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 - NCT06251713Recruiting
Fluid removal guided by VeXUS score after heart surgery
This trial tests if using a special ultrasound score (VeXUS) to guide fluid removal can improve recovery in patients with acute kidney injury after heart surgery. It compares this approach to standard care to see if it leads to better outcomes.
Bron, BronAges 18–85 - NCT07634666Recruiting
Heart Safety Monitoring During Urologic Cancer Surgery
This study tracks heart health before and after major surgery for prostate or kidney cancer in older adults. Researchers want to predict which patients might experience heart problems after surgery so they can provide better care.
SeoulAges 60 years+ - NCT05139797Recruiting
AI-guided heart ultrasound screening for suspected amyloidosis
This study tests whether an artificial-intelligence system can help decide who should get a special heart workup for a rare disease called cardiac amyloidosis. If you have signs that make doctors suspect this, the AI-guided ultrasound screening may help find it sooner.
Los Angeles, CaliforniaAges 18 years+ - NCT06664866Enrolling by invitation
AI Screening for Heart Amyloidosis
This trial tests an AI program that looks at your heart ultrasound (echocardiogram) to find possible signs of cardiac amyloidosis early. It helps doctors decide if more testing is needed.
Los Angeles, CaliforniaAges 22 years+ - NCT07707037Recruiting
Helping parents cope after a child's cardiac arrest
This study tests if providing clearer information to parents after their child's cardiac arrest can reduce fear and anxiety. It is for parents of children under 17.5 years old who are expected to leave the hospital soon.
Philadelphia, PennsylvaniaAges birth–17 years - NCT05893121Recruiting
Cardiac coherence to reduce MRI anxiety
This trial tests whether a “cardiac coherence” relaxation session can lower anxiety before and during an MRI scan. It may help people who feel very anxious about MRI procedures complete the scan more comfortably.
ToulouseAges 18 years+ - NCT07287423Recruiting
A study of a new pacemaker system for heart rhythm problems
This trial tests a new pacemaker system for people who need a pacemaker for a slow or irregular heartbeat. It aims to see if the system is safe and works well.
PragueAges 18 years+ - NCT03209674Recruiting
Registry tracking outcomes after heart and chest surgery
This is a registry that collects information from people who have heart or chest (thoracic) surgery. It may help doctors understand what improves outcomes after surgery, but it usually does not test a new drug.
Neuilly-sur-Seine, Île-de-France RegionAges Any age - NCT03261089Recruiting
Predicting brain outcome after cardiac arrest, reducing bias
This study looks at how to predict brain recovery after certain types of cardiac arrest. It aims to improve decision-making so people are not misjudged due to “self-fulfilling prophecy.”
San Francisco, CaliforniaAges 18–89 - 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+ - NCT03588286Recruiting
Check heart rhythm risk early after a heart attack
This trial tests whether a programmed heart rhythm test can better identify who needs an implanted defibrillator (ICD) soon after a heart attack. It may help prevent dangerous fast heart rhythms (tachyarrhythmias) by guiding who gets an ICD.
Boston, MassachusettsAges 18–85 - NCT03594318Recruiting
Registry for adults treated in ICU after cardiac arrest
This trial is a registry, which means the researchers collect information about people who were treated in an intensive care unit after a cardiac arrest. It may help improve understanding of outcomes and care, which can guide future treatment.
Le ChesnayAges 18 years+ - NCT03753412Recruiting
Rehab program for adults after ICU recovery on ECMO
This trial looks at a recovery and rehabilitation approach for adults who were very sick and needed a machine called ECMO to support breathing and heart function. It may help people regain strength and function after a severe ICU illness.
LondonAges 18 years+ - NCT03775954Recruiting
Fetal heart testing in high-risk pregnancies after baby loss
This study checks unborn babies’ heart signals using special scans during pregnancy and then checks the baby’s heart shortly after birth. It may help researchers understand why certain high-risk pregnancies can lead to fetal demise and improve care.
Madison, WisconsinAges 18 years+ - NCT03826524RecruitingPhase 4
Finding the best epinephrine dose after EMS-treated cardiac arrest
This study compares two epinephrine doses during the emergency treatment of out-of-hospital cardiac arrest. It aims to find a dose that works better and more safely for people who are in a shockable heart rhythm when paramedics arrive.
Victoria, British ColumbiaAges 18 years+ - NCT06728826Recruiting
Preventing atrial fibrillation after heart surgery with pericardiotomy
This study tests if opening the sac around the heart (pericardiotomy) can lower the chance of developing an irregular heartbeat called atrial fibrillation after heart surgery. It is for people having surgery on the heart's valves, major blood vessels, or arteries.
ShanghaiAges 18 years+ - NCT04024917Recruiting
Cardiac coherence training to reduce anxiety before abdominal surgery
This trial tests whether “cardiac coherence” breathing/relaxation practice can lower anxiety in people with peritoneal cancer who are scheduled for a major surgery. It may help by calming stress before and around the operation.
Montpellier, HéraultAges 18 years+ - NCT04073420Recruiting
Cardiac surgery registry to track Medtronic device outcomes
This registry collects real-world information from people who have had—or plan to have—an eligible Medtronic cardiac surgery device. It aims to better understand how these treatments do over time and help guide future care.
