Chicago, IllinoisAges 18 years+ - NCT05836987RecruitingPhase 3
Smartwatch monitoring trial to guide blood thinner use for AF
This study tests whether continuous heart-rhythm monitoring with a smartwatch can better guide treatment for atrial fibrillation (AF) while you stay on a blood thinner. The goal is to improve safety and reduce stroke risk by catching AF patterns more closely.
Chicago, IllinoisAges 22–85 - NCT07324772Recruiting
Exercise program to improve symptoms in atrial fibrillation and heart failure
This study tests if starting a supervised exercise program can help older adults with both atrial fibrillation and a type of heart failure called HFpEF feel better and have a better quality of life. You'll be asked to join exercise sessions and have regular check-ins to see how you're doing.
Chicago, IllinoisAges 60–99 - NCT05963698Recruiting
Closing off a heart pouch to prevent stroke
This study tests a procedure that seals off the left atrial appendage (a small heart pouch) to help prevent stroke in people with atrial fibrillation. You may be considered if your stroke risk is high and you are already on blood-thinner medicine.
Evanston, IllinoisAges 18 years+ - NCT06056271Recruiting
Tracking AI use during AF ablation in real-world care
This trial is for people with atrial fibrillation (AF) who are having or recently had a catheter ablation procedure. It looks at how using a special artificial intelligence tool, called VX1, during the procedure affects patient outcomes.
Evanston, IllinoisAges 21 years+ - NCT04088071Recruiting
Ablation for heart rhythm problems using a specific technology
This study looks at how well catheter ablation works for treating certain heart rhythm disorders (like atrial fibrillation or ventricular arrhythmias) using a specific brand of catheters. The aim is to gather real-world data to better understand the procedure's outcomes.
Evanston, IllinoisAges 18 years+ - NCT06844227Recruiting
Virtual Visit to Manage Blood Thinners Around Surgery
This study looks at whether a virtual visit can safely manage your blood thinners around the time of a planned surgery. You would stop your medication before the procedure and restart it after, but all instructions and check-ins happen remotely (phone or video).
