Recruiting studies
- NCT07444398RecruitingPhase 1

Heart function and fatigue in Friedreich's ataxia
This study looks at how the heart works during exercise and how that relates to fatigue in people with Friedreich's ataxia. You'll ride a stationary bike, and we'll measure your heart's output to understand fatigue better.
New York, New YorkAges Any age - NCT06115759Recruiting
Recovery and activity study after open-heart surgery
This study tests a new recovery plan called T-REX to see if it helps patients feel better and get back to moving sooner after open-heart surgery. It is for people having surgery at Thorax Centrum Twente.
Enschede, OverijsselAges 18 years+ - NCT07434193Recruiting
Pacing study after aortic valve replacement
This trial tests if special pacing of the heart's lower chambers (called cardiac resynchronization therapy, or CRT) can help people who develop a new electrical delay in the heart after having a transcatheter aortic valve replacement (TAVI). The study compares two types of pacing to see which works better for recovery.
BudapestAges 18 years+ - NCT07430007Recruiting
Exercise and diet to reduce AFib burden
This study tests whether a program of exercise and healthy eating changes can reduce how often atrial fibrillation (AFib) happens and help you lose weight. It may be a good fit if you are overweight, have AFib, and are ready to make lifestyle changes.
Jyväskylä, Central FinlandAges 18–75 - NCT07431710Recruiting
AI-guided chest compressions for cardiac arrest in the ER
This trial tests whether artificial intelligence (AI) can help doctors give better chest compressions during CPR for adults whose hearts stopped outside the hospital. The goal is to improve blood flow and outcomes without using special equipment in the ambulance.
New Taipei City, BanqiaoAges 20 years+ - NCT07430553Recruiting
Comparing pacemakers for better heart function in heart failure
This trial compares three types of advanced pacemakers (cardiac resynchronization therapy devices) to see which works best for improving heart function and reducing abnormal heart rhythms in people with heart failure.
London, Greater LondonAges 18 years+ - NCT07430813Recruiting
Drone delivery of defibrillators for bystanders
This study tests if drones can deliver a defibrillator to people who witness a cardiac arrest, helping them provide lifesaving care before an ambulance arrives. You may be asked to use a training manikin to see how quickly you can help.
Guildford, SurreyAges 18 years+ - NCT06258681Recruiting
Breathing exercise device for recovery after heart surgery
This trial tests a new breathing exercise device designed to help your lungs recover after heart surgery. It may make your breathing easier and speed up your return to daily activities.
Istanbul, IstanbulAges 40–65 - NCT06778811RecruitingPhase 4
Sleep quality study for heart surgery patients
This trial studies sleep problems before and after heart surgery. It tests two medicines to see if they can help improve sleep. This may help you recover better after surgery.
Nanjing, JiangsuAges 40–75 - NCT05359263RecruitingPhase 2
Dapagliflozin for kidney disease to improve heart structure
This Phase 2 study tests whether dapagliflozin can improve heart structure and function in people with chronic kidney disease (CKD). Dapagliflozin is a kidney-heart medicine that may affect how the heart changes over time, measured by heart scans.
CopenhagenAges 18 years+ - NCT07420400Recruiting
Detecting heart shunts without needles
This trial uses a specialized ultrasound test (TEE with bubble study) to find a small opening in the heart called a PFO. It may help people who need this test to check for causes of certain health problems.
La Jolla, CaliforniaAges 18 years+ - NCT07424625RecruitingPhase 4
Comparing two medicines for acidosis after heart surgery
This trial compares two medicines, THAM and sodium bicarbonate, to treat metabolic acidosis (too much acid in the blood) after heart surgery that used a heart-lung machine. The goal is to see which medicine works better for patients in this situation.
Rochester, MinnesotaAges 21 years+ - NCT07422129Recruiting
Aortic wall analysis during heart surgery
This study looks at the structure and strength of the aorta (the main artery from your heart) in patients having surgery to replace part of it or having a heart transplant. The goal is to better understand the aortic wall to improve future treatments.
Pavia, LombardyAges 18 years+ - NCT06812455RecruitingPhase 4
Rivaroxaban for blood clot after heart catheterization
This trial tests if a blood thinner called Rivaroxaban can treat a blood clot that forms in the wrist artery after a heart catheterization. If you have this clot, taking Rivaroxaban may help reopen the artery and improve blood flow.
ThessalonikiAges 18 years+ - NCT01728597Recruiting
Cardiac MRI scan without contrast for normal imaging values
This study measures normal heart images using an MRI scan without contrast dye. It’s meant to improve and standardize how doctors collect heart images for future patients.
Graz, StyriaAges 18–80 - NCT07414251Recruiting
Preparing children for heart procedures
This study looks at how children prepare for heart surgery or a heart catheterization. It will ask families to fill out questionnaires to help improve preoperative care.
Berlin, State of BerlinAges Up to 18 years - NCT07410988RecruitingPhase 4
Starch vs. crystalloid fluid for heart surgery patients
This trial compares two types of IV fluids (a starch solution vs. a balanced salt solution) to see which one better protects kidneys after heart surgery. It is for adults having planned heart surgery who do not have severe kidney problems.
DaejeonAges 19 years+ - NCT07410481Recruiting
Therapy for PTSD after a cardiac arrest
This study compares two talking therapies for PTSD after a cardiac arrest. One combines mindfulness and acceptance with gradual exposure to difficult memories; the other focuses on present life challenges. Both aim to reduce distress and improve quality of life.
New York, New YorkAges 18–81 - NCT05166954Recruiting
Bariatric surgery and heart function in people with high blood pressure
This study looks at whether bariatric (weight-loss) surgery improves heart function in people who have high blood pressure. You may be able to join if you’re already a bariatric surgery patient at the study hospital and meet the health and medication criteria.
Beijing, Beijing MunicipalityAges 17–70 - NCT05498675Recruiting
Sacubitril/valsartan study for high blood pressure by body size
This study tests how sacubitril/valsartan may affect heart function in people with high blood pressure, and whether results differ by body size (BMI). You may benefit by getting closer heart monitoring, though it depends on whether you fit the safety and medical criteria.
Beijing, Beijing MunicipalityAges 18–70 - NCT07401836Recruiting
Sleep bundle for heart surgery patients
This trial tests a special sleep program (bundle) to help patients sleep better after heart surgery. Researchers want to see if it improves recovery and well-being.
Saint John, New BrunswickAges 19 years+ - NCT07400406Recruiting

This trial tests a special MRI using a contrast agent called ferumoxytol to better see calcium buildup in heart arteries. It may help people who need a coronary angiogram and have some calcium visible on a prior CT scan.
Nanjing, JiangsuAges 18–75 - NCT07405229RecruitingPhase 4
Medical treatment for idiopathic ventricular fibrillation patients
This study tests medical treatments for people who survived a cardiac arrest with a specific heart rhythm problem called idiopathic ventricular fibrillation. If your cardiac arrest was likely from a heart issue but not from clogged arteries, you might help find better treatments.

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.
