Recruiting studies
- NCT05961488Recruiting
Coronary CT scan after cardiac arrest to check heart artery blockage
This trial tests whether a special CT scan (coronary CT angiography) can help rule out coronary artery disease—the common artery blockage causing heart problems—after someone has survived an out-of-hospital cardiac arrest. It may help doctors quickly decide who needs or does not need further heart procedures.
ReimsAges 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 - NCT06044922Recruiting
Using heart rate to predict brain injury after cardiac arrest
This study looks at how your heart rate changes (heart rate variability) to predict brain injury after a cardiac arrest. It may help doctors identify brain damage earlier so they can provide better care.
Brest, Brittany RegionAges 18 years+ - 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+ - NCT06071910Recruiting
Emergency balloon for cardiac arrest outside hospital
This trial tests if placing a special balloon in the main blood vessel (aorta) can help restart the heart after a cardiac arrest that happens outside the hospital. It is for patients who have not gotten a return of pulse even with CPR.
NorwichAges 18–80 - NCT06122337Recruiting
Finding causes of cardiac arrest in young adults
This study looks at why young adults have a cardiac arrest (when the heart suddenly stops pumping) outside the hospital, with no injury involved. It aims to better understand causes such as heart, genetic, or other medical issues.
TaipeiAges 18–60 - NCT06203847Recruiting
Prehospital drug combo for cardiac arrest
This trial tests whether a combination of three medications (epinephrine, vasopressin, and a steroid) given by paramedics before arriving at the hospital can improve survival for adults who have a cardiac arrest outside of a hospital. It is only for patients who are treated by specially trained paramedics and meet specific medical criteria.
TaipeiAges 18 years+ - NCT06306625Recruiting
Remote conditioning after out-of-hospital cardiac arrest
This trial tests a treatment that uses a blood pressure cuff on your arms to try to protect your brain and organs after your heart stopped outside the hospital. You will be in the intensive care unit, and the study will check if this simple 'remote conditioning' can improve recovery.
BronAges 18–80 - NCT06387225Recruiting
Study on brain recovery after cardiac arrest
This study is trying to find better ways to predict recovery in people who had a cardiac arrest outside the hospital and are still unconscious in the intensive care unit. It may help doctors give more accurate information to families.
La Roche-sur-YonAges 18 years+ - NCT06397417Recruiting
ECMO for refractory cardiac arrest
This study looks at a treatment called ECMO, a machine that does the work of the heart and lungs, to help people whose heart has stopped and does not restart with standard CPR. Researchers want to learn if placing ECMO at the scene can improve survival.
ParisAges 18 years+ - NCT06473207Recruiting
Can a blood pressure cuff protect the brain after cardiac arrest?
This trial tests if a special blood pressure cuff (like a tourniquet) placed on the leg can protect the brain after a cardiac arrest. It is for patients who are unconscious and on a breathing machine after their heart restarts.
Toulon, VarAges 18 years+ - 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.
ViennaAges 18 years+ - NCT06511999Recruiting
Measuring brain oxygen after cardiac arrest
This study tests a special sensor placed in a neck vein to continuously measure oxygen levels in the blood returning from the brain after cardiac arrest. The goal is to help doctors better understand and protect brain function during recovery in the ICU.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06530433Recruiting
Community first responder app trial in Singapore
This trial tests a new way to send trained community first responders to medical emergencies using the myResponder® app. It aims to see if faster help from nearby volunteers can improve outcomes for people in need.
Singapore, SigaporeAges 21 years+ - NCT06538155Recruiting
Using smartwatch data to predict cardiac arrest
This trial uses data from smartwatches and smartphones to better predict and recognize cardiac arrest. If you are a healthy volunteer or have had a heart event, your device data could help improve emergency care.
MilanAges 18 years+ - NCT06564675Recruiting
Using EEG brain waves to predict recovery after cardiac arrest
This trial uses a special EEG device (Brainstatus) to measure brain activity in people who are still unconscious after a cardiac arrest. The goal is to see if certain brain waves can predict a good recovery.
HelsinkiAges 18–110 - NCT06567912Recruiting
TEE training with AI assessment for emergency doctors
This study is creating a training program and an AI-powered tool to help emergency physicians learn how to use TEE, a type of ultrasound that looks at the heart. It's for doctors who want to improve their skills in this area.
TaipeiAges 18–99 - NCT06672159Recruiting
Double shock for out-of-hospital cardiac arrest
This trial tests a new way of giving two quick shocks to restart the heart in people who have a cardiac arrest outside the hospital. If you had a shockable heart rhythm, this approach might help improve your chances of survival.
TrondheimAges 18 years+ - NCT06672315Recruiting
Using a heart ultrasound for cardiac arrest outside the hospital
This study uses a special ultrasound probe placed in the esophagus to look at the heart during cardiac arrest happening outside the hospital. The goal is to see if this test can help doctors make better decisions for treatment.
New Taipei CityAges 18 years+ - NCT06680869RecruitingPhase 3
Early amiodarone for shockable cardiac arrest
This trial tests whether giving the heart rhythm medicine amiodarone early after a shockable cardiac arrest improves survival. If you had a cardiac arrest due to a heart rhythm problem that didn't stop after the first shock, this study may be for you.
Portland, OregonAges 18 years+ - NCT06744361RecruitingPhase 2
Ketamine after cardiac arrest to protect the brain
This trial tests whether the sedative drug ketamine, given after a cardiac arrest, can help protect the brain. It's for people whose heart stopped outside the hospital due to a shockable rhythm and who needed a breathing tube placed by emergency responders.
CopenhagenAges 18 years+ - NCT06781892Recruiting
Defibrillation strategies for cardiac arrest outside the hospital
This trial tests different ways of using defibrillators to restart the heart in people who have a cardiac arrest outside a hospital. It compares two defibrillator machines used together to see if one approach works better for shockable heart rhythms.
AalborgAges 18 years+ - NCT06835491RecruitingPhase 3
Amiodarone to prevent heart rhythm problems after cardiac arrest
This trial tests whether giving the drug amiodarone early can prevent dangerous heart rhythm problems in patients who survived a cardiac arrest with a shockable rhythm. If it works, it could help more people recover.
