Heart ultrasound study in multiple myeloma treated with RVd
This study looks at how a new heart ultrasound test can measure heart side effects and overall outcomes in people with multiple myeloma who are treated with the RVd drug combination. It may help doctors better understand heart risks during treatment.
Jinan, ShandongAges 18–70 - NCT01670383Recruiting
Study sample collection for sepsis and after cardiac arrest
This trial collects and stores small samples from people in the ICU who are either being treated for sepsis or who have survived a non-traumatic cardiac arrest. It may help researchers better understand how the body changes after severe infection or after revival, which could improve future care.
SeoulAges 16 years+ - NCT07867197Recruiting
Digital cardiac rehab for heart attack survivors
This trial tests a digital cardiac rehabilitation program delivered via smartphone for people who've had a heart attack. It aims to help improve your daily function and recovery from the comfort of your home.
Minya, Minya ProvinceAges 55–65 - NCT03111173Recruiting
Check if a standard ECG can record your baby’s heart activity
This study tests whether a routine heart recording test (ECG) can capture fetal (baby) heart activity during late pregnancy. It may help researchers find simpler ways to monitor baby heart rhythm without special equipment.
Seattle, WashingtonAges 18–55 - NCT06214195RecruitingPhase 3
Shengmai San to prevent heart damage from breast cancer therapy
This trial tests if a traditional Chinese medicine called Shengmai San can protect the heart during chemotherapy and targeted therapy for HER2-positive breast cancer. Patients take the supplement alongside standard treatment to see if it reduces the risk of heart problems.
Hangzhou, ZhejiangAges 18 years+ - NCT06172842Recruiting
Heart ultrasound study for electrical rhythm problems
This study uses special ultrasound techniques to look at how the heart works in people who have heart rhythm problems caused by electrical issues, not structural ones. It aims to better understand and treat these conditions.
GuangzhouAges Any age - NCT07857811Recruiting
Blood pressure monitoring in young children during heart surgery
This study looks at how blood pressure readings from the arm compare to readings from the aorta during heart surgery with a heart-lung machine in children up to 3 years old. It aims to improve blood pressure monitoring during and after surgery.
Santiago, Santiago MetropolitanAges birth–3 years - NCT07871188Recruiting
Blood pressure swings and recovery after heart bypass surgery
This study looks at how changes in blood pressure during heart bypass surgery relate to how quickly the body clears lactic acid afterwards, which is a sign of recovery. It may help doctors understand recovery patterns after surgery.
GaziantepAges 18–80 - NCT03197350Recruiting
Study of heart failure with preserved pumping function
This study looks at people who have heart failure symptoms but whose heart pumping strength is not reduced. Researchers aim to better understand this type of heart failure and compare it with people who have no history of heart disease or heart failure.
BrusselsAges 18–99 - NCT02884271Recruiting
Study CPR during surgery when the heart stops
This trial looks at cardiopulmonary resuscitation (CPR) provided right in the operating room when a patient’s heart stops. It may help improve how emergency care is delivered during surgery.
IzmirAges Any age - NCT05775588Recruiting
Lung valve treatment for severe COPD
This study tests tiny valves placed in your airways to see if they improve your heart and muscle function over the long term. It's for people with severe COPD (chronic lung disease) and significant emphysema damage.
Beijing, Beijing MunicipalityAges 18–90 - NCT05002543Recruiting
Real-world study of heart valve repair devices for multiple valves
This study checks how well and how safely CORCYM valve devices work in real-world patients with heart valve problems in the aortic, mitral, and/or tricuspid positions. It may help doctors understand expected outcomes outside of tightly controlled research settings.
Indianapolis, IndianaAges Any age - NCT06090591Recruiting
Heart condition research registry at Dubrava Hospital
This study is a registry that will collect information from people with certain heart conditions (like having a pacemaker, a blood clot, a heart attack, or a valve replacement procedure called TAVI). The goal is to learn more about these conditions and how they are treated.
ZagrebAges 18 years+ - NCT05706194Recruiting
Early brain prognosis test after out-of-hospital cardiac arrest
This trial studies how to predict brain recovery early after a non-traumatic out-of-hospital cardiac arrest. The goal is to help clinicians estimate outcome sooner, which may improve decision-making during intensive care.
HelsinkiAges 18–100 - NCT04158479Recruiting
Registry for people on ECMO life support
This registry collects information about people who are placed on ECMO, a heart-lung machine used to support breathing and/or circulation. It may help doctors better understand who benefits and how to manage ECMO in the future.

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.
