Many studies have shown that those with coronary artery disease (CAD) have a more rapid decline in memory than expected and that they are at an increased risk of developing dementia. It is not understood how memory decline is linked to CAD; however, it has recently been discovered that certain byproducts of fat breakdown involved in the development of CAD, called ceramides, can harm brain cells. In the present study the investigators will recruit 129 CAD patients from a cardiac rehabilitation facility and measure memory performance and blood ceramide concentrations at baseline, 6 months and 12 months. The investigators will also measure important blood messengers of inflammation and assess whether they are associated with ceramide production. In addition, relationships between ceramides and other aspects of brain function, such as thinking speed and the ability to plan and sort information will be explored.

Primary Outcome Measures:
  • Change in Verbal memory [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Verbal memory will be assessed using the California Verbal Learning Test, 2nd Edition (CVLT-II)

Secondary Outcome Measures:
  • Neuropsychiatric battery [ Time Frame: Baseline, 3 months, 6 months ] [ Designated as safety issue: No ]
    The neuropsychiatric assessment battery recommended by NINDS-CSN harmonized standards will be conducted

  • Montreal Cognitive Assessment (MoCA) [ Time Frame: Baseline, 3 months, 6 months ] [ Designated as safety issue: No ]
    The MoCA will be used to assess global cognition

Biospecimen Retention:   Samples With DNA

Whole blood for ApoE4 genotyping

Estimated Enrollment: 129
Study Start Date: November 2011
Estimated Primary Completion Date: June 2014 (Final data collection date for primary outcome measure)
