Understanding life with an ICD: A patient interview study
This study involves one-on-one interviews with people who have an ICD to understand their experiences and quality of life. If you have an ICD and speak Dutch, you may be able to share your story in a 30–60 minute conversation.
LeuvenAges 18 years+ - NCT07253909Enrolling by invitation
Arm function in heart failure with ICD or CRT devices
This study looks at how well people with heart failure and certain heart devices (ICD or CRT) can use their arms and hands. It aims to understand if these devices affect upper body function.
Ankara, SamanpazarıAges 18 years+ - NCT07156851Recruiting
Belgian registry of implanted EV-ICD devices
This study registers patients who have had or will have an extravascular implantable cardioverter-defibrillator (EV-ICD) placed. It aims to track how the device performs and any complications in real-world use.
AntwerpAges 18 years+ - NCT07084142Recruiting
Digital aid for ICD decisions
This study is developing a digital tool to help people 70 and older with heart failure decide whether an ICD (a device that prevents dangerous heart rhythms) is right for them. Participants will help test and improve this tool.
San Francisco, CaliforniaAges 60 years+ - NCT06964464RecruitingPhase 4
Comparing two heart failure medications in ICD patients
This trial compares two beta-blocker medications, carvedilol and metoprolol succinate, to see which one works better for people with heart failure who have an implantable cardioverter defibrillator (ICD). If you are currently taking metoprolol succinate, you may be able to switch to carvedilol and help researchers find the best treatment.
Scottsdale, ArizonaAges 18 years+ - NCT06935526Enrolling by invitation
Mobile app and phone calls for ICD patients
This trial tests if a mobile app and regular phone check-ins can help reduce anxiety and improve confidence for people with an implantable cardioverter-defibrillator (ICD). It may be a good fit if you have an ICD, feel some anxiety, and use an Android smartphone.
Antalya, KonyaaltıAges 18 years+ - NCT02275637Recruiting
Testing heart-rhythm monitoring from implanted devices
This study checks how well implanted heart rhythm devices can detect rhythm problems in everyday patients. It may help improve detection and follow-up over the next year.
BergamoAges Any age - NCT06667505Recruiting
Testing an online education program for ICD patients
This trial tests an online educational program designed to help people with heart failure who have or are waiting for an ICD (a device that helps control heart rhythm). It includes patients, their caregivers, and healthcare professionals to see if the program improves understanding and outcomes.
Belfast, County AntrimAges 18 years+ - NCT06654284Enrolling by invitation
