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+ - NCT06405516Recruiting
Platelet function after heart surgery
This study watches how well platelets (cells that help blood clot) work in people who have high-risk heart surgery using a heart-lung machine for more than 2 hours. The goal is to learn more about bleeding risks after surgery.
BernAges 18 years+ - NCT07133984Recruiting
Heart imaging study for people with heart failure and blocked arteries
This study uses heart MRIs to learn more about people who have heart failure and significant blockages in their coronary arteries. If you are planning to have bypass surgery or a stent, the study may be a fit.
Brooklyn, New YorkAges 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 - NCT07154394Recruiting
Heart amyloid and function in Alzheimer's disease
This study examines whether amyloid plaques in the heart affect heart function in people with Alzheimer's disease. It uses brain amyloid PET and MRI scans to explore a potential link.
Essen, North Rhine-WestphaliaAges 18 years+ - NCT06735521Recruiting
Heart MRI stress test for Fontan circulation
This study uses a special heart MRI with a medicine that stresses the heart (like exercise) to look at blood flow in people who have had the Fontan surgery. The goal is to better understand how the heart works after this surgery.
StockholmAges 18 years+ - NCT04289142RecruitingPhase 4
Testing memory effects of dexmedetomidine during heart surgery
This study looks at how a sleep medicine called dexmedetomidine affects thinking and memory after heart surgery. It compares cognitive outcomes over time to see if this sedation choice changes long-term brain function.
Vancouver, British ColumbiaAges 60 years+ - NCT05972356Recruiting
How heart relaxation affects outcomes in heart surgery
This study looks at whether a measurement of how well the heart relaxes helps predict outcomes after heart surgery. It focuses on patients treated in Amsterdam UMC and uses care data to understand who may be at higher or lower risk.
Amsterdam, North HollandAges 18 years+ - NCT07168421RecruitingPhase 4
Landiolol to prevent fast heart rate during major surgery
This trial tests a short-acting medicine called landiolol to see if it can prevent dangerously fast heart rates during and after major surgery. It is for people who have heart risks and are having a planned non-cardiac surgery.
BernAges 45 years+ - NCT06920030Recruiting
Testing a new heart device for heart failure
This trial tests a new device that delivers a gentle electrical current to the heart to improve its pumping strength. It is for people with a certain type of heart failure caused by weak heart muscle, not a blocked artery.
Banja Luka, Republic of SrbskaAges 18–75 - NCT05966675Recruiting
Special heart pacing after TAVI to help protect heart function
This trial looks at a physiologic (more natural) heart pacing approach to prevent weakening of the heart’s main pumping chamber after TAVI. It enrolls people who recently had TAVI and now meet standard reasons for needing a permanent pacemaker.
KatowiceAges 18 years+ - NCT06817239Recruiting
Low-dose esketamine for preventing confusion after surgery in older adults
This study tests whether a low dose of the medicine esketamine can help prevent confusion after surgery in older adults at higher risk. You may qualify if you are 65 or older, planning a major non-cardiac surgery, and have certain health conditions like high blood pressure or diabetes.
Fuzhou, FujianAges 65–90 - NCT07604467Recruiting
Understanding Stem Cells in Takotsubo Heart Syndrome
