CopenhagenAges 18–65 - NCT05452356Recruiting
Testing a phone-based care plan for people with heart conditions
This trial tests a phone app that helps deliver organized “care plans” for people with cardiovascular (heart/vessel) conditions. You might join to see if this phone-based support improves how care is delivered and helps you manage your condition.
London, OntarioAges 18 years+ - NCT05486884Recruiting
Blood pressure goal after out-of-hospital cardiac arrest
This study looks at whether targeting a specific blood pressure after a cardiac arrest can improve outcomes. It is mainly for people who are in intensive care and need a breathing machine because they are in a deep coma.
BrestAges 18 years+ - NCT05523999Recruiting
Recognizing out-of-hospital cardiac arrest in emergency calls
This study looks at how emergency dispatchers and communication systems can better recognize when a person may be in cardiac arrest during ambulance call handling. It may help EMS teams act faster, potentially improving outcomes.
PontoiseAges 18 years+ - NCT05593679Recruiting
Registry study for heart PYP scans in possible ATTR amyloidosis
This study collects information from adults who have been diagnosed with, or are being checked for, ATTR amyloidosis (a condition where abnormal protein builds up in the body) using a heart PYP scan. Your participation may help doctors better understand how these scans relate to diagnosis and follow-up over time.
New Taipei CityAges 20 years+ - NCT05694572Recruiting
Device follow-up for certain MicroPort CRM heart implants
This study checks how well specific MicroPort CRM heart devices and leads work in real life over time. If you already have one of these FDA/market-approved implants and can be followed yearly, the study helps the company monitor safety and performance.
LisbonAges 18–90 - NCT05698277Recruiting
Ultrasound to track baby heart function in heart disease
This study uses automated ultrasound measurements to track how a baby’s heart is working during pregnancy. It compares babies who have a specific congenital heart problem with babies without it, to understand what ultrasound can detect.
Sydney, New South WalesAges 18 years+ - NCT05724121Recruiting
Study heart rhythm changes during BTK or venetoclax treatment
This observational study tracks how your heart rhythm (heartbeat pattern) changes while you take a BTK inhibitor or venetoclax. It may help doctors better understand heart rhythm risks in people receiving these cancer-related medicines.
Bethesda, MarylandAges 18–110 - NCT05776797Recruiting
Ablation vs best medicines for CRT patients with permanent atrial fibrillation
This trial compares two approaches—an AV junction ablation procedure versus continued best medical treatment—in people who already have a heart device for heart failure (CRT) but still have ongoing permanent atrial fibrillation. It aims to improve how well your heart rhythm is controlled and how effectively the device can pace your heart.
Liberec, Liberec RegionAges 18–85 - NCT05877755Recruiting
Tests a new heart MRI image method
This study checks whether a new, higher-detail heart MRI technique can produce reliable heart images. You might help researchers improve how doctors see and assess the heart during routine MRI care.
PessacAges 18 years+ - NCT05895838RecruitingPhase 3
Trial for medicines after out-of-hospital cardiac arrest
This Phase 3 trial studies treatments given after a person survives an out-of-hospital cardiac arrest to improve recovery and survival. It is for patients who stay unconscious for a short time after circulation returns, and who meet safety conditions.
Copenhagen, Capital Region of DenmarkAges 18 years+ - NCT05917717Recruiting
Test a care bundle for adults after witnessed cardiac arrest
This trial studies a “care bundle” approach using special devices to improve care after an out-of-hospital or witnessed cardiac arrest. It may help by standardizing emergency treatment for people right after their heart stops.
Southampton, EnglandAges 18–120 - NCT05933083Recruiting
In-person vs telehealth heart rehab comparison study
This study compares whether heart rehabilitation done in person or by telehealth (video/phone) works as well for people with certain heart conditions. It may help you and others choose the safest and most effective way to receive cardiac rehab.
San Francisco, CaliforniaAges 18 years+ - NCT06047782Recruiting
MRI study of atrial scarring and stroke risk
This study uses a special heart MRI to look for scarring in the upper chambers of the heart (atria) that might cause hidden atrial fibrillation after a stroke with no known cause. It may help explain why the stroke happened and guide future treatment.
DijonAges 18 years+ - NCT06066970Recruiting
Studying heart markers after valve surgery
This trial uses a special MRI and blood tests to see how heart muscle is affected after aortic or mitral valve surgery. It may help doctors better understand and monitor heart recovery.
Freiburg im Breisgau, Baden-WurttembergAges 18 years+ - NCT06229418Recruiting
Testing drone delivery of AEDs for rural cardiac arrests
This study is testing whether drones can deliver AEDs (devices that restart a stopped heart) more quickly to people having a cardiac arrest in rural areas. It looks at people whose heart stopped before emergency help arrived and who received a shock from a bystander's AED.
Clemmons, North CarolinaAges 18 years+ - NCT06323668Recruiting
Device removal vs full medical treatment for infected heart devices
