Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults undergoing elective CABG, AVR, MVR, CABG AVR, CABG MVR, or SAH surgeries without a history of psychiatric disorders or organ failure.

Probably not a fit

Patients with cognitive deficits, psychiatric disorders, or significant organ failure may not benefit from this study.

What this trial studies

This study investigates whether filtering out blue light at night can reduce inflammation and improve cognitive function, mood, and sleep in patients recovering from elective heart surgeries such as CABG, AVR, and MVR. The approach involves using blue light-blocking goggles during the night to create a more conducive recovery environment. The hypothesis is based on previous animal studies suggesting that exposure to blue light can exacerbate inflammation and cognitive decline post-surgery. If successful, this intervention could lead to shorter hospital stays and improved patient outcomes.

Why it matters

Potential benefit: If successful, this could lead to reduced post-surgical complications and improved recovery for heart surgery patients.

How similar studies have gone: While the approach is novel in the context of cardiac surgery, similar studies in other fields have shown promise in reducing inflammation and improving recovery through light manipulation.
