Brief Summary

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, 3 months and 6 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.
