Frailty Score and Blood Pressure Changes During Surgery
This study looks at a simple scoring system (EASIX) that predicts whether older or frail patients will experience dangerous blood pressure drops when anesthesia is given before surgery. Understanding this risk might help doctors better protect vulnerable patients during their operations.
KonyaAges 18 years+ - NCT07632586Recruiting
First-in-Human Heart Pump Implant Study
This trial tests a new tiny heart pump called the Icoms Flowmaker for patients with severe heart failure who cannot have a standard heart pump. The device may help your heart pump blood better and improve your ability to do daily activities.
PragueAges 18–80 - NCT07632131Recruiting
Storytelling therapy to prevent PTSD after heart surgery
This study tests whether a special therapy called narrative exposure—where you talk through your surgery experience with a trained counselor—can help prevent PTSD (post-traumatic stress) in people recovering from heart surgery in the ICU. The goal is to help you process what happened so you feel less distressed afterward.
Fuzhou, FujianAges 18 years+ - NCT07636343Recruiting
Eccentric Training for Heart Failure Recovery
This trial tests a special type of strength training (eccentric exercise, where muscles lengthen under load) for people with heart failure who have reduced pumping ability. The goal is to improve your exercise capacity and heart function safely.
EdegemAges Any age - NCT07630402Recruiting
Heart Imaging Study for Women With Early Breast Cancer
This study helps doctors find the best way to monitor heart health in women with HER2-positive breast cancer who are receiving a type of targeted chemotherapy. The goal is to catch any heart problems early and keep you safe during treatment.
Rochester, New YorkAges 18–79 - NCT07625553RecruitingPhase 2
Relaxin Agonist to Protect Kidneys During Heart Surgery
This study tests whether a drug called R2R01 can help protect your kidneys during major heart surgery. Heart surgery can sometimes damage the kidneys, and this trial is looking to see if this new medication reduces that risk.
MilanAges 18 years+ - NCT07624409Enrolling by invitationEarly Phase 1
Occupational health study for high-altitude workers
This study examines how working at high altitudes (where there is less oxygen in the air) affects employees at an astronomical observatory in Chile. Researchers want to understand health impacts and develop better support for people working in these extreme conditions.
San Pedro de Atacama, AntofagastaAges 20–50 - NCT07620925Recruiting
Aortic Valve Calcium Score Study Using Heart Ultrasound
This study develops and tests a new way to diagnose severe aortic stenosis (narrowing of the aortic valve) by measuring calcium buildup on the valve using heart ultrasound. If you're already getting both an ultrasound and a CT scan of your heart, this study compares how well the ultrasound method can identify severe stenosis.
BolognaAges 18 years+ - NCT07622823Recruiting
Nerve Blocks to Reduce Pain After Heart Surgery
This study tests whether special numbing injections around nerves (called fascial plane blocks) can help reduce pain and improve recovery after planned heart surgery. The goal is to see if this technique helps patients manage pain better and recover faster.
AntalyaAges 18 years+ - NCT03204357Recruiting
Using your own blood after heart-lung machine surgery
This trial studies giving a “fresh” blood transfusion from your own blood after heart surgery that uses a heart-lung machine. It may help patients avoid needing donated blood, but it only works for people who meet specific safety and timing requirements.
Aurora, ColoradoAges 18–90 - NCT02856620Recruiting
Study heart function and frailty in people with aortic valve narrowing
This study looks at how heart mechanics, blood markers, and frailty relate to symptoms and heart measurements in people with aortic stenosis (a stiff, narrowed heart valve). It may help doctors better understand who is at higher risk and how disease changes over time.
Montreal, QuebecAges 18 years+ - NCT05760924Recruiting
Testing a new heart pacing method for CRT nonresponders
This trial tests whether a different pacing approach called left bundle branch pacing can improve outcomes and heart structure changes in people who did not improve with standard biventricular CRT. It may help some patients with ongoing heart failure symptoms and weak heart pumping.
TomskAges 18–80 - NCT04920565Recruiting
Hemoperfusion with Polymyxin B for septic shock after heart surgery
This trial studies a blood-filter treatment (hemoperfusion with Polymyxin B) to reduce harmful substances in the blood for people who develop septic shock after heart surgery. It may help by lowering inflammation and improving safety, but it also requires meeting specific signs of severe infection and blood/bleeding conditions.
MoscowAges 18–80 - NCT04882488Recruiting
Testing heart scan measurements in severe aortic valve narrowing
This trial compares two pressure-based measurements of blood flow in the coronary arteries with a PET heart scan in people with severe aortic valve stenosis. It may help doctors choose the most accurate way to assess blood flow and guide care during valve treatment.
Bad Oeynhausen, North Rhine-WestphaliaAges 65 years+ - NCT07618741Recruiting
Improving AF Ablation Outcomes in Patients with Obesity
This study tests whether special care strategies can help obese patients have better results after a catheter ablation procedure for atrial fibrillation (a heart rhythm problem). Catheter ablation uses heat or cold to fix the irregular heartbeats.
TaipeiAges 20 years+ - NCT07615023Recruiting
Blood cell changes and heart attack recovery
This study looks at how certain harmless changes in blood cells affect recovery after a first heart attack. It may help doctors understand why some people recover better than others.
Innsbruck, TyrolAges 18–75 - NCT07617376RecruitingPhase 4
Flu shot before leaving hospital after heart problems
This study tests whether giving a flu vaccine to patients before they leave the hospital after a heart condition improves their health. The vaccine may help protect your heart and prevent serious flu complications while you recover.
