Recruiting studies
- NCT06324682Recruiting
Comparing heart pacemaker types for better treatment
This trial looks at different ways to pace the heart (like left, right, or both sides) to see which works best for people who need a pacemaker. If you have a heart condition requiring a pacemaker, this study may help find the safest and most effective option for you.
Ferrara, FEAges 18 years+ - NCT06896773Enrolling by invitation

AI analyzes your ECG to help in high-risk heart rhythm cases
This trial uses an AI program to review ECG heart-tracing data collected from short-term monitoring devices. It aims to see whether the AI can better detect concerning heart rhythm patterns in people who are high risk for heart rhythm or heart problems.
Groningen, Provincie GroningenAges 4 years+ - NCT06804499Recruiting
Coronary artery disease and sudden cardiac arrest study
This study is for people with coronary artery disease (blocked arteries in the heart) who live in the Pirkanmaa area of Finland. It will collect information and blood samples to better understand heart disease and sudden cardiac arrest.
Tampere, PirkanmaaAges 18 years+ - NCT07143357Recruiting
Mind-body recovery program for cardiac arrest survivors and their caregivers
This trial tests a mind-body program to help cardiac arrest survivors and their caregivers recover together after a cardiac arrest. It combines in-person and video sessions to reduce emotional distress and improve wellbeing.
Boston, MassachusettsAges 18 years+ - NCT06918301Recruiting
Comparing heart measurements in cardiac surgery patients
This trial compares three ways to measure how well your heart pumps blood after cardiac surgery. It uses a standard catheter and two newer monitors to see which is most accurate.
KarlsburgAges 18 years+ - NCT07518524Recruiting
Fast Recovery After Heart Valve Surgery
This trial compares two recovery approaches after heart valve surgery: one that wakes you up very quickly in the operating room, and one that's slightly less aggressive. Both use techniques that avoid large chest incisions. The goal is to see which approach gets you breathing on your own sooner and helps you recover faster.
Legnano, ItalyAges 18 years+ - NCT03049254Recruiting
Registry and blood/tissue study for certain sudden heart death causes
This study builds a registry and collection of samples to better understand families affected by sudden heart death and related heart rhythm problems that are not clearly caused by a heart attack. It may help researchers identify patterns and improve future care, and it offers a way for patients and families to contribute to research.
Rochester, MinnesotaAges Any age - NCT03586518Recruiting
Non-contrast heart MRI test in dialysis patients
This trial checks whether a new kind of heart MRI (done without contrast dye) can help doctors see heart changes in people receiving hemodialysis. It may help improve how heart health is measured in dialysis care, especially for people with limited time.
Leicester, LeicestershireAges 18 years+ - NCT04064177Recruiting
Noninvasive heart monitoring for newborns
This study tests a noninvasive way to continuously measure heart output (how well the heart is pumping) in newborn babies. It may help clinicians monitor babies more safely and adjust care sooner.
LondonAges 1 hour–9 months - 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 - NCT05288894Recruiting
Italian registry for people with repaired Tetralogy of Fallot
This trial is a registry that collects information about people who have had Tetralogy of Fallot (TOF) repaired. It may help doctors better understand long-term outcomes and improve future care.
Ancona, The MarchesAges 10 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 - NCT06409585Recruiting
Heart muscle disease imaging study for scarring
This study uses advanced imaging (PET/MR or PET/CT) to look at scarring (fibrosis) in the heart muscle. It is for people with various heart muscle diseases, including heart failure with preserved pumping, thickened heart muscle, high blood pressure-related heart damage, heart inflammation, and others.
Edinburgh, ScotlandAges 30–90 - NCT06424119Recruiting
Intensive vs traditional cardiac rehab study
This study compares two types of cardiac rehab programs—Intensive Cardiac Rehabilitation and traditional rehab—to see which helps reduce inflammation and improve health. If you've had a recent heart event or have stable heart failure, this trial might be a good fit.
Ypsilanti, MichiganAges 18 years+ - NCT06585228Recruiting
Heart CT vs ultrasound to find clots after stroke
This study compares two ways to look for blood clots in the heart after a stroke: a heart CT scan and an ultrasound done through the food pipe. It aims to see if the CT scan can spot clots just as well as the more invasive ultrasound.
Amsterdam, North HollandAges 18 years+ - NCT06279793RecruitingPhase 2
Fish oil for recovery after high-risk heart surgery
This trial tests if giving fish oil through a vein before and after heart surgery can help patients recover faster. It is for people who have a high risk of complications during surgery.
AugsburgAges 18 years+ - NCT06754709Recruiting
Protein Changes in Children Having Heart Surgery
This study looks at a specific protein change in blood and heart tissue of children having heart surgery with a heart-lung machine. The goal is to understand how this protein might affect recovery.
NantesAges Up to 17 years - NCT06786416Recruiting
Monitoring to prevent kidney injury after heart surgery
This trial is testing a new monitoring system that tracks blood flow and other vital signs during heart surgery to help prevent kidney damage afterward.
San Donato Milanese, MilanoAges 18 years+ - NCT06813443Recruiting
Studying cardiomyopathy to find who needs a heart transplant
This study is looking at people with cardiomyopathy to understand which patients are most in need of a heart transplant. By joining, you will help doctors learn more about critical cases and improve care for heart muscle disease.
Bologna, Emilia-Romagna/BolognaAges 12 years+ - NCT06886789Recruiting
Staying healthy after cardiac rehab
This study tests a program to help people who have finished cardiac rehab keep up their healthy habits. The program uses a smartphone app and check-in calls to support your progress.
Providence, Rhode IslandAges 18 years+ - 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+ - NCT07388342Recruiting
CT heart scan after cardiac arrest without heart attack
This trial tests whether a special CT scan of the heart can help doctors see blockages in people who survived a cardiac arrest but did not have a typical heart attack. If you qualify, the CT scan might provide important information without needing a standard heart catheterization first.
Brussels, Vlaams BrabantAges 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.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,309 recruiting cardiac studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cardiac trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cardiac trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
