A Comparison of Magnetic Resonance Imaging in Persons With Heart Failure to Health, Aged Matched Controls (MIND-HF)

20. září 2017 aktualizováno: Rebecca Gary, Emory University

A Comparison of Magnetic Resonance Imaging in Persons With Heart Failure to Health, Aged Matched Controls (MIND-HF)

The purpose of this study is to examine the relation between the structural brain changes associated with heart failure, neurocognitive performance, and how these changes impact self-care behaviors.

Přehled studie

Detailní popis

The purpose of this study is use neuroimaging techniques to better understand the underlying structural brain changes and physiological mechanisms that guide the thinking and decision making processes required for people with heart failure. The study will compare how the underlying brain structures and circulation are similar to or different in persons with heart failure to healthy, aged matched controls using special neuroimaging procedures.

Intervence / Léčba
Participants with Heart Failure
Participants with heart failure will complete neurocognitive tests and undergo magnetic resonance imaging (MRI).

Magnetic Resonance Imaging (MR) will be acquired on a research dedicated Siemens 3Tesla TIM TRIO MRI scanner with a 32-channel head coil.The MRI scanning protocol will have scans to measure voxelwise and whole-brain measures of grey matter (GM) volumes through a high resolution T1-weighted (T1W) multi-echo magnetization prepared gradient echo (MEMPRAGE) anatomic scan.

Total time in scanner will be approximately 53 minutes.

Cognitive function will be assessed using several batteries; the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Controlled Oral Word Association Test (COWA), the Color Trails 1 & 2, the WAIS-III Digit Span and Letter Number Sequence test, the Stroop Test, and the California Computerized Assessment Package Reaction Time test (CALCAP).
