Brief summary
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.
Detailed description
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.
Interventions
OTHERBrain Imaging (Neuroimaging)
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.
OTHERCognitive Function Assessment
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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Structural White Matter | Visit 1 (Up to 2 hours) | Diffusion tensor imaging (DTI) and myelin water imaging (MWI) will be used to compare brain structural white matter between participants with heart failure and healthy controls. This will be obtained via magnetic resonance imaging (MRI) techniques. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Global Cerebral Blood Flow (CBF) | Visit 1 (Up to 2 hours) | Arterial spin labeling (ASL) based magnetic resonance (MR) perfusion imaging will evaluate global cerebral blood flow (CBF). This will be obtained via magnetic resonance imaging (MRI) techniques. |
| Regional Cerebral Blood Flow (CBF) | Visit 1 (Up to 2 hours) | Arterial spin labeling (ASL) based magnetic resonance (MR) perfusion imaging will evaluate regional cerebral blood flow (CBF). This will be obtained via magnetic resonance imaging (MRI) techniques. |
| Structural Grey Matter | Visit 1 (Up to 2 hours) | Voxel-based morphometry (VBM) of T1-weighted (T1w) high-resolution magnetic resonance imaging MRI anatomics will be used to measure brain structural white matter. |
| Cognitive Function assessed by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) | 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. |
| Cognitive Function assessed by the Controlled Oral Word Association (COWA) Test | 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. |
| Cognitive Function assessed by the Color Trails Test | Visit 2 (Up to 2 hours) | The Color Trails Test measures sustained attention and sequencing. For Part 1, the respondent uses a pencil to rapidly connect circles numbered 1-25 in sequence. 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. |
| Functional Connectivity | Visit 1 (Up to 2 hours) | Functional connectivity that regulates neurocognitive functions will be assessed by blood oxygen level dependent resting state functional MRI (rsFMRI).This will be obtained via magnetic resonance imaging (MRI) techniques. |
| Cognitive Function assessed by the Wechsler Adult Intelligence Scale-III (WAIS-III) Letter Number Sequence Test | Visit 2 (Up to 2 hours) | During the Wechsler Adult Intelligence Scale-III (WAIS-III) Letter Number Sequence Test, participants will be presented with combinations of letters and numbers, (two to nine letter-number combinations). Participants will be asked to repeat each series by, first, repeating the numbers in ascending order, then the letters in alphabetical order. The test measures working memory or the ability to simultaneously recall and organize stimuli of different and similar types |
| Cognitive Function assessed by the Stroop Test | Visit 2 (Up to 2 hours) | The Stroop Test measure a person's selective attention capacity and skills, as well as their processing speed ability.It is used to examine a person's executive processing abilities. The Stroop Test during brain imaging studies is used to investigate regions of the brain that are involved in planning, decision-making, and managing real-world interference |
