简要总结
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.
详细描述
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.

主要结局
Structural White Matter
时间窗: 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.
