This trial tests a new device that measures heart function without needing an invasive catheter. It aims to see if the device works as well as the standard right heart catheterization procedure.
Huntsville, AlabamaAges 18 years+ - NCT07286890Recruiting
Beating Heart Bypass Surgery Study with Getinge Devices
This study follows patients who have a type of heart bypass surgery called 'beating heart' CABG, where a special Getinge device is used to keep the heart pumping during the operation. It helps doctors learn more about how well these devices work in real-world use.
Stockton, CaliforniaAges 22 years+ - NCT04286516Recruiting

This study tests whether brain stimulation and robotic/arm training can improve arm movement in people who had a stroke. It may help strengthen movement and coordination by targeting brain pathways related to arm control.
Pittsburgh, PennsylvaniaAges 45–90 - NCT06303869Recruiting
Deep brain stimulation for speech after stroke
This study tests if deep brain stimulation (a small device implanted in the brain) can improve speech and arm movement after a stroke that affected the deeper parts of the brain. It is designed for people who have trouble speaking clearly (dysarthria) from their stroke.
Pittsburgh, PennsylvaniaAges 18–75 - NCT06601582Recruiting
Blood recovery during heart surgery study
This trial tests if a machine that collects and reuses blood during heart surgery can help patients avoid needing donor blood transfusions. It is for people having a first-time coronary bypass or heart valve surgery.
Recife, PernambucoAges 18 years+ - NCT06038838Recruiting
Tioga TMVR system feasibility study for mitral regurgitation
This trial tests a new device called the Tioga TMVR system to treat moderate to severe mitral regurgitation (leaky heart valve). It is for people who cannot have standard surgery or other less invasive treatments.
São PauloAges 18 years+ - NCT05725499Recruiting
Check if skin stimulation lowers blood pressure drops after spinal injury
This study tests a skin “stimulation” treatment to see if it helps stabilize blood pressure in people with spinal cord injury who get low blood pressure when sitting up. If you often have dizziness, faintness, or low readings after changing positions, this trial may help find safer ways to manage it.
West Orange, New JerseyAges 18–75 - NCT06195267Recruiting
Sivelestat for lung protection during emergency aortic surgery
This study tests whether a drug called sivelestat can protect your lungs and other organs during emergency surgery for a very serious aortic tear. If you qualify, you would receive the drug or a placebo right before and after surgery.
BeijingAges 18–90 - NCT07321899Recruiting
Study of a new tricuspid valve replacement device for severe leakage
This trial tests a new device called the Medtronic Intrepid TTVR system to replace the tricuspid valve in people with severe tricuspid regurgitation (leaky valve). It aims to see if the device can safely and effectively fix the leak and improve symptoms.
Phoenix, ArizonaAges 18 years+ - NCT05334888Recruiting
Study how sex and gut bacteria relate to heart risk
This study follows people over time to understand how sex-related factors and gut bacteria may affect heart and blood-vessel risk. It may help researchers identify who could benefit from earlier prevention, based on personal risk patterns.
BerlinAges 18–50 - NCT06572943Recruiting
Moderate exercise during pregnancy and heart health
This study looks at whether doing moderate exercise during pregnancy is safe and helpful for both mom and baby's heart health. If you are in your first trimester and do not have any high-risk conditions, you might be able to join.
IoanninaAges 18 years+ - NCT06480955Recruiting
Freezing bone tumors to cure them: a registry study
This trial is studying the use of a freezing treatment called cryoablation to completely destroy bone tumors that have spread from other cancers. It is for people who have only a few tumors or whose tumors are mostly stable, and who are healthy enough to undergo the procedure.
BordeauxAges 18 years+ - NCT04838249Recruiting
Hormone therapy study on eating, energy, and heart health
This study looks at how cross-sex hormone therapy affects appetite (eating behavior), metabolism (how your body uses food), energy balance, and cardiovascular (heart and blood vessel) health. You may be included if you meet specific health and safety requirements and can follow study procedures.
Leipzig, SaxonyAges 18 years+ - NCT06311149Recruiting
Study of LATITUDE heart device monitoring
This trial looks at how well the LATITUDE monitoring system works for people with heart devices. It checks if remote monitoring helps doctors track how your device is doing, so they can spot problems early.
FerraraAges Any age - NCT07061093Recruiting
Hormonal birth control and 24-hour blood pressure study
This study looks at how different types of hormonal birth control might affect your blood pressure over 24 hours. It could help you and your doctor choose a birth control that is safer for your heart.
Genova, GEAges 18–50 - NCT01143454Recruiting
Study unusual heart conditions and related genetic traits
This study looks at people with unusual or rare heart problems, or people with a family history of these issues. Doctors and researchers may collect and study your blood or tissue (and possibly store samples) to learn what causes the condition and how it may affect the heart.

Treating Heavily Calcified Heart Blockages to Improve Microcirculation
This study is testing a technique to treat heavily calcified (hard) blockages in heart arteries. The goal is to see if a special way of preparing the blockage before placing a stent helps improve blood flow to the tiny blood vessels in the heart muscle.
KatowiceAges 18 years+ - NCT06272734Recruiting
Reprieve system study for hospitalized heart failure
This study tests a device (Reprieve System) to remove extra fluid more safely in heart failure patients while they are hospitalized. It may be a good option if you have fluid buildup and are not too sick from other conditions.
TbilisiAges 18 years+ - NCT05496998Recruiting
Heart valve replacement using a catheter for leaking mitral valve
This trial studies a catheter-based procedure to replace the mitral valve in people with severe (or specific moderate) mitral valve leakage that causes symptoms. It may help by reducing leaking and related symptoms when standard surgery or less invasive fixes aren’t suitable for you.

Common questions
- Are there clinical trials for cardiovascular system?
- Yes. Clin2 currently lists 99 recruiting cardiovascular system 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 cardiovascular system 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 cardiovascular system 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.
