Recruiting studies
- NCT07541222Recruiting
Blood pressure medications and surgery recovery outcomes
This study looks at how blood pressure medications affect low blood pressure episodes that happen during and after heart surgery. Researchers want to understand if the number of blood pressure drugs you take before surgery changes how your body handles blood pressure during the operation.
KonyaAges 40 years+ - NCT07532174Recruiting
Blood-Cleaning Device During Heart Surgery
This trial tests a special blood-filtering device (Efferon LPS) used during heart surgery to reduce inflammation and improve recovery. The device removes harmful substances from your blood during the operation.
BarnaulAges 18 years+ - NCT07531602Enrolling by invitation
How breathing pressure affects heart function during surgery
This study observes how different levels of breathing support during heart surgery affect your heart's function. Researchers will use ultrasound and monitoring tools already planned for your surgery to see how small changes in breathing pressure impact your heart's performance.
Boston, MassachusettsAges 18 years+ - NCT07511673Recruiting
Dental screening before heart valve surgery
This trial tests whether a dental checkup before heart valve surgery can improve recovery and prevent complications. If you are scheduled for a heart valve procedure, you may be able to join.
GothenburgAges 18 years+ - NCT07513974Recruiting
Pain sensitivity test to predict opioid needs in heart surgery
This study measures how sensitive you are to pain using a special device, then tracks how much pain medication you need during heart surgery. The goal is to see if pain sensitivity can predict opioid requirements and help doctors customize pain control for you.
Brussels, AnderlechtAges Any age - NCT07490184Recruiting
Heart check vs frailty score for hip surgery
This trial compares two ways to evaluate older adults before hip surgery to see which better predicts recovery. It may help doctors choose the safest approach for you.
Dallas, TexasAges 60 years+ - NCT07492979Recruiting
Pacemaker placement study for heart failure
This trial compares two types of pacemaker placement to improve heart function in people with heart failure. One method paces the heart's natural conduction system, while the other paces the lower chambers of the heart. The goal is to find which approach works better for heart resynchronization therapy.
AarhusAges 18–99 - NCT07496424Recruiting
Comparing manual vs automatic strain in heart surgery patients
This trial compares two ways of measuring heart strain (the heart's ability to squeeze) after cardiac surgery. It uses GE ultrasound machines and special software to see if automatic measurements are as good as manual ones.
ViennaAges 18–99 - NCT06632613RecruitingPhase 2
Trial of ENN0403 to prevent kidney injury after heart surgery
This study tests a new drug (ENN0403) given during heart surgery to see if it prevents acute kidney injury—a sudden drop in kidney function. The trial is for people who are already at higher risk due to their specific heart surgery and other health factors.
ShanghaiAges 18–85 - NCT06774326Recruiting
Spectral CT to check for heart damage from lymphoma treatment
This study uses a special type of CT scan called spectral CT to see if chemotherapy drugs called anthracyclines can cause heart damage in people with certain lymphomas. The goal is to catch any heart problems early by imaging the heart before, during, and after treatment.
BolognaAges 18 years+ - NCT06528704Recruiting
Real-time ventilation feedback during cardiac arrest
This trial tests if giving real-time feedback to rescuers during CPR can improve how they deliver breaths (rate and volume) to a person whose heart has stopped. It may help make ventilation more consistent and effective.
Knokke, West-VlaanderenAges 18 years+ - NCT07483151Recruiting
Heart Surgery and Thinking Changes Study
This study looks at how changes in blood flow (called venous congestion) after heart surgery might affect thinking and memory. It aims to find out if there is a link between how blood returns to the heart and brain function after surgery.
Yangzhou, JiangsuAges 18 years+ - NCT07483047Recruiting
Predicting memory changes after heart surgery in older adults
This study looks at older adults having heart surgery to find out who might have trouble thinking or remembering afterward. Researchers hope to build a tool to predict this risk so doctors can help sooner.
ShanghaiAges 65 years+ - NCT07481396Recruiting
Studying brain injury after cardiac arrest through spinal fluid
This trial is looking at the spinal fluid of people who survived a cardiac arrest outside the hospital and are being treated for brain injury. The goal is to learn more about brain damage and find new ways to help patients recover.
Daejeon, Jung-guAges 18 years+ - NCT07472296Recruiting
Comparing nerve blocks for heart surgery pain relief
This trial compares different types of nerve blocks to see which works best for managing pain after heart surgery through the breastbone. It may help reduce the need for strong pain medications.
Bursa, NilüferAges 18–80 - NCT07464938Recruiting
Predicting brain recovery after cardiac arrest
This study is testing new tools and markers to better predict recovery after cardiac arrest when brain injury may occur. It involves adults who had a cardiac arrest outside the hospital and are being treated at Saint-Luc hospital.
BrusselsAges 18 years+ - NCT03360838Recruiting
Prediction test for confusion after heart surgery in older adults
This study uses a short, self-answered thinking test before elective heart surgery to help predict who may develop confusion afterward. The goal is to improve early identification and care planning for patients at higher risk.
BaselAges 60 years+ - NCT07456722Recruiting
Heart health in spinal cord injury with autonomic dysreflexia
This study looks at how the heart is built and works in people with long-term spinal cord injury, especially those who have autonomic dysreflexia. It might help doctors understand heart risks and improve care.
NottwilAges 18 years+ - NCT06386094Recruiting
Fatty Liver Disease and Heart Function Study
This study checks how fatty liver disease (a condition where fat builds up in the liver) affects the heart. If you have this liver condition and are between 18 and 65, you may help doctors understand the link between liver health and heart function.
Chandigarh, ChandigarhAges 18–65 - NCT06534372Recruiting
Factors affecting chronic pain after open-heart surgery
This study looks at factors that may lead to long-term pain after open-heart surgery. It follows patients who have coronary bypass or valve surgery to understand what might cause ongoing pain.
Ankara, AnkaraAges 18–80 - NCT06799273Recruiting
Exercise capacity and outlook in cardiac amyloidosis
This study looks at how well people with cardiac amyloidosis can exercise and how that might relate to their long-term health. You'll do a supervised bike or treadmill test while your heart and lungs are monitored.
Milan, ItalyAges 18–100 - NCT06804278Recruiting
Spectral CT for diagnosing heart inflammation in chest pain
This study uses a special CT scan (called spectral CT) to look for inflammation of the heart muscle or other heart problems in people who come to the hospital with sudden chest pain. The goal is to see if this scan can help doctors diagnose the cause of your chest pain more accurately.
BolognaAges 18 years+ - NCT07435168Recruiting
Chest pain and hidden cardiac amyloidosis study
This study looks for signs of a condition called cardiac amyloidosis in people who have chest pain but no blocked heart arteries. It aims to find hidden cases that might be missed with standard tests.
CopenhagenAges 65 years+ - NCT07436962Recruiting
Loop recorder for mitral valve heart condition
This trial tests whether a small heart monitor (loop recorder) can help people with a specific mitral valve condition called mitral annular disjunction. It's for patients who have scar tissue in their heart muscle shown on an MRI.

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,291 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.
