ShanghaiAges 18–65 - NCT06396767Recruiting
Breathing test before heart surgery to predict lung problems
This study uses a simple breathing test before scheduled heart surgery to see if it can help predict breathing or lung complications after the operation. The results may help doctors identify patients who need extra support during recovery.

Monitoring glycocalyx to predict complications after heart surgery
This study will see if measuring a substance in your blood (glycocalyx) can help doctors predict problems after heart surgery that uses a heart-lung machine. The goal is to improve care after surgery.
RouenAges 18–80 - NCT06786819Recruiting
Recovery app after heart bypass surgery
This study tests whether a smartphone app that helps you follow a recovery plan can shorten the time you need to stay in the hospital after coronary artery bypass (heart bypass) surgery. If you are scheduled for this surgery, have a smartphone, and are comfortable using it, this app might help you get home sooner.
São Paulo, São PauloAges 18 years+ - NCT07024420Recruiting
Sigh breathing during heart surgery with heart-lung machine
This study tests if adding occasional deep breaths (sighs) during heart surgery helps patients recover better after using the heart-lung machine. It is for people having planned (not emergency) heart surgery.
Nanjing, JiangsuAges 18 years+ - NCT06523166Recruiting
Comparing heart CT and ultrasound for Watchman device checking
This study compares two types of heart imaging (a CT scan and an ultrasound) to see how well they work at checking the Watchman device after it is placed. The goal is to see if the CT scan might be a good alternative to the standard ultrasound for follow-up.
Los Angeles, CaliforniaAges 18 years+ - NCT07417462Recruiting
Pain relief after heart surgery to help you recover faster
This trial tests a combination of pain medicines given during cardiac surgery to reduce pain and speed up recovery. It may help patients who are having a first-time bypass surgery through a standard breastbone incision.
AsyutAges 40–60 - NCT07564531Recruiting
Safe sedation for heart catheterization in children
This study tests whether a combination of two sedative medications (dexmedetomidine and ketamine) works safely and effectively to keep children calm and still during heart catheterization—a procedure where a thin tube is guided through blood vessels to the heart for diagnosis or treatment.
HanoiAges Up to 18 years - 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 - NCT07385170Recruiting
Glucose monitor accuracy during heart surgery
This trial checks how well a continuous glucose monitor works during heart surgery. It aims to help manage blood sugar levels more safely in the operating room.
SeoulAges 19 years+ - NCT07348510Recruiting
Diuretic Effect of Aminophylline and Furosemide in Heart Surgery Patients
This study is testing if a combination of two medicines (aminophylline and furosemide) can help the kidneys produce more urine after heart surgery. It may help reduce fluid buildup and protect kidney function.
CairoAges 18–65 - NCT07164911Recruiting
Heart failure rehab: who benefits most?
This study looks at what helps people with heart failure get the most out of a cardiac rehab program. It aims to find out which patients improve the most after completing phase II cardiac rehab.
CorbieAges 40–75 - NCT07133984Recruiting
Heart imaging study for people with heart failure and blocked arteries
This study uses heart MRIs to learn more about people who have heart failure and significant blockages in their coronary arteries. If you are planning to have bypass surgery or a stent, the study may be a fit.
Brooklyn, New YorkAges 18 years+ - NCT07490184Recruiting
Heart check vs frailty score for hip surgery

- 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.
