed, this study may help you avoid AFib after your operation.
BeijingAges 60 years+ - NCT07295769Recruiting
Detecting hidden atrial fibrillation after stroke of unknown cause
This study uses a small patch (M.E.M.O. Patch) to continuously monitor your heart rhythm for hidden atrial fibrillation, a treatable cause of stroke. The goal is to see if the patch can find irregular heartbeats that standard tests might miss.
Seoul, Songpa-guAges 19 years+ - NCT04804748Recruiting
DefiPace to help prevent heart rhythm problems after heart surgery
This study tests DefiPace in people who are having planned open-chest heart surgery (bypass and/or valve surgery) to see if it can help reduce certain post-surgery heart rhythm complications. Whether it’s usable depends on your planned procedure and specific health factors.
ViennaAges 18 years+ - NCT06828939Recruiting
