Stress hormone system study after heart surgery
This study looks at how your body's stress hormone system (the HPA axis) works after heart surgery if you develop vasoplegic syndrome (a serious drop in blood pressure). The goal is to understand if giving extra steroids might help. If you are scheduled for heart surgery with a heart-lung machine, you may be able to join.
Paris, Île-de-France RegionAges 18 years+ - NCT06355063Recruiting
CellFX device for atrial fibrillation during open-heart surgery
This trial tests a new device called CellFX that uses nanosecond pulsed field ablation to treat atrial fibrillation during open-heart surgery. It may help you if you already need heart surgery and also have AFib.
ViennaAges 18–85 - NCT06287619RecruitingPhase 2
IV iron after heart surgery for iron deficiency
This trial tests whether giving iron through a vein after heart surgery can help fix low iron levels and improve recovery. It is for people who have iron deficiency (with or without anemia) before their planned heart surgery.
Kingston, OntarioAges 18 years+ - NCT06294119Recruiting
Brain-heart-vessel interaction study in heart surgery patients
This study looks at how your brain, heart, and blood vessels work together during heart surgery. It uses simple tests to measure these connections, which may help doctors better understand your health.
San Donato Milanese, MilanAges 18 years+ - NCT05873543Recruiting
Smartphone-based exercise program for heart failure recovery
This trial tests whether a hybrid heart-rehabilitation program that uses a smartphone helps people with heart failure feel better and safely exercise. If you’re eligible, you’ll likely get guided exercise training with help from a phone app.
TaipeiAges 18–80 - NCT02781922RecruitingPhase 3
Stem cell infusion for single-ventricle heart failure during surgery
This trial tests whether an infusion of heart stem/progenitor cells can improve outcomes for children with a single working heart chamber (single ventricle) who are scheduled for the next surgical stage (Glenn or Fontan). It may help the heart function after surgery, but participation depends on several heart, lung, brain, and overall health safety criteria.
KanagawaAges birth–6 years - NCT06244199Recruiting
Transition to cardiac rehabilitation for veterans with heart disease
This study tests a program that helps Veterans with heart disease start cardiac rehabilitation (a supervised exercise and education program to improve heart health) while they are still in the hospital. It aims to overcome barriers like other health problems and frailty, and may add up to 2 days to your hospital stay.
Boston, MassachusettsAges 18 years+ - 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 - NCT06241651Recruiting
Comparing two types of pacemakers for heart failure patients
This trial tests if a new pacemaker method (CSP) works better than the standard method (BiVP) for people with heart failure who already have a right ventricular pacemaker and need an upgrade.
Nanjing, JiangsuAges 18–80 - NCT04662970Recruiting
Imaging after a heart device to optimize pacing settings
This study uses a heart MRI (a special scan) to better map the heart’s electrical activity, with the goal of fine-tuning settings on your implanted pacing device. It’s meant to improve how well the device coordinates your heartbeat.
Innsbruck, TyrolAges 18 years+ - NCT06212791Recruiting
