Study on heart and lung effects of BPA in CTEPH
This study uses special heart scans (CMR with 4D flow) to see how a procedure called BPA affects blood flow in the heart and lungs for people with a rare type of high blood pressure in the lungs (CTEPH). It may help doctors understand how well BPA works beyond just symptoms.
Bad Nauheim, HesseAges 18–99 - NCT05841056RecruitingPhase 3
Short amiodarone treatment to prevent new heart rhythm after surgery
This trial studies whether a short course of amiodarone started right after heart surgery can reduce problems from new-onset atrial fibrillation (a common fast heart rhythm) or flutter. It may help some patients avoid ongoing rhythm issues and improve recovery soon after discharge.
Hamilton, OntarioAges 18 years+ - NCT06937658Recruiting
Better remote care for heart device patients
This study tests a new alert system for people with pacemakers or defibrillators that can send information directly to your care team. The goal is to improve how quickly problems are found and treated.
Boston, MassachusettsAges 18 years+ - NCT06930443Recruiting
Oxygen use and organ injury after heart-lung bypass surgery
This trial looks at how oxygen is used during heart surgery that uses a heart-lung machine, and whether low oxygen levels can lead to organ damage. It may help doctors better understand how to protect patients during surgery.
Uppsala, SwedenAges 18 years+ - NCT06715371Recruiting
Heart chamber measurements during heart surgery
This study compares two types of ultrasound of the heart—one done on the chest and one done through the throat—to see if they give similar measurements. It may help people having planned heart surgery who have normal heart function.
Toronto, OntarioAges 18 years+ - NCT06774365Recruiting
Heart imaging and blood tests for transplant rejection detection
This study uses advanced heart imaging and blood tests to detect a type of rejection that can happen after a heart transplant. It may help doctors diagnose antibody-mediated rejection earlier and more accurately.
Bari, BariAges 18 years+ - NCT06900257Enrolling by invitation
Fetal heart function in fasting pregnant women
This study looks at how babies' hearts work when mothers have been fasting for at least 10 days. It may help understand if fasting affects the baby's heart health.
SanliurfaAges 18–50 - NCT06895603Recruiting
New cuff to measure blood flow during heart procedures
This trial tests a new upper-arm cuff that may measure your heart's blood flow without needing an extra tube in your heart. If you already need a special heart catheter and a wrist arterial line, this study will see if the cuff works just as well.
Charlottesville, VirginiaAges 18 years+ - NCT07267013RecruitingPhase 2
Testing clindamycin instead of vancomycin in aortic heart surgery
This study tests if clindamycin, a common antibiotic, works as well as vancomycin to prevent infections during heart surgery on the aorta (the main artery from the heart). Patients must be having planned morning surgery with the heart-lung machine and understand French.
Nantes, FranceAges 18 years+ - NCT06814951Recruiting
Breathing & movement technique after heart bypass surgery
This study tests a special breathing and movement technique called the Thoraco-abdominal Rebalance Method to see if it helps people recover faster after heart bypass surgery.
Porto Alegre, Rio Grande do SulAges 35 years+ - NCT05261204Enrolling by invitation
TAVR vs surgery for narrowed aortic valve
This trial compares a less invasive valve procedure called TAVR with standard open-heart surgery to replace a narrowed aortic valve. It studies which approach works best for people who are considered higher risk for surgery.
Saint-DenisAges 18–90 - NCT05951088Recruiting
Mobile app follow-up for heart patients with AF or heart failure
This study tests a smartphone or tablet app that helps keep track of follow-up care for people with certain heart rhythm problems (AF/atrial flutter) and/or heart failure. If you join, you would be followed long-term to see whether the app can support ongoing care.
Edegem, AntwerpAges 18 years+ - NCT07361445Recruiting
Study of a device to help access the heart during ablation
This trial tests a new device to help doctors safely enter the left side of your heart during a procedure called ablation. If you are already scheduled for an ablation or a combined ablation and left atrial appendage closure, this study may be an option.
Jonesboro, ArkansasAges 18 years+ - NCT05740397Recruiting
Testing blood pressure targets during heart-lung bypass
This trial compares different strategies for keeping a specific blood pressure level during heart-lung bypass surgery. It may help reduce complications by finding the safest blood pressure target during the operation.
VeronaAges 18–80 - NCT05954559RecruitingPhase 4
MRI study testing a strong-contrast heart scar scan agent
This Phase 4 study checks whether a stronger MRI contrast dye (given in a higher “relaxivity” form) can better help doctors assess heart muscle scar tissue. You may be eligible if you already joined a prior similar MRI contrast study and can safely undergo another heart MRI.
Baltimore, MarylandAges 21 years+ - NCT06569212RecruitingPhase 4
Beta-blocker to reduce heart damage after brain bleed
This trial tests whether a common beta-blocker (metoprolol) can protect the heart from injury and reduce inflammation after a bleed in the brain (subarachnoid hemorrhage). It may help patients recover better after this type of stroke.
