Recruiting studies
- 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 - NCT04446585Recruiting
Study of early help for witnessed home cardiac arrests
This study looks at witnessed sudden cardiac arrest happening in residential areas, and tests whether a new first-responder approach gets help to people faster. It may help improve outcomes after cardiac arrest by improving the timing and coordination of emergency response.
Ballerup Municipality, The Capital RegionAges 8 years+ - 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+ - NCT07829887Recruiting
Measuring brain oxygen after cardiac arrest
This study tests a device that measures oxygen levels in the brain during recovery from cardiac arrest. It aims to see if monitoring brain oxygen helps doctors make better treatment decisions after the heart restarts.
Calgary, AlbertaAges Any age - 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 - NCT07649616Enrolling by invitation
Training Law Enforcement to Use Heart-Restart Devices
This study helps police officers learn to use automated external defibrillators (AEDs)—machines that can restart a stopped heart during cardiac emergencies. The goal is to increase how often these devices are used and improve survival rates when officers respond to cardiac arrest calls.
Detroit, MichiganAges 18 years+ - NCT07596446Recruiting
Emergency treatment study for cardiac arrest patients
This study tests emergency treatments for people who have had a cardiac arrest (heart stops beating) outside the hospital. It looks at two groups: people whose hearts stop despite CPR efforts, and people whose hearts have restarted. The goal is to see if these treatments can help patients survive and recover better.
PragueAges 18–70 - 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+ - NCT07564778Recruiting
Pain Management After Cardiac Arrest Recovery
This study examines how to better treat pain in patients who have survived cardiac arrest and are unconscious in the hospital. Researchers want to understand pain experiences and test pain-relief strategies during early recovery.
HalmstadAges 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+ - NCT05895838RecruitingPhase 3
Trial for medicines after out-of-hospital cardiac arrest
This Phase 3 trial studies treatments given after a person survives an out-of-hospital cardiac arrest to improve recovery and survival. It is for patients who stay unconscious for a short time after circulation returns, and who meet safety conditions.
Copenhagen, Capital Region of DenmarkAges 18 years+ - 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+ - NCT07438938Recruiting
Lazarus airway opening index trial for cardiac arrest
This study looks at a new measure called the Airway Opening Index (AOI) to see if it can help doctors predict when a person's airway opens during CPR after a heart attack outside the hospital. If you've had a cardiac arrest and needed a breathing tube, this research might help improve how care is given.
Ghent, East-FlandersAges 18 years+ - NCT07431710Recruiting
AI-guided chest compressions for cardiac arrest in the ER
This trial tests whether artificial intelligence (AI) can help doctors give better chest compressions during CPR for adults whose hearts stopped outside the hospital. The goal is to improve blood flow and outcomes without using special equipment in the ambulance.
New Taipei City, BanqiaoAges 20 years+ - NCT07421882Recruiting
Cooling after cardiac arrest to improve brain recovery
This trial tests if starting body cooling before reaching the hospital can help protect the brain after a cardiac arrest. It is for adults who are unconscious after their heartbeat has been restored by emergency services.
SingaporeAges 16–80 - 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 - NCT07405229RecruitingPhase 4
Medical treatment for idiopathic ventricular fibrillation patients
This study tests medical treatments for people who survived a cardiac arrest with a specific heart rhythm problem called idiopathic ventricular fibrillation. If your cardiac arrest was likely from a heart issue but not from clogged arteries, you might help find better treatments.
Copenhagen, Dr.Ages 18 years+ - 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+ - NCT07352709Recruiting
Ventilation feedback simulation for EMS crews
This trial tests a simulation tool that gives feedback on ventilation performance. It is designed for currently active EMS professionals to see if the tool improves their skills.
Dallas, TexasAges 18–60 - 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+ - 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 - NCT07323667Enrolling by invitation
Study of a first responder system for cardiac arrest in Zug
This trial is studying a new system where trained volunteers respond quickly to help people whose heart stops outside of a hospital in Zug, Switzerland. The goal is to see if this system improves survival and recovery.
Zug, Canton of ZugAges 18 years+ - NCT05132387Recruiting
