Montpellier, HéraultAges 18 years+ - NCT05218278Recruiting
Nerve and brain signals after out-of-hospital cardiac arrest
This study looks at measurements taken after someone survives an out-of-hospital cardiac arrest to see if the results can predict outcomes. It may help doctors understand which patients are likely to do better and guide care in the ICU.
MariborAges 18 years+ - NCT05227053Recruiting
Cryoablation study for paroxysmal atrial fibrillation after approval
This study looks at outcomes after a specific heart procedure called pulmonary vein isolation done with a cryoablation catheter. It is for adults with symptomatic “paroxysmal” atrial fibrillation who are planning this exact procedure.
Anchorage, AlaskaAges 18 years+ - NCT05242419Recruiting
Huperzine A to reduce confusion after non-heart surgery
This trial studies whether a medicine called huperzine A can reduce “postoperative delirium,” which is sudden confusion after surgery, in older adults. It focuses on people having non-heart surgery under general anesthesia for at least two hours.
Wenzhou, ZhejiangAges 75 years+ - NCT05258448Recruiting
Chemo-radiotherapy for advanced, non-surgical lung cancer
This trial studies treatment that combines chemotherapy and radiation for people with advanced lung cancer that cannot be removed with surgery. It may help improve cure chances for patients who can complete the study tests, including heart scans.
Odense CAges 18 years+ - NCT05326828Recruiting
Implant monitor to find hidden atrial fibrillation after heart injury
This study tests whether an implantable heart rhythm monitor can detect atrial fibrillation (an irregular heartbeat) in people who had a type of heart attack with non-obstructed arteries. The goal is to find a possible reason for the event so doctors can treat it appropriately.
BernAges 18–85 - NCT05327062Recruiting
Noninvasive mapping to guide a heart resynchronization device
This trial tests a noninvasive way to map your heart’s wiring and veins to help guide placement of a heart resynchronization therapy (CRT) device. If you have certain abnormal heart rhythm and weak heart pumping, it may help doctors place the therapy more accurately and safely.
Chicago, IllinoisAges 18 years+ - NCT05373940Recruiting
ICD placement to prevent sudden heart death in people over 70
This study looks at placing an ICD, a device that can stop dangerous heart rhythms, to help prevent sudden cardiac death. It is for people over 70 with specific heart function and heart failure symptoms.
Aix-en-ProvenceAges 70 years+ - NCT05391737Recruiting
Study of fluid in the lungs after open-water swimming
This study looks at what happens in the lungs after open-water swimming. It may help doctors better understand and recognize “swimming-induced lung fluid,” especially by using lung ultrasound when symptoms happen.
FalunAges 18 years+ - NCT05465031RecruitingPhase 4
Testing heart-protection medicine during breast cancer treatment
This trial tests sacubitril/valsartan to help prevent heart weakness (cardiotoxicity) caused by breast cancer treatments like anthracyclines and/or anti-HER2 drugs. If you qualify, you may be offered this heart-protection medicine while your cancer is treated.
Opole, Opole VoivodeshipAges 18 years+ - NCT05480319Recruiting
