All recruiting trials (10)

• Prehospital femoral arterial access to monitor blood pressure during OHCA

  This pilot study tests whether placing a femoral arterial sheath before hospital arrival is feasible and safe in adults with non-traumatic OHCA to enable invasive blood pressure monitoring and better vasopressor control.

  Recruiting Emergency Medical Service, Prague · Prague · NCT07596446

• Predicting sudden cardiac arrest risk in people with coronary artery disease

  This project will try to see if combining genetics, ECGs, blood biomarkers, imaging, and psychosocial information can predict which people with coronary artery disease are most likely to have sudden cardiac arrest.

  Recruiting at 3 sites Tampere Heart Hospital · Hadera and 2 other locations · NCT07444931

• Identifying risk factors for sudden cardiac arrest in coronary artery disease patients

  This study is trying to find out what clinical and genetic factors might increase the risk of sudden cardiac arrest in people with coronary artery disease.

  Recruiting Tampere Heart Hospital · Tampere, Pirkanmaa · NCT06804499

• Genetic assessment of young athletes who experience sudden cardiac arrest during sports

  This study looks at young athletes aged 12 to 35 who have had sudden cardiac arrest during sports to see if genetic factors played a role and to help prevent similar events in others.

  Recruiting at 15 sites Rennes University Hospital · Nîmes, France and 25 other locations · NCT06642168

• Drone-delivered AEDs for cardiac arrests in rural areas

  This project tests whether delivering AEDs by emergency drones to out-of-hospital cardiac arrest sites can reach patients faster than current first responders and EMS in rural communities.

  Recruiting Duke University · Clemmons, North Carolina · NCT06229418

• Evaluation of a wearable defibrillator for sudden cardiac arrest

  This study is testing how well a wearable defibrillator works for people at risk of sudden cardiac arrest by looking at real-life data from patients using the device.

  Recruiting Kestra Medical Technologies, Inc. · Seattle, Washington · NCT05135403

• Registry for HeartStart HS1 Defibrillator performance and safety

  This study looks at how well the HeartStart HS1 Defibrillator works and keeps people safe after they have a suspected heart attack.

  Recruiting Heartstream US LLC · Pittsburgh, Pennsylvania · NCT04840797

• Registry for the HeartStart FRx Defibrillator's performance in cardiac arrest cases

  This study is collecting information on how well the HeartStart FRx defibrillator works during cardiac arrests to see if it lives up to its promises.

  Recruiting Heartstream US LLC · Monroeville, Pennsylvania · NCT04250857

• Evaluating low versus standard doses of epinephrine for out-of-hospital cardiac arrest

  This study tests whether giving a lower dose of epinephrine can help adults who have a cardiac arrest outside of the hospital more effectively than the standard higher dose.

  Recruiting at 9 sites Phase 4 Unity Health Toronto · Victoria, British Columbia and 8 other locations · NCT03826524

• Registry and biobank for arrhythmogenic ventricular cardiomyopathy

  This study is trying to gather information and samples from people with arrhythmogenic ventricular cardiomyopathy and their families to better understand the genetic causes of the condition and improve early diagnosis for those at risk.

  Recruiting at 2 sites Mayo Clinic · Rochester, Minnesota and 1 other locations · NCT03049254

NIH-funded research (4)

Early-stage science funded by the US National Institutes of Health. Most of these projects don't enroll patients, but they show what is being worked on.

• Mitochondrial DNA differences linked to sudden cardiac arrest risk and recovery

  This research looks at whether differences in mitochondrial DNA affect a person's risk of sudden cardiac arrest and their chances of recovery after resuscitation.

  NIH research Johns Hopkins University · Baltimore, United States · NIH-11251647

• Investigating how mitochondrial genetics affect the risk of sudden cardiac arrest and resuscitation outcomes.

  This study is looking at how changes in mitochondrial DNA might affect the risk of sudden cardiac arrest and how well people respond to resuscitation, with the goal of finding new ways to help improve survival rates and create personalized treatments for patients.

  NIH research Johns Hopkins University · Baltimore, United States · NIH-11074680

• Using artificial intelligence to assess genetic risk for sudden cardiac arrest through ECG analysis

  This study is looking at how artificial intelligence can help doctors read heart tests (ECGs) to find out if someone has a genetic risk for sudden cardiac arrest, especially for people who might not have easy access to regular genetic testing.

  NIH research Icahn School of Medicine at Mount Sinai · New York, United States · NIH-10998172

• Investigating how second-generation antipsychotic medications may lead to sudden cardiac arrest.

  This study is looking at how certain antipsychotic medications might affect heart health in people with schizophrenia and other mental health conditions, so doctors can better understand which medication combinations are safe and help keep patients healthy.

  NIH research University of Pennsylvania · Philadelphia, United States · NIH-10842279

How many Sudden Cardiac Arrest clinical trials are recruiting right now?

10, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.

Where are these trials running?

In 9 countries. The most sites are in United States (5 trials), Canada (1 trial), Israel (1 trial), Moldova (1 trial), Romania (1 trial). Each study page lists its sites and which ones are recruiting.

What phases are they in?

Phase 4: 1. Trials with no phase listed are usually device, behavioural or observational studies.

How do I join one?

Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
