Paris, FranceAges 18 years+ - NCT03981107Recruiting
Hands-only CPR vs standard CPR after witnessed cardiac arrest
This study compares two ways of doing CPR for adults who collapse outside the hospital and are not breathing normally: hands-only CPR versus standard CPR. The goal is to see which approach improves survival after witnessed cardiac arrest.
BergamoAges 18 years+ - NCT03790943Recruiting
Health study of heart problems in childhood cancer survivors
This study follows people who had cancer as children to learn about heart-related changes years after treatment. It may help doctors better understand who is at risk and how to monitor the heart in long-term survivors.
Basel, Canton of Basel-CityAges 18 years+ - NCT03222999Recruiting
Study of out-of-hospital cardiac arrest patients in Korea
This trial is for people whose heart stopped outside the hospital and who received emergency resuscitation, where emergency doctors believed it was caused by a heart problem. The goal is to learn how to better treat or manage this type of cardiac arrest.
SeoulAges Any age - NCT02316314Recruiting
Study heart scan and function in people with Friedreich’s ataxia
This study uses heart tests (including ultrasound and MRI) to better understand how Friedreich’s ataxia affects the heart. You might benefit by getting detailed heart evaluation and contributing to research that could guide future care.
New York, New YorkAges 12–50 - NCT07287423Recruiting
A study of a new pacemaker system for heart rhythm problems
This trial tests a new pacemaker system for people who need a pacemaker for a slow or irregular heartbeat. It aims to see if the system is safe and works well.
PragueAges 18 years+ - NCT05376267Recruiting
Testing how long cooling lasts after pediatric cardiac arrest
This study tests whether using body cooling for different lengths of time helps children recover better after an out-of-hospital cardiac arrest. It focuses on children who remain very unresponsive after resuscitation and need a breathing tube and steady temperature control.
Birmingham, AlabamaAges 2 days–17 years - NCT05868616Recruiting
Checking heart resynchronization timing with a noninvasive test
This trial evaluates a noninvasive way to assess who should get Cardiac Resynchronization Therapy (CRT), and to check results after implantation. If you fit the heart rhythm and heart pump criteria, the approach may help confirm whether CRT is appropriate for you.
OsloAges 18–80 - NCT03393169Recruiting
Tracking complications after heart surgery in adults
This study looks at how often and why complications happen after heart surgery, using information from the hospital stay. It may help improve care by understanding postoperative risks and outcomes.
ParisAges 18 years+ - NCT03594318Recruiting
Registry for adults treated in ICU after cardiac arrest
This trial is a registry, which means the researchers collect information about people who were treated in an intensive care unit after a cardiac arrest. It may help improve understanding of outcomes and care, which can guide future treatment.
Le ChesnayAges 18 years+ - NCT03360227Recruiting
Registry after heart device implantation planning
This is a registry study that records information from people before they get a heart-related device implanted. It may help doctors understand how the team’s tests and planning relate to the procedure and outcomes later on.
DüsseldorfAges 18–80 - NCT04973579Recruiting
Stent plus heart surgery for high risk carotid patients
This trial looks at whether doing carotid artery stenting at the same time as heart surgery is safe and effective for people at high risk of stroke around the time of surgery. It targets people with significant carotid narrowing who also need heart surgery for specific heart problems.
KrakowAges 18 years+ - NCT02814942Recruiting
Testing CRT in people with weak hearts and wide ECG signals
This study looks at whether a device called CRT (Cardiac Resynchronization Therapy) can help people with heart failure who have a weak heart pumping strength and a “wide” electrical signal pattern on an ECG. It may help some people feel better and improve heart function, especially if they are not already on the best standard medicines.
SingaporeAges 18 years+ - NCT04330651Recruiting
Extra-support machine for heart patients after surgery
This study looks at using an external life-support machine after heart surgery. It may help patients who need temporary extra support while the heart and body recover.
