Clinical Trials

Are you an adult with atrial fibrillation? In this study, researchers are comparing a continuous direct oral anticoagulation (DOAC) use versus time-limited (1 month) DOAC guided by an AF-sensing Smart Watch (AFSW) for persons with atrial fibrillation and a moderate risk of stroke. Participants must be between the ages of 22 and 85 and have a history of atrial fibrillation. The study is taking place at locations in California, Colorado, Florida, Georgia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Texas, Virginia, Wisconsin, and Washington, D.C.

Did you develop atrial fibrillation after coronary artery bypass graft (CABG) surgery? Did you develop atrial fibrillation after a coronary artery bypass grafting (CABG) surgery? This study is looking at how well oral anticoagulation medicines work to prevent complications, such as blood clots and heart attack, for patients who experience post-operative atrial fibrillation (POAF). This study is in multiple locations around the country.

Are you a woman with coronary microvascular dysfunction? In this clinical trial, researchers are studying coronary microvascular dysfunction, which occurs when there are problems in the small blood vessels in the heart. It frequently causes chest pain and is more common in women. The researchers want to learn how daily life and mental stress affect the heart. You may be able to participate if you are at least 45 years old, have gone through menopause, and are willing to undergo tests to measure your stress level. The study is taking place at locations in Atlanta, Georgia.
