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).

Cognitive Function assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)
時間枠:Visit 2 (Up to 2 hours)
|
The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a brief, individually administered test designed to evaluate neuropsychological status of adults, ages 20-89.
The 12 subtests measure attention, language, visuospatial/constructional abilities, and immediate and delayed memory.
|
Visit 2 (Up to 2 hours)
|
Cognitive Function assessed by the Controlled Oral Word Association (COWA) Test
時間枠:Visit 2 (Up to 2 hours)
|
The Controlled Oral Word Association (COWA) Test is a verbal fluency test that measures spontaneous production of words belonging to the same category or beginning with some designated letter.
The more words produced in the allotted time period the higher the score.

For Part 2, the respondent rapidly connects numbered circles in sequence, but alternates between pink and yellow.
The length of time to complete each trial is recorded, along with qualitative features of performance indicative of brain dysfunction, such as near-misses, prompts, number sequence errors, and color sequence errors.
