Brief Summary:

The purpose of the study is to examine if blood flow in the brain before coronary artery bypass graft surgery has an effect on depression after surgery.

The main hypothesis of the study states that pre-surgical blood flow in the brain will be an independent risk factor for depression after surgery after adjusting for other risk factors such as gender, pre-CABG depression, social support, medical comorbidity burden, socioeconomic status, and neuroticism.

No treatment.

Primary Outcome Measures :
  1. Pre-surgical intracranial atherosclerosis as measured by transcranial doppler ultrasound relative to depressive symptoms post-surgically as measured by DISH. [ Time Frame: 12 months ]

Secondary Outcome Measures :
  1. Examine neurocognitive function relative to post-CABG depression through a series of neurocognitive tests. [ Time Frame: 12 months ]
    Neurocognitive tests are aimed at evaluating memory, processing speed, and global cognition.
