Tampere, PirkanmaaAges 18 years+ - NCT07009652Recruiting
Optimizing mobile ECMO for sudden cardiac arrest patients
This trial tests a better way to get a mobile team that can start ECMO (a heart-lung machine) to people who have a sudden cardiac arrest outside the hospital. The goal is to see if this approach can help save more lives in certain regions.
Ostrava, Moravian-Silesian RegionAges 3–60 - NCT07028372Recruiting
Long-term follow-up of cardiac arrest survivors who had ultra-rapid cooling
This trial checks on the long-term health of people who survived a cardiac arrest and received ultra-rapid cooling as part of an earlier study (OverCool). The goal is to see how they are doing over time.
AngersAges 18 years+ - NCT07174986RecruitingPhase 2/Phase 3
Double defibrillation for out-of-hospital cardiac arrest
This trial tests whether giving two shocks in a row (instead of one) helps restart the heart in people who have a cardiac arrest outside the hospital and need a defibrillator.
AmsterdamAges 18 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 - 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+ - NCT07444931Recruiting
Predicting cardiac arrest risk in heart disease patients
This study looks at factors that may help predict sudden cardiac arrest in people with coronary artery disease. If you have a recent diagnosis of significant blockage or a heart attack, joining this trial could help improve risk assessment.
HaderaAges 18–75 - 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 - NCT04189822Enrolling by invitation
Heart rhythm genetic registry and blood sample bio bank
This study is building a Canadian database and tissue/blood bank for people and families with inherited heart rhythm conditions (and some inherited heart muscle diseases). It collects consented health and genetic information to help researchers better understand who is at risk and how these conditions work.
Vancouver, British ColumbiaAges Any age - NCT07034170Enrolling by invitation
Muscle mass and recovery after cardiac arrest
This study looks at how muscle mass affects recovery after a cardiac arrest (when the heart stops). It is for people who stay on a breathing machine in the ICU for more than three days. Researchers will measure muscle to see if it helps predict recovery.
TaipeiAges 18–99 - 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+ - NCT06856993Recruiting
Study of early risk signs after sudden death
This study looks at tiny particles in the blood (exosomes) to see if they can help predict how patients do after a sudden collapse. The goal is to better understand who might recover and how to improve their care.
