Lusaka, Lusaka ProvinceAges Any age - NCT06101108Recruiting
Early heart screening in back surgery patients
This trial checks people having back surgery for spinal stenosis to see if they have an early sign of heart amyloidosis (a protein buildup in the heart). The goal is to find this condition early so it can be treated before it causes problems.
BrugesAges 60 years+ - NCT05741918Recruiting
Testing a monitor to measure heart output in sick children
This study checks whether a bedside “metabolic monitor” can accurately measure how well the heart is pumping (heart output) in children in the intensive care unit. It may help clinicians better understand and manage circulation using measurement methods during critical care.
MontpellierAges 4 weeks–17 years - NCT04604418Recruiting
Tracking outcomes during non-heart procedures in children with heart defects
This study looks at how children with congenital heart disease do during routine non-heart procedures, including medical or minor treatments that are not heart-related. It also measures how much health care they use afterward, which may help improve care planning for families.
Los Angeles, CaliforniaAges Up to 21 years - NCT05812755RecruitingPhase 4
Study drug effects on blood vessels and organs in heart surgery
This Phase 4 trial studies vericiguat-like stimulation (a type of medicine that affects blood-vessel signaling) around the time of planned open-heart surgery. It aims to see whether this can change blood-vessel “reactivity” and reduce injury to organs during and after surgery.
Nashville, TennesseeAges 18 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.
Chicago, IllinoisAges 18 years+ - NCT07343297Recruiting
Ask questions about clinical trials
This study helps people learn about clinical trials and find out if they might be a good fit. It is for patients who are already getting treatment at a Karmanos or McLaren center and can read English well enough to complete surveys.
Bay City, MichiganAges 18 years+ - NCT07506499Recruiting
Cardiac Rehab for Hospitalized Heart Failure Patients
This study tests whether a cardiac rehabilitation program (a supervised exercise and education plan) helps people recovering in the hospital from severe heart failure. It is for those aged 45–65 whose heart pumps less than 40% of its normal amount.
Banī Suwayf, Beni-Suef GovernorateAges 45–65 - NCT07079904Recruiting
Laser and ultrasound for IV placement in heart surgery
This trial tests a new method using laser and ultrasound guidance to place a small tube (IV) in a vein for patients having heart surgery. It may help make the procedure faster and safer.
Nanjing, JiangsuAges 18–80 - NCT06823778Recruiting
Preventing irregular heartbeat after heart surgery with radiofrequency
This trial tests whether using radiofrequency energy to isolate a small area in the heart's left upper chamber can prevent a common irregular heartbeat (atrial fibrillation) after heart surgery.
Moscow, MoscowAges 18 years+ - NCT06716840Recruiting
Remimazolam for sedation after heart surgery
This trial tests a medication called Remimazolam Besylate to sedate patients who need a breathing tube after heart surgery. The goal is to help patients relax while they recover in the intensive care unit.
