Association Between Preoperative Red Cell Distribution Width-to-hemoglobin Concentration Ratio and Postoperative Mortality in Adult Cardiac Surgery Patients
Authors' conclusion
Preoperative RHR is a biomarker associated with 30-day and 1-year postoperative mortality as well as postoperative complications in patients undergoing scheduled cardiac surgery.
Study context
- Population
- Adults (≥20 years) undergoing elective cardiac surgery under GA, January 1, 2014 to September 30, 2020analysed
- Participants
- 293 adults
- Exposure
- High vs low preoperative RDW-to-hemoglobin concentration ratio
- Outcome
- Postoperative mortality
- Follow-up
- 30-day and 1-year
Methodological detailsData retrospectively collected from electronic medical records and anesthetic charts
- Data retrospectively collected from electronic medical records and anesthetic charts
Main finding
As reported in the abstract
