Recruiting studies
- NCT07177391Recruiting
Quick heart ultrasound test in the ICU
This trial tests a new way to measure how much blood your heart pumps using a simple ultrasound from under your ribs. It may help doctors monitor your condition without more invasive tests.
RouenAges 18 years+ - NCT04755764Recruiting
Compare blood-pressure medicines in early pregnancy
This trial tests how three common blood-pressure medicines (labetalol, atenolol, and nifedipine) affect blood flow in early pregnancy. It may help doctors choose the safest, most effective option for pregnant people with high blood pressure.
Huntington, West VirginiaAges 18–45 - NCT07770386Recruiting
Predicting heart trouble after child heart surgery
This study looks at whether a simple blood test can predict a serious heart problem called low cardiac output syndrome after a child has heart surgery. Doctors hope this will help them spot and treat this issue earlier, which could lead to better recovery for your child.
LilleAges Up to 17 years - NCT07810621Recruiting
Low cardiac output after heart surgery
This study looks at how well the heart pumps right after bypass surgery and whether a special monitor can help predict problems. It may help doctors support patients better after surgery.
Ankara, AnkaraAges 18 years+ - NCT06763549Enrolling by invitation
AI-powered wearable patch for heart and lung monitoring
This study tests an AI-powered wearable patch (the COR ECG) to see if it can better track heart and lung health. It may help doctors find problems earlier without needing bulky equipment.
Melbourne, FloridaAges 18 years+ - NCT06793670RecruitingPhase 4
Landiolol study for mitral valve surgery patients
This trial tests a short-acting beta-blocker called Landiolol given during mitral valve surgery to see if it helps the heart recover after surgery. It is for patients who have certain signs of heart strain before their operation.
Alessandria, PiedmontAges 18 years+ - NCT06754709Recruiting
Protein Changes in Children Having Heart Surgery
This study looks at a specific protein change in blood and heart tissue of children having heart surgery with a heart-lung machine. The goal is to understand how this protein might affect recovery.
NantesAges Up to 17 years - NCT06879769Recruiting
Better heart CT scan preparation study
This study looks at how to improve the preparation and imaging techniques for heart CT scans. It may help make the scan more comfortable and accurate for people who already have a heart CT scheduled.
Stockholm, HuddingeAges 18 years+ - NCT04114799Recruiting
Tests brain-surgery monitoring to optimize circulation
This study checks a monitoring approach during brain tumor surgery to help control blood flow and heart-related measurements. It may benefit you by making surgery safer and helping the team respond faster during the operation.
Hradec KrálovéAges 18 years+ - NCT06369818Recruiting
Heart output measurement in shock patients on life support
This study tests if a new way of measuring heart function (using sound waves and breath analysis) works well in patients who are in severe heart failure and need a heart-lung machine. It might help doctors better monitor patients after heart surgery.
MünsterAges 18 years+ - NCT07839234Enrolling by invitation
Personalized breathing support for lung injury patients
This trial tests a new way to adjust breathing machine settings for people with a lung condition called ARDS. The adjustments are based on detailed monitoring of the heart and lungs, aiming to improve recovery.
Xiamen, FujianAges 18 years+ - NCT07779720Recruiting
Personalized fluids for emergency sepsis care
This trial tests a personalized approach to giving IV fluids to patients with sepsis in the emergency department. It uses a device to monitor your heart and blood flow to help doctors decide how much fluid you need, which may improve recovery.
Murray, UtahAges 18 years+ - NCT07724262Recruiting
Testing the Argos System to measure heart blood flow
This trial is testing a new system called Argos to see if it can measure how much blood your heart pumps more easily than current methods. It is for patients already in the ICU who need a quick change in fluids or blood pressure medicine.
Le Kremlin-BicêtreAges 18 years+ - NCT07695363Recruiting
Restrictive fluids in liver transplant
This trial tests if giving less fluid during liver transplant surgery helps recovery. It is for adults with end-stage liver disease receiving a transplant.
Vancouver, British ColumbiaAges 18 years+ - NCT07516236Recruiting
Using blood oxygen levels to guide fluid treatment in septic shock
This trial is studying whether a measure of oxygen in your blood (called SvO2) can help doctors decide if giving you more fluids will help improve your blood pressure during septic shock. The goal is to make fluid treatment more precise and avoid giving too much fluid.
MenoufAges 18 years+ - NCT07445347Enrolling by invitation
Bevacizumab for severe HHT liver issues with high heart output
This study looks at how well the drug Bevacizumab works and how safe it is for people with HHT who have severe liver problems that cause their heart to pump too much blood. It aims to help doctors understand if this treatment can help manage these serious symptoms.
PoitiersAges 18 years+ - NCT07444333Recruiting
Heart function and fatigue in Friedreich's ataxia
This study looks at how the heart works during exercise and how that relates to fatigue in people with Friedreich's ataxia. You'll ride a stationary bike, and we'll measure your heart's output to understand fatigue better.
New York, New YorkAges Any age - NCT07092644Recruiting
Preeclampsia and baby heart defects: mother's heart study
This study looks at the link between preeclampsia (a pregnancy complication with high blood pressure) and a mother's heart health when her baby has a heart problem. The goal is to understand how the mother's heart adapts during pregnancy in these cases.
RomaAges 18 years+ - NCT07061548Recruiting
Predicting heart output changes during surgery using capnography
This trial uses a computer algorithm to predict changes in how well your heart pumps blood during surgery. It looks at carbon dioxide levels in your breath to make these predictions. This could help doctors adjust care in real time.
SeoulAges 19–75 - NCT06895603Recruiting
New cuff to measure blood flow during heart procedures
This trial tests a new upper-arm cuff that may measure your heart's blood flow without needing an extra tube in your heart. If you already need a special heart catheter and a wrist arterial line, this study will see if the cuff works just as well.
Charlottesville, VirginiaAges 18 years+ - NCT06679543Recruiting
How partial sleep loss affects heart function during cycling
This study looks at how a night of poor sleep affects your heart's ability to pump blood while you ride a bike. It may help find out why sleep loss can be hard on the heart.
Guelph, OntarioAges 18–50 - NCT03446326Recruiting
Check how your pacemaker changes heart pumping
This study measures how well the heart pumps at different heart rates in people with pacemakers or defibrillators. It may help doctors understand how pacing settings affect heart function.
Calgary, AlbertaAges 18–70 - NCT07454564Recruiting
Heart function and surgery risk in older adults
This study looks at how well the heart pumps blood to predict recovery after abdominal surgery in people 65 and older. It uses an ultrasound of the heart (echocardiogram) to measure heart power and a standard score to estimate surgical risk.
KonyaAges 65 years+ - NCT05700617RecruitingEarly Phase 1
Testing cardiac pumping strength in cardiogenic shock
This early study looks at how well the heart is pumping in people with cardiogenic shock, using measurements taken during a right-heart catheter (a small pressure-monitoring test). It may help doctors better assess heart function and guide next-step treatments like LVAD, heart transplant, or valve surgery.

Common questions
- Are there clinical trials for cardiac output?
- Yes. Clin2 currently lists 26 recruiting cardiac output 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 output 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 output 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.
