Seattle, WashingtonAges 18 years+ - NCT03588286Recruiting
Check heart rhythm risk early after a heart attack
This trial tests whether a programmed heart rhythm test can better identify who needs an implanted defibrillator (ICD) soon after a heart attack. It may help prevent dangerous fast heart rhythms (tachyarrhythmias) by guiding who gets an ICD.
Boston, MassachusettsAges 18–85 - NCT03604133Recruiting
Registry for people getting a defibrillator implanted in a clinic
This trial is a registry that collects information about outcomes after getting an implantable cardioverter-defibrillator (a device that can help correct dangerous heart rhythms). You may be invited if your doctor recommends the implant to be done at an ambulatory surgical center (a same-day surgery clinic).
Lehi, UtahAges Any age - NCT03846297Recruiting
Decision support for defibrillator placement in hypertrophic cardiomyopathy
This trial looks at how to make better decisions about whether someone with hypertrophic cardiomyopathy (HCM) should get an implantable heart defibrillator. It may help by using structured decision support to guide defibrillator implantation.
Boulogne-Billancourt, Hauts-de-SeineAges 16 years+ - NCT04446585Recruiting
Study of early help for witnessed home cardiac arrests
This study looks at witnessed sudden cardiac arrest happening in residential areas, and tests whether a new first-responder approach gets help to people faster. It may help improve outcomes after cardiac arrest by improving the timing and coordination of emergency response.
Ballerup Municipality, The Capital RegionAges 8 years+ - NCT04504188Recruiting
Adjusting beta-blocker dose for women using a wearable defibrillator
This trial checks whether doctors can use a lower or adjusted dose of beta-blocker medicine in women who are wearing a wearable defibrillator (WCD). It aims to find an approach that’s safe and works while you’re using the device for about 3 months to protect your heart.
