Vitamin D3 for Heart Health in Parkinson's Men
This study tests whether taking vitamin D3 supplements can improve the nerve function that controls your heartbeat in men with Parkinson's disease who have low vitamin D levels. If you have mild to moderate Parkinson's and are on levodopa, this trial may help understand if vitamin D can support your heart health.
Dhaka, ShahbagAges 51–70 - NCT07033676Enrolling by invitation
Study of a blood marker for heart damage from high blood pressure
This trial looks at a substance in your blood called miR-455-5p to see if it can help doctors understand heart changes caused by high blood pressure. It involves people who have had high blood pressure for over a year and may have some heart symptoms.
Shenzhen, GuangdongAges 18 years+ - NCT06693674RecruitingPhase 3
Sacubitril-valsartan for heart health in congenital heart disease
This trial tests if a drug called sacubitril-valsartan can improve heart structure and function in adults with congenital heart disease. You will take the drug and have heart imaging to see changes.
Rochester, MinnesotaAges 18 years+ - NCT07286227Recruiting
Checking heart function before removing support tubes in heart surgery
This study compares two methods—visual checks and a special ultrasound of the heart—to see which better predicts how well the heart will pump after bypass machine support is removed during elective heart surgery.
ErzurumAges 18–75 - NCT06353334RecruitingPhase 4
Butylphthalide for brain recovery after cardiac arrest
This trial tests if butylphthalide can improve brain function in people who have been resuscitated after a cardiac arrest. It may help reduce brain damage and improve recovery.
Beijing, Beijing MunicipalityAges 18–80 - NCT04890821Recruiting
Percutaneous ring repair for leaking tricuspid valve

Common questions
- Are there clinical trials for cardiac function?
- Yes. Clin2 currently lists 100 recruiting cardiac function 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 function 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 function 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.
