Recruiting studies
- NCT06652087Recruiting
Testing rifaximin for heart failure with preserved pumping
This trial tests whether the antibiotic rifaximin (taken by mouth) can improve heart function in people with a type of heart failure where the heart pumps well but is still weak (HFpEF). Rifaximin might help by changing the bacteria in your gut.

Heart imaging study for a new ATTR-CM treatment
This trial uses heart scans to see how the drug acoramidis affects heart structure and function in people with a specific type of heart disease called ATTR cardiomyopathy. It may help doctors understand if the treatment is working.
St Louis, MissouriAges 18–80 - NCT04464655Recruiting
10-minute heart MRI protocol for people with heart conditions
This study uses a short, 10-minute heart MRI to check how well it works for people who need a clinically indicated heart scan. It may help streamline heart MRI testing, making exams faster while still providing useful heart information.
Montreal, QuebecAges 18 years+ - NCT07695363Recruiting
Restrictive fluids in liver transplant
This trial tests if giving less fluid during liver transplant surgery helps recovery. It is for adults with end-stage liver disease receiving a transplant.
Vancouver, British ColumbiaAges 18 years+ - NCT05574153Recruiting
Testing heart oxygen reserve in metabolic syndrome and healthy adults
This study measures how much oxygen your heart can use during stress and at rest using an MRI scan. It compares people with metabolic syndrome (a cluster of health risks) to people without those risks, to understand differences in heart function.
Montreal, QuebecAges 18–80 - NCT06262828Recruiting
Heart health study for Chinese with past CVD event
This study looks at heart health in Chinese patients who have had a past cardiovascular event. If you qualify, you'll help researchers learn more about heart disease and how to improve care.
Hong KongAges 18–80 - NCT04493970Recruiting
Study tests a CPR training app for high school students
This trial looks at whether using a required CPR training approach (through instruction and an app) improves learning among high school students. You may be asked to complete a short survey to help researchers understand how well the training is working.
Overland Park, KansasAges 12–25 - NCT07685106Recruiting
Cardiostory device test for heart failure in shortness of breath
This trial tests if a device called Cardiostory can tell if your shortness of breath (dyspnea) is caused by heart failure or something else. It's for people who started having trouble breathing in the last week.
Monastir, Monastir GovernorateAges 18 years+ - NCT06667258Recruiting
Earpiece to detect heart rhythm problems
This trial tests if a special earpiece can detect heart rhythm problems like irregular heartbeats. It could help you monitor your heart in a simple way.
London, Non-US/Non-CanadianAges 18 years+ - NCT07677319Recruiting
Heart surgery after age 75: a study on recovery
This study looks at how well people aged 75 and older recover after emergency heart surgery. It uses a special test to measure frailty and quality of life for one year after surgery.
Bordeaux, FranceAges 75 years+ - NCT07673536Recruiting
Heart transplant monitoring with extracellular vesicles
This study uses tiny particles called extracellular vesicles (which cells release) to check for signs of organ rejection after a heart transplant, aiming for a safer and less invasive alternative to biopsies.
Berlin, State of BerlinAges 18 years+ - NCT07678606Recruiting
4D MRI in chronic heart disease study
This study looks at whether a special 4D MRI scan can help doctors understand and predict the course of major chronic diseases. Participants will receive an extra scan during their regular cardiac MRI at Ulsan University Hospital.
Ulsan, UlsanAges 19 years+ - NCT06178510Recruiting
Breathing support after heart surgery
This trial tests a new way to help patients breathe after heart surgery. It compares standard breathing support with a new device that might help you recover faster in the ICU.
Vienna, State of ViennaAges 18–120 - NCT07667452Recruiting
AI patch study for heart failure recognition
This trial tests a new AI computer model that uses a single feature from a wearable patch to help recognize heart failure more easily. If you have heart failure with moderate to severe symptoms, this study may help improve how we monitor your condition.
Hangzhou, ZhejiangAges 18 years+ - NCT07669493Recruiting
Heart safety during chest radiation for cancer patients
This study looks at how chest radiation affects heart function and the immune system, and whether it is safe in people with lung, esophageal, breast, or thymus cancer who have not had chest radiation before.
Shijiazhuang, HebeiAges 18 years+ - NCT07669012RecruitingPhase 1
Sedation comparison for child heart hole repair
This study compares two sedation combinations (ketamine-propofol vs. dexmedetomidine-propofol) in children having a heart catheter procedure to close a simple hole or opening. The goal is to see which combination provides safer, more comfortable sedation.
CairoAges 2–12 - NCT07666451Recruiting
Heart and neck artery ultrasound study in healthy children
This study uses ultrasound (sound waves) to take pictures of the heart and the main neck arteries in healthy children across Italy. It helps doctors learn what normal measurements look like for different ages.
Bologna, BolognaAges birth–18 years - NCT07664189Enrolling by invitation
Left bundle pacing plus CRT vs. LBBP alone
This trial tests a new pacing approach that combines a left bundle branch pacemaker with standard cardiac resynchronization therapy (CRT) for people with heart failure. It aims to improve the heart's pumping efficiency compared to using the left bundle branch pacemaker alone.
Medellín, AntioquiaAges 18 years+ - NCT07666698RecruitingPhase 1/Phase 2
Metformin to improve heart function after LVAD implant
This trial tests if metformin, a medicine commonly used for diabetes, can help improve heart function in people who have a mechanical heart pump (LVAD). You may be able to join if you are between 18 and 75, have a continuous-flow LVAD, and have a condition called insulin resistance (where your body doesn't use insulin well) but your blood sugar levels are well-controlled.
Nanjing, JiangsuAges 18–75 - NCT06519747Recruiting
Detecting irregular heartbeat after non-heart surgery
This trial uses a monitoring device to check for a common but often overlooked irregular heartbeat (atrial fibrillation) after non-cardiac surgery. The goal is to detect and treat it early to prevent complications like stroke.
Hamilton, OntarioAges 18–120 - NCT07661940RecruitingPhase 2
SP16 for kidney protection during heart surgery
This trial tests a drug called SP16 to see if it can prevent acute kidney injury in people with chronic kidney disease who are having elective heart surgery with a heart-lung machine. It aims to help preserve kidney function after surgery.
Erlangen, BavariaAges 18 years+ - NCT06680986Recruiting
AI heart ultrasound study for high blood pressure
This trial uses artificial intelligence to analyze heart ultrasound images from people who had high blood pressure evaluations during a hospital stay. It aims to better understand how high blood pressure affects the heart.
Pierre-BéniteAges 18 years+ - NCT07649330Recruiting

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,288 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.
