Testing the LAMBRE device for left atrial appendage closure
This study is testing a device called LAMBRE that is used to close a small pocket in the heart (the left atrial appendage). The goal is to see how well it works in everyday medical practice for people who need this closure procedure.
PessacAges 18 years+ - NCT06275386Recruiting
Drug-coated balloon for chronic heart artery blockages
This trial tests whether a special balloon coated with medicine (drug-coated balloon) can safely open a completely blocked heart artery, instead of using a permanent stent. It may be an option for people who have chronic chest pain or shortness of breath due to a long-standing blockage.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT06262295Recruiting
Monitoring the safety of AVEIR leadless pacemakers
This study tracks the safety and performance of AVEIR VR LP and AVEIR AR LP leadless pacemakers in people who already have them or will get one. It helps doctors and researchers see how well these small heart devices work over time.
La TroncheAges 18 years+ - NCT06169241RecruitingEarly Phase 1
Nitrate supplement for resistant hypertension
This trial tests whether a natural nitrate supplement (like beetroot juice) can help lower blood pressure and improve blood vessel function in people with resistant hypertension. If you have resistant hypertension and your medications have been stable for at least 30 days, you may be eligible.
Rio de JaneiroAges 18–75 - NCT05987410Recruiting
Nordic walking for weight and heart health after a cardiac event
This trial tests if a nordic walking program helps people with diabetes who are overweight or obese recover after a heart attack or heart procedure. If you had a heart event or stent/bypass in the last 3 months, this program could help you get stronger and manage your weight.
MilanAges 18 years+ - NCT05903001Recruiting
Breathing muscle testing to help track lung disease
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT05800821Recruiting
Predicting brain blood-flow problems after carotid surgery
This study uses deep learning to predict which people are at risk for “cerebral hyperperfusion syndrome” (a dangerous spike in brain blood flow) after carotid revascularization. If you qualify, they’ll use scans/tests to estimate your risk so doctors can watch you more closely if needed.
MinskAges 30–80 - NCT05729009Recruiting
Testing blood-vessel function changes after heart transplant
This study looks at how tiny blood vessels in the body work over time in people who have had a heart transplant. It aims to better understand changes in blood flow and how these may relate to health after transplant.

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.
