Recruiting studies
- NCT07002450Recruiting
CT scan to check for clots before heart shock therapy
This trial uses a CT scan of the left atrium to check for blood clots before a procedure called cardioversion (an electric shock to restore normal heart rhythm). The goal is to see if the CT scan can safely replace other imaging methods in the emergency department, helping to speed up treatment.
Hershey, PennsylvaniaAges 18 years+ - NCT06986967Recruiting
Comparing Blood Flow Methods During Aortic Arch Surgery
This study compares two methods of supplying blood to the brain during surgery on the main artery from the heart (aorta) and the aortic arch. It may help determine the safest way to protect the brain during cooling and surgery.
Durham, North CarolinaAges 18 years+ - NCT06985901Recruiting
Pulsed-field ablation for persistent atrial fibrillation
This trial tests a new type of ablation (pulsed-field) to treat persistent atrial fibrillation (AFib) that lasts more than 7 days. You may qualify if you have symptoms and haven't had other heart ablation procedures except for one specific type.
NiceAges 18 years+ - NCT05775484Recruiting
Exercise program to slow heart and blood vessel aging
This trial tests whether a structured exercise program can slow how quickly your cardiovascular system (heart and blood vessels) “ages” over time. If you’re able to move around outdoors safely, exercise may be a key part of the study.
Singapore, SingaporeAges 21–100 - NCT05946174Recruiting
Personalized frailty program for older people with heart frailty
This trial aims to adjust frailty-support activities for people who are physically vulnerable because of heart problems. It may help by creating a plan tailored to your needs, while carefully checking health issues that could make participation unsafe.
SingaporeAges 21–100 - NCT06128330RecruitingPhase 4
Bedside test for bleeding prevention drug in heart surgery
This study tests a quick bedside measurement of how well the drug tranexamic acid works to prevent bleeding during heart surgery. It may help doctors give the right dose to reduce blood loss.
BernAges 18–90 - NCT06405516Recruiting
Platelet function after heart surgery
This study watches how well platelets (cells that help blood clot) work in people who have high-risk heart surgery using a heart-lung machine for more than 2 hours. The goal is to learn more about bleeding risks after surgery.
BernAges 18 years+ - NCT06976502Enrolling by invitation
Health eHeart Biobank
This trial collects blood and tissue samples from people with and without heart disease to study heart health. If you are 18 or older and either a UCSF patient, a family member of a heart patient, or have no heart disease, you may be able to help.
San Francisco, CaliforniaAges 18 years+ - NCT06973902Recruiting
A study on heart pump therapy and stress echo for advanced heart failure
This trial tests how well a heart stress ultrasound (dobutamine echo) can predict if you will get better from a special heart device called cardiac contractility modulation (CCM). CCM is a pacemaker-like implant for people with advanced heart failure who still have symptoms even with the best medicines. The study will help doctors know which patients benefit the most from this device.
Marcianise, CampaniaAges 18 years+ - NCT05966675Recruiting
Special heart pacing after TAVI to help protect heart function
This trial looks at a physiologic (more natural) heart pacing approach to prevent weakening of the heart’s main pumping chamber after TAVI. It enrolls people who recently had TAVI and now meet standard reasons for needing a permanent pacemaker.
KatowiceAges 18 years+ - NCT06965504Recruiting
Heart failure medications with an Impella heart pump for cardiogenic shock
This study tests whether a special heart pump (Impella 5.5) can help patients with severe heart failure (cardiogenic shock) safely start and increase their heart failure medications. The goal is to see if this approach can help the heart recover and improve outcomes.
Tampa, FloridaAges 18–80 - NCT06968936Recruiting
Long-term outcomes of pre-surgery iron therapy
This study looks at long-term results of giving iron before major heart surgery to people with low iron levels. It aims to see if this treatment helps recovery and outcomes.
Hangzhou, ZhejiangAges 18–85 - NCT06964464RecruitingPhase 4
Comparing two heart failure medications in ICD patients
This trial compares two beta-blocker medications, carvedilol and metoprolol succinate, to see which one works better for people with heart failure who have an implantable cardioverter defibrillator (ICD). If you are currently taking metoprolol succinate, you may be able to switch to carvedilol and help researchers find the best treatment.
Scottsdale, ArizonaAges 18 years+ - NCT06969287RecruitingPhase 3
Testing fluvoxamine to prevent confusion after surgery
This trial tests if a medication called fluvoxamine can help prevent delirium (sudden confusion and disorientation) after non-cardiac surgery. If you are having surgery that requires at least a 2-day hospital stay, this study may be for you.
St Louis, MissouriAges 60 years+ - NCT06759389Recruiting
Ventor study for cardiac arrest outside the hospital
This trial is testing a new device or procedure for adults who have a cardiac arrest outside the hospital. It aims to see if it can help improve outcomes for patients like you.
Stony Brook, New YorkAges 18–75 - NCT06957548Enrolling by invitation
Heart and diabetes risk in Cameroon adults
This study looks at risk factors for heart disease and diabetes in adults living in or from Cameroon. It involves a simple screening to better understand your health.
Douala, Littoral RegionAges 18 years+ - NCT06956560Recruiting
Heart Scar Imaging Study for Heart Attack and Failure Patients
This study uses a special imaging agent to see a protein called PDGFRß in the heart, which may help detect scarring (fibrosis) after a heart attack or in heart failure. It aims to improve how we understand and treat heart muscle damage.
UppsalaAges 40–70 - NCT06961175Recruiting
Platelet function study in heart surgery
This study looks at how well platelets work during heart surgery using a special test called thromboelastography. It may help doctors understand and manage bleeding risks in people having planned heart surgery with a heart-lung machine.
SalamancaAges 18 years+ - NCT05588024Recruiting
Device-assisted CPR with head and chest elevation during arrest
This trial studies a CPR method that uses a device to help raise the head and chest during active resuscitation after cardiac arrest. It may help guide whether this technique improves outcomes for people who are not breathing normally and do not have a pulse.
Minneapolis, MinnesotaAges 18 years+ - NCT06952387Recruiting
Personalized blood pressure for high-risk surgery patients
This study tests whether personalized blood pressure management during and after major surgery can reduce complications and death in older adults with heart or blood vessel risks. It aims to find the safest blood pressure targets for each patient.
Guangzhou, GuangdongAges 65–90 - NCT06946290Recruiting
Nerve block for pain relief after heart surgery
This study tests a nerve block, called an intertransverse process block, to see if it helps people feel better and recover faster after heart surgery. The block is given during surgery to reduce pain.
Hong KongAges 18 years+ - NCT06951867Recruiting

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,291 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.
