PLUG Dementia Trial and MRI PLUG Dementia Sub-Study

Stopped early

Conditions studied: Atrial Fibrillation, Dementia, Cognitive Decline

In brief

PLUG Dementia Trial: Patients will be screened at Intermountain Medical Center and at Intermountain affiliated anticoagulation clinics in the Salt Lake City region. Patients with atrial fibrillation that undergo a standard of care, clinically approved, left atrial appendage closure will be considered for study. All patients will be followed for 24 months, and will be assessed at the 3-, 6-, 12-, 18- and 24-months post-left atrial appendage closure as well as other visits deemed necessary for clinical care. All subjects will undergo protocol-specified laboratory tests and will complete 6 standard, validated questionnaires at each follow-up visit, except at the 3-month visit when only one questionnaire will be administered. A subset of patients (n=20), will receive a cranial MRI at baseline and 24-month visit. MRI PLUG Dementia Sub-Study: In addition to the above, 20 of the 60 subjects who are selected for participation in this sub-study will receive a cranial MRI at baseline and at the 2-year (24 months) follow-up visit.
