Predictive Role of Preoperative Nutritional Status on Early Postoperative Outcomes in Different-Aged Patients Undergoing Heart Valve Surgery

In patients who undergo heart valve surgery, early postoperative outcomes can be influenced by nutritional status before the surgery. In the young-adult group, NRI <99 and NRI <97 effectively could predict prolonged intensive care unit stay and 30-day mortality, respectively.
Study context
- Population
- Patients undergoing heart valve surgery, October 2016–December 2020, in 3 age subgroups (young 18–44, middle-aged 45–59, older ≥60 years)
- Participants
- 3,905 patients
- Exposure
- Preoperative nutritional status across age subgroups
- Outcome
- Prolonged ICU stay, young adults
Methodological detailssingle-centre, ROC curve analysis, logistic regression
