Cardiac MRI test in people with prior heart attack
This study uses special heart MRI scans to improve how heart images are made and interpreted. You may be asked to undergo MRI testing to help compare scans in people with a past heart attack and healthy volunteers.
Aberdeen, AberdeenshireAges 20 years+ - NCT04522622RecruitingPhase 4
Teriparatide for low bone turnover in advanced kidney disease
This trial tests teriparatide (a hormone-like bone medicine) to improve bone health in people with advanced chronic kidney disease who are at risk for weak, low-turnover bone. It may help by changing how quickly your bones break down and rebuild.
AalborgAges 18–120 - NCT04556188Recruiting
Study to improve cardiac surgery services for rheumatic heart disease
This study looks at whether building a better, sustainable cardiac surgery service can reduce the burden of rheumatic heart disease. It focuses on patients who need cardiac surgery at a specific hospital during a training and research program.
Addis AbabaAges 14 years+ - NCT04587648Recruiting
Treating cardiac amyloidosis in heart failure with preserved ejection
This trial studies people with heart failure with preserved ejection fraction (HFpEF) and cardiac amyloidosis (an abnormal protein buildup in the heart). It may help researchers understand better treatment for symptoms and heart function in this group.
TaipeiAges 60 years+ - NCT04617717Recruiting
Personalized treatment for abnormal heartbeats needing ablation
This trial studies a customized treatment plan for people who have premature ventricular beats (PVCs) and have been referred for a procedure called PVC ablation. It may help doctors choose the best approach for stopping these extra heartbeats.
OsloAges 18–90 - NCT04662970Recruiting
Imaging after a heart device to optimize pacing settings
This study uses a heart MRI (a special scan) to better map the heart’s electrical activity, with the goal of fine-tuning settings on your implanted pacing device. It’s meant to improve how well the device coordinates your heartbeat.
Innsbruck, TyrolAges 18 years+ - NCT04667494RecruitingPhase 4
Ultrasound treatment for heart amyloidosis
This trial studies whether ultrasound therapy can help people with amyloidosis that affects the heart. It’s aimed at improving heart-related outcomes in AL or transthyretin (ATTR) cardiac amyloidosis.
Boston, MassachusettsAges 18–90 - NCT04696523RecruitingPhase 2
Xenon gas for brain injury after a ruptured brain aneurysm
This Phase 2 study tests whether xenon gas can reduce brain injury after an aneurysmal subarachnoid hemorrhage (a bleeding caused by a brain aneurysm). It aims to help people who are very sick right after the bleeding by improving brain function outcomes.
Helsinki, HelsinkiAges 18 years+ - NCT04701723Recruiting
Breathing training to help after trauma stress
This pilot study tests whether “cardiac coherence” breathing exercises can help prevent ongoing (chronic) post-traumatic stress disorder after a recent traumatic event. It’s meant for people who are newly dealing with an acute stress reaction, soon after the event.
