Recruiting studies
- NCT07611890RecruitingPhase 4
Comparing two medications to reduce heart stress during cardiac surgery

TomskAges 18 years+ - NCT05660798Recruiting
Switching from cigarettes to heat-not-burn to protect heart arteries
This study looks at whether switching from regular cigarettes to a tobacco heating product slows buildup of plaque in the heart arteries. You’d be guided through smoking change and monitored using heart scans, to see if artery plaque stays the same or improves.

Hypertension registry study in Morocco
This study is creating a registry of people with high blood pressure in Morocco. It aims to understand different types of hypertension, related health problems, and how to personalize treatment.
Meknes, MoroccoAges 18 years+ - NCT07462910Recruiting
Checking diaphragm nerve function after pulsed field ablation
This study looks at how a new type of catheter ablation (pulsed field ablation) for atrial fibrillation affects the phrenic nerve, which controls the diaphragm. Researchers will use X-rays to see if the treatment causes any temporary diaphragm problems.
MontrealAges 18 years+ - NCT07456085Enrolling by invitationPhase 3
Rivaroxaban vs warfarin for mechanical heart valves
This trial compares a newer blood thinner (rivaroxaban) to the standard one (warfarin) for people with mechanical heart valves who have had clots or bleeding while on warfarin, or who cannot easily monitor their INR levels. It aims to see if rivaroxaban is safer and more effective.
Rawalpindi, Punjab ProvinceAges 18 years+ - NCT06156670Recruiting
A study of closing a PFO to prevent strokes
This trial looks at the safety and results of closing a PFO (a small hole in the heart) in people who have had a stroke or embolism with no other clear cause. If you qualify, doctors will close your PFO using a small tube inserted through a blood vessel and then follow your health over time.
MoscowAges 18–70 - NCT07452991Recruiting
Ultrasound-guided clot-busting for moderate-risk pulmonary embolism
This trial tests a procedure that uses ultrasound to guide a catheter that delivers clot-dissolving medicine directly to a blood clot in the lungs. It is for people who have a pulmonary embolism that causes some heart strain but who are not in shock.
MoscowAges 18 years+ - NCT07435337RecruitingPhase 4
Pain medicine study for heart surgery patients
This trial tests two different pain medicines, nalbuphine and fentanyl, to see which one causes fewer changes in blood pressure and heart rate during the placement of a breathing tube for heart surgery.
Rawalpindi, Punjab ProvinceAges 40–60 - NCT07432828Recruiting
Sleep problems and heart disease: a study link
This study looks at how sleep issues (like trouble sleeping or feeling very sleepy during the day) might be related to heart conditions. If you see a heart doctor, you can help by filling out a simple questionnaire about your sleep.
Carquefou, FranceAges 18 years+ - NCT07424209Recruiting
Hypnotic communication during heart catheterization study
This study tests whether talking in a special relaxed way (hypnotic communication) during a heart procedure can help you feel calmer and more comfortable. You may be able to join if you are at least 18, can understand Italian, and are already scheduled for a coronary angiogram.
Ponderano, ItalyAges 18 years+ - NCT01777828Recruiting
Registry for patients with valve replacements via catheter

RennesAges Any age - NCT06826872RecruitingPhase 2
Testing SPC1001 for essential hypertension
This trial tests an oral medication called SPC1001 to see if it can safely lower blood pressure in people with essential hypertension (high blood pressure not caused by another condition). It may help if you have mild to moderate high blood pressure.
SeoulAges 19–75 - NCT07386028Recruiting
Large chest cut vs small chest cut for aorta repair
This trial compares two surgical approaches for repairing an enlarged ascending aorta: the standard large chest incision and a smaller incision through the breastbone. It aims to see if the smaller cut leads to faster recovery.
TomskAges 18–80 - NCT06839755Recruiting
Stress echo's positive value in heart health
This study looks at how well a stress echocardiogram (heart ultrasound during exercise or medication) predicts future health in people who have some sign of reduced blood flow to the heart. The goal is to confirm that a positive stress echo is a good sign for guiding next steps.
Athens, AtticaAges 18–100 - NCT07374913Recruiting
Study of COL4A1 and COL4A2 gene mutations
This study looks at people with a mutation in the COL4A1 or COL4A2 genes, which can cause problems in small blood vessels throughout the body. It aims to learn more about the condition and may also include family members who carry the mutation or who can serve as healthy controls.

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