Pasadena, CaliforniaAges 18 years+ - NCT06776549Recruiting
Cooling or normal temperature after cardiac arrest with ECMO
This trial tests if cooling the body (hypothermia) or keeping normal body temperature (normothermia) after emergency heart-lung support (ECMO) improves survival in adults who had a cardiac arrest outside the hospital.
Kurume, FukuokaAges 18–75 - NCT07002294Recruiting
Specialist care after cardiac arrest recovery trial
This trial tests whether care from a specialist team helps people recover better after a cardiac arrest outside the hospital. If you were revived and brought to the emergency department with a pulse, you might be eligible.
Pittsburgh, PennsylvaniaAges 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 - NCT03261089Recruiting
Predicting brain outcome after cardiac arrest, reducing bias
This study looks at how to predict brain recovery after certain types of cardiac arrest. It aims to improve decision-making so people are not misjudged due to “self-fulfilling prophecy.”
San Francisco, CaliforniaAges 18–89 - 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+ - NCT04675918Recruiting
Registry for children’s in-hospital cardiac arrest
This study collects information about children (from 1 month to 18 years) who have a cardiac arrest while in the hospital. The goal is to better understand what happens during these emergencies and improve care in the future.
MadridAges 1 month–18 years - NCT04972526Recruiting
Registry for adult patients who get an ultrasound heart scan in ICU
This study is a registry, meaning it collects information from adult patients who—during routine emergency care in the ICU—receive a focused ultrasound of the heart (a test called TEE). It helps doctors learn how this test is used and what outcomes follow, with no extra treatment required.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05004610RecruitingPhase 2
Hypertonic lactate treatment after cardiac arrest
This trial studies whether giving a specific IV fluid (hypertonic lactate) soon after resuscitation from cardiac arrest can improve recovery. It is for adults who remain in a deep unresponsive state after return of spontaneous circulation.
Brussels, BelgiumAges 18 years+ - NCT05132387Recruiting
Out-of-hospital cardiac arrest registry using automatic CPR
This study records information about people who suffer an out-of-hospital cardiac arrest and receive automatic chest compressions. It focuses on specific heart rhythms and emergency timing, which may help improve future emergency treatment.
WroclawAges 18–60 - NCT05139849RecruitingPhase 3
Testing vasopressin and steroids with adrenaline in cardiac arrest
This trial studies whether adding vasopressin and steroids to the standard emergency medicine adrenaline improves survival after out-of-hospital or in-hospital cardiac arrest. If you qualify, the treatment is chosen by chance (randomized) to help doctors learn which approach works best.
GothenburgAges 18 years+ - NCT05173740RecruitingPhase 4
Rehab program for people after an out-of-hospital cardiac arrest
This trial studies a rehabilitation program for adults who survived a first out-of-hospital cardiac arrest. It may help improve recovery after leaving the hospital by using guided follow-up and surveys to see how people are doing over time.
CopenhagenAges 18–65 - NCT05486884Recruiting
Blood pressure goal after out-of-hospital cardiac arrest
This study looks at whether targeting a specific blood pressure after a cardiac arrest can improve outcomes. It is mainly for people who are in intensive care and need a breathing machine because they are in a deep coma.
BrestAges 18 years+ - NCT05523999Recruiting
Recognizing out-of-hospital cardiac arrest in emergency calls
This study looks at how emergency dispatchers and communication systems can better recognize when a person may be in cardiac arrest during ambulance call handling. It may help EMS teams act faster, potentially improving outcomes.
PontoiseAges 18 years+ - NCT05606809Recruiting
Score brain injury after cardiac arrest ICU admission
This study compares different scoring methods to estimate early brain injury when people are admitted to the ICU after a cardiac arrest. It may help doctors choose the best early assessment approach for patients who are in a coma.
Nantes, Pays de LoireAges 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+ - NCT05917717Recruiting
Test a care bundle for adults after witnessed cardiac arrest
This trial studies a “care bundle” approach using special devices to improve care after an out-of-hospital or witnessed cardiac arrest. It may help by standardizing emergency treatment for people right after their heart stops.
Southampton, EnglandAges 18–120 - 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+ - 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 - NCT06229418Recruiting
Testing drone delivery of AEDs for rural cardiac arrests
This study is testing whether drones can deliver AEDs (devices that restart a stopped heart) more quickly to people having a cardiac arrest in rural areas. It looks at people whose heart stopped before emergency help arrived and who received a shock from a bystander's AED.
Clemmons, North CarolinaAges 18 years+ - NCT06466980Recruiting
Study of ventilator-related events after cardiac arrest
This study looks at lung-related problems that can happen when someone is on a breathing machine after surviving a cardiac arrest. If you qualify, researchers will track your recovery to better understand how to prevent these complications.
Corbeil-EssonnesAges 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+ - NCT06528704Recruiting
Real-time ventilation feedback during cardiac arrest
This trial tests if giving real-time feedback to rescuers during CPR can improve how they deliver breaths (rate and volume) to a person whose heart has stopped. It may help make ventilation more consistent and effective.
