GothenburgAges 16 years+ - NCT04229056Recruiting
Computer training to improve thinking and planning after stroke or Parkinson’s
This trial tests computer-based “self-training” to improve executive function, such as working memory—your ability to hold and use information in mind. It’s for adults with a prior stroke, cardiac arrest, or Parkinson’s disease who have trouble on a specific working-memory task.
CopenhagenAges 18–100 - NCT04493970Recruiting
Study tests a CPR training app for high school students
This trial looks at whether using a required CPR training approach (through instruction and an app) improves learning among high school students. You may be asked to complete a short survey to help researchers understand how well the training is working.
Overland Park, KansasAges 12–25 - NCT04576130Recruiting
ICD study after cardiac arrest from an abnormal heart rhythm
This study looks at an implantable defibrillator (ICD) strategy in people who survived a cardiac arrest caused by an abnormal rhythm (ventricular fibrillation or ventricular tachycardia). It aims to reduce the risk of another dangerous rhythm after the blocked heart arteries are fully treated.
CopenhagenAges 18 years+ - NCT07520877Recruiting
Phone-Guided CPR Training With Automated Device
This study tests whether receiving CPR instructions over the phone with help from an automated external defibrillator (AED)—a machine that can restart the heart—improves the quality of chest compressions people perform. You would practice CPR techniques during a training session.
PécsAges 16 years+ - NCT05135403Recruiting
Registry study for the ASSURE wearable heart defibrillator
This study collects information from adults who have been prescribed the ASSURE wearable defibrillator. The goal is to understand how the device performs in real-world patients after it is approved.
Seattle, WashingtonAges 18 years+ - NCT05166343RecruitingPhase 2/Phase 3
Testing a shot of epinephrine during out-of-hospital CPR
This trial studies whether giving a medicine shot (epinephrine) into the muscle helps children who have a cardiac arrest outside the hospital. It’s meant for emergency situations where CPR is started right away by trained responders.
London, OntarioAges 1 day–17 years - NCT05373498Recruiting
Registry for children’s heart emergencies after resuscitation
This trial is a registry that collects information about children (under 18) who have congenital heart problems and need resuscitation with chest compressions. It helps doctors understand these emergencies and may improve future care for similar patients.
Leipzig, SaxonyAges Up to 18 years - NCT05520762Recruiting
Trial for patients after in-hospital cardiac arrest needing breathing support
This trial studies a hospital treatment for people who have a cardiac arrest while in the hospital and still need help breathing. It may help improve care right after this emergency by testing an airway resuscitation approach.
New York, New YorkAges 18 years+ - NCT05545176Recruiting
Testing rules for stopping resuscitation after out-of-hospital arrests
This trial studies and checks decision rules doctors can use to decide when to stop CPR in patients who have an out-of-hospital cardiac arrest. It may help make those decisions more consistent and safer across Asian countries.
TaipeiAges 18 years+ - NCT05574296RecruitingPhase 1
Test hydrogen gas for children needing emergency heart resuscitation
This early safety study tests whether “hydrogen” can be given to children during emergency heart resuscitation that isn’t improving with standard efforts. It’s meant to see if the treatment is safe and feasible for a very specific, life-threatening situation.
Washington D.C., District of ColumbiaAges Any age - NCT05588024Recruiting
Device-assisted CPR with head and chest elevation during arrest
This trial studies a CPR method that uses a device to help raise the head and chest during active resuscitation after cardiac arrest. It may help guide whether this technique improves outcomes for people who are not breathing normally and do not have a pulse.
Minneapolis, MinnesotaAges 18 years+ - NCT05631730RecruitingPhase 3
Flecainide plus metoprolol vs metoprolol alone for rhythm control
This trial studies whether adding flecainide to metoprolol can better reduce dangerous heart rhythm problems in people with mitral valve prolapse. It also checks safety and side effects compared with metoprolol alone.
OsloAges 18 years+ - NCT05706194Recruiting
Early brain prognosis test after out-of-hospital cardiac arrest
This trial studies how to predict brain recovery early after a non-traumatic out-of-hospital cardiac arrest. The goal is to help clinicians estimate outcome sooner, which may improve decision-making during intensive care.
HelsinkiAges 18–100 - NCT05961748Recruiting
Brain and heart illness registry for adults in China
This study is a registry that collects health information from adults who have certain new heart and/or brain conditions. It may help researchers understand how these problems occur together and improve future care planning.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05969028Recruiting
Testing breathing and chest compression timing for out-of-hospital cardiac arrest
This trial studies the best timing for chest compressions and airway management for adults who have sudden cardiac arrest outside the hospital. It may help improve survival chances by guiding first EMS responders on how to act sooner and more consistently.
Seattle, WashingtonAges 18 years+ - NCT06025123Recruiting
Cooling treatment for cardiac arrest before hospital
This trial tests whether cooling the brain through the nose right after a cardiac arrest improves survival. Paramedics will start a cooling treatment within 20 minutes of arriving, and it may help protect your brain while you are unconscious.
ViennaAges 18–79 - NCT06067204Recruiting
Automatic breathing machine during cardiac arrest
This trial tests if using an automatic ventilator during CPR for out-of-hospital cardiac arrest helps with survival. It aims to find better ways to manage breathing support in emergencies.
HsinchuAges 18 years+ - NCT06207942Recruiting
Extended follow-up for cardiac arrest survivors and caregivers
This study follows up on survivors of out-of-hospital cardiac arrest who were already in the STEPCARE trial. It also looks at the well-being of their main caregiver (like a family member or close friend) to see how everyone is doing over time.
BrisbaneAges 18 years+ - NCT06455514RecruitingPhase 1
Magnesium to protect the brain after cardiac arrest
This study tests if giving magnesium soon after a cardiac arrest can protect the brain and improve recovery. It is for adults who have been brought back to life after a heart stoppage.
New York, New YorkAges 18–85 - NCT06491186Recruiting
Pulse check using ultrasound during cardiac arrest
This trial tests whether using an ultrasound on the groin area can quickly check for a pulse in people who have had a cardiac arrest outside the hospital. It may help emergency responders make faster decisions during resuscitation.
