Elizabeth, New JerseyAges 18 years+ - NCT06034405Recruiting
Checking spine tissue for heart amyloidosis signs
This trial is looking at leftover tissue from past spine surgeries to see if it contains signs of a heart condition called TTR amyloidosis. It may help find people who have this condition early.
Beverly Hills, CaliforniaAges 50 years+ - NCT06015191Recruiting
Remote heart rehab for teens with congenital heart disease
This trial tests a home-based cardiac rehab program for adolescents with certain types of congenital heart disease. It aims to help you exercise safely and improve your fitness using online coaching and monitoring.
Kansas City, MissouriAges 12–19 - NCT06019845Recruiting
MAGiC heart ablation study with magnetic navigation
This study tests a new magnetic system (MAGiC) to guide heart ablation procedures for people with irregular heartbeats. It aims to see if using magnets to steer catheters is safe and effective.
CopenhagenAges 18 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+ - NCT05879432RecruitingPhase 2
Peptide treatment to prevent or lessen kidney injury after heart surgery
This Phase 2 trial tests an LSALT peptide given around the time of “on-pump” heart surgery to help prevent or reduce acute kidney injury (a sudden drop in kidney function). It may help people who are at higher risk for kidney injury during or after surgery.
Calgary, AlbertaAges 18 years+ - NCT05817851RecruitingPhase 2
Vitamin C by vein after cardiac arrest shock
This Phase 2 study tests whether early high-dose vitamin C given through a vein can improve outcomes for people who remain unconscious after an out-of-hospital cardiac arrest with shock. It may help by supporting recovery during the time when the body is under severe stress.
AmiensAges 18 years+ - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT05830422Enrolling by invitation
Predicting late thinking problems after cardiac arrest
This study looks at how to predict delayed cognitive (thinking) impairment in people who survived a cardiac arrest but initially seemed neurologically okay. It may help identify who is at higher risk so follow-up and support can be planned earlier.
Daejeon, Seo-guAges 18 years+ - NCT05819528Recruiting
Study of primary cardiac lymphoma treated with anti-CD20 therapy
This trial looks at people with lymphoma that involves mainly the heart (and possibly the lining around the heart) and was treated first with chemotherapy plus an anti-CD20 antibody. The goal is to understand outcomes from this specific treatment approach in patients diagnosed over a defined time period.
Bergamo, BergamoAges 18 years+ - NCT05786274Recruiting
Predicting stroke risk after heart surgery using heart signals and MRI
This study looks at ways to predict harmful brain and blood-vessel side effects after heart surgery. It may help doctors identify higher-risk patients sooner so they can monitor them more closely.
San Donato Milanese, MilanAges 18 years+ - NCT05788120Recruiting
Study heart rhythm problems in adults on VA ECMO
This study looks at how often abnormal heart rhythms happen and how serious they are in adults who are supported with VA ECMO for severe heart failure. It mainly involves using medical information, aiming to better understand complications in this critical situation.
AngersAges 18 years+ - NCT05765175Recruiting
Radioablation versus repeat ablation for hard-to-treat VT
This trial compares a heart procedure using targeted radiation (called radioablation) to a repeat catheter ablation for people with high-risk, hard-to-control ventricular tachycardia (VT). It aims to find which approach is safer and works better after standard ablation and amiodarone have not stopped the abnormal rhythm.
Los Angeles, CaliforniaAges 18 years+ - NCT05760287Recruiting
Study of heart ultrasound findings in cardiac amyloidosis
This study looks at how cardiac amyloidosis shows up on heart imaging, especially ultrasound (echocardiography). It may help doctors better describe and track the condition using your exam and test results.
Roma, RMAges 18 years+ - NCT05714618Recruiting
Heart inflammation after stroke
This study uses a special heart MRI to look for inflammation after a stroke. It aims to understand if the brain injury affects the heart, which could lead to better care.
London, OntarioAges 18 years+ - NCT05651945Recruiting
Cardiac rehab program for people after a stroke
This trial studies a supervised cardiac rehabilitation program for people after they have had a stroke. It may help improve heart-related fitness and recovery safety after stroke, especially for patients who need a tailored rehab approach.
Edison, New JerseyAges 18 years+ - NCT05664308Recruiting
