Phone-Guided CPR Training With Automated Device
This study tests whether receiving CPR instructions over the phone with help from an automated external defibrillator (AED)—a machine that can restart the heart—improves the quality of chest compressions people perform. You would practice CPR techniques during a training session.
PécsAges 16 years+ - NCT04950218Recruiting
Study risks of heart problems in people with psoriasis
This study asks adults with psoriasis about factors that may be linked to heart problems. It aims to better understand who is at higher risk, which could help guide future prevention and care.
Hellerup, CopenhagneAges 18 years+ - NCT04982419RecruitingPhase 2/Phase 3
Remote arm treatment to protect heart and kidneys in heart failure
This trial tests whether a simple “arm cuff” treatment done before a heart artery procedure can help protect the kidneys and the heart in people with congestive heart failure. If it works, it may lower the chance of kidney injury around the time of the scan/stent procedure.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT04983823Recruiting
Study aims to improve long-term heart effects after COVID
This trial looks at how persistent heart-related changes after a past COVID infection may be affected by study treatments. It mainly seeks people who are stable enough for follow-up visits and heart imaging, and who are not already on the specific heart medications required.
Melbourne, VictoriaAges 50–85 - NCT04990297Recruiting
MRI test to better predict risk in dilated heart muscle
This trial uses a heart MRI to measure details in people with dilated cardiomyopathy and reduced pumping strength. It aims to use these MRI findings to better predict your future heart risk and guide care.
Beijing, Beijing MunicipalityAges Any age - NCT05002543Recruiting
Real-world study of heart valve repair devices for multiple valves
This study checks how well and how safely CORCYM valve devices work in real-world patients with heart valve problems in the aortic, mitral, and/or tricuspid positions. It may help doctors understand expected outcomes outside of tightly controlled research settings.
Indianapolis, IndianaAges Any age - NCT05014802Recruiting
MRI scans before heart surgery to predict post-surgery atrial fibrillation
This study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
Covington, LouisianaAges 40–120 - NCT05036538Recruiting
Reducing pre-surgery stress to help prevent confusion after heart surgery
This study tests whether a stress-reducing relaxation method before heart surgery can lower the risk of postoperative delirium (sudden confusion) and longer-term thinking problems. It may help you keep clearer thinking in the days and weeks after surgery.
Bad Nauheim, HesseAges 18 years+ - NCT05049889Recruiting
Diver screening to spot risk for lung fluid after diving
This study checks whether certain personal factors can predict who may get “immersion pulmonary edema,” a condition where fluid builds up in the lungs after water exposure and diving. If you’re a diver, your results may help tailor safety steps and reduce risk.
ToulonAges 18–60 - NCT05051254Recruiting
Breathing muscle testing in children with breathing muscle weakness
This study looks at how hard it is for children to breathe and how their breathing muscles work, using specific breathing-related tests. It may help doctors better understand breathing problems and choose care more effectively.
ParisAges birth–17 years - NCT05055830Recruiting
Study blood drug levels in critically ill children
This trial measures how the study medicines move through the body and how they affect the child in the Pediatric Cardiac Intensive Care Unit. It may help doctors choose safer and better dosing for critically ill children.
Durham, North CarolinaAges birth–20 years - NCT05064709Recruiting
Test device for heart failure symptoms in some patients
This study tests whether a heart-related device called CCM can improve symptoms and daily function in people with heart failure and a moderately reduced pumping strength. It may help if you’ve had recent heart-failure-related hospital care or urgent treatment and your heart and overall health fit the study limits.
Birmingham, AlabamaAges 18 years+ - NCT05066347Recruiting
Remote heart monitoring after fainting discharge from the ER
This trial studies whether remote heart monitoring after an ER visit for fainting (syncope) can help identify dangerous heart problems. You may be enrolled only if your fainting episode seems medium- to high-risk and you’re being sent home from the ER.
Ottawa, OntarioAges 18 years+ - NCT05094843Recruiting
Mini-invasive surgery for lung cancer and heart rhythm changes
This study looks at how lung cancer surgery affects the heart’s electrical signals and stress response, using heart tracing tests (ECG) around the time of surgery. It may help doctors better understand and monitor heart risks in people having curative, minimally invasive lung cancer surgery.
Tampere, PirkanmaaAges 18 years+ - NCT05098665Recruiting
Home monitoring to help prevent hospital stays for ATTR heart disease
This trial tests whether using home weight/health tracking can help people with ATTR cardiomyopathy avoid going to the hospital. It may help by catching fluid build-up or worsening earlier so treatment can be adjusted sooner.
London, LondonAges 18 years+ - NCT05100940Recruiting
Study after a heart procedure complication
This trial looks at what happens after complications during or after a heart procedure called coronary angiography or PCI. It may help improve care and outcomes for people who experience a problem during treatment.
Minneapolis, MinnesotaAges 18 years+ - NCT05101304Recruiting
European registry for people with amyloidosis
This study collects health information from people who may have amyloidosis or who already have a confirmed diagnosis. It aims to better understand amyloidosis in real-world care across European centers, which can help future patients and treatments.
CréteilAges Any age - NCT05115214Recruiting
Device test for treating irregular heartbeat with AF ablation
This trial studies a heart procedure using the Affera SpherePVI system to treat paroxysmal (comes and goes) or persistent atrial fibrillation. It’s for people who still have symptoms despite at least one anti-arrhythmia medicine, and who are good candidates for catheter ablation.
PragueAges 18–75 - NCT05135403Recruiting
Registry study for the ASSURE wearable heart defibrillator
