Clinical Trials

Do you have heart disease that requires an ICD to prevent sudden cardiac arrest? This study aims to learn what signs distinguish patients who have a higher risk of an arrhythmia that leads to sudden cardiac arrest. Researchers plan to track patients with a recent ICD replacement for 10 years. To participate in this study, you must be between 18 and 85 years old. This study is located in Washington, D.C.; Baltimore, Maryland; and Richmond, Virginia.

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 an adult with ischemic or non-ischemic cardiomyopathy? This observational study will group and follow patients at a higher risk for sudden cardiac death (SCD) who receive an implantable cardioverter defibrillator (ICD) pulse generator replacement as a prevention measure. The study hypothesizes that abnormalities of the heart, some of which are genetically determined, can be used to identify patients at high risk of SCD. To participate in this study, you must be between 18 and 85 years old and have ischemic or non-ischemic cardiomyopathy. You must also be getting your initial ICD implant for primary prevention or a programmed generator replacement if the ICD was originally implanted for SCD primary prevention. The study takes place in Baltimore, Maryland; Richmond, Virginia; and Washington, DC.
