About this study

Purpose The purpose of this study is to determine whether filtering out blue light at nighttime reduces post-surgical inflammation and/or moderates cognitive decline and mood and sleep alterations in patients undergoing elective CABG, AVR, MVR, CABG AVR, CABG MVR, or SAH surgery. If manipulating nighttime light in hospital rooms improves patient outcomes, then it would be a relatively easy and inexpensive innovation that could reduce post-surgical complications and save millions of dollars per year in health care costs by shortening the length of hospital stays and reducing morbidity. The investigators aim to determine the relationship between inflammation and cognitive dysfunction after cardiac surgery.
