Sleep problems before heart surgery may affect recovery outcomes

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational study at Fuwai Hospital in Beijing that collects perioperative blood and fecal samples from adults undergoing elective cardiac surgery to examine how preoperative sleep disorders relate to postoperative outcomes. Researchers will record outcomes such as delirium within 7 days, cognitive function scores, ventilation time, and lengths of ICU and hospital stays. The goal is to identify metabolic and biomarker patterns that connect sleep problems before surgery with adverse postoperative results. No interventions are performed; data will be analyzed to understand potential mechanisms and markers. The study will help clarify whether sleep health before surgery influences recovery trajectories in cardiac patients.
