Hypothesis
Lower GNRI values would be correlated with poorer clinical outcomes in patients undergoing coronary revascularization.
Conclusion
Patients with lower GNRI had higher 28-day mortality, greater risk of AKI, and longer hospital stays.
Supporting Evidence
- Lower GNRI scores were associated with higher 28-day mortality.
- Patients with lower GNRI had a greater incidence of acute kidney injury (AKI).
- Lower GNRI was linked to longer hospital stays.
Takeaway
If older patients don't get enough nutrition, they might have a harder time after heart surgery and could stay in the hospital longer.
Methodology
Patients with coronary revascularization were screened from the MIMIC-IV database, and GNRI was calculated to assess nutritional status and its impact on outcomes.
Potential Biases
Potential confounding variables may affect the interpretation of treatment effects.
Limitations
The study's observational design limits control over confounding variables and generalizability due to data being sourced from a single medical center.
Participant Demographics
The study included adult patients undergoing coronary revascularization, with a mean age of 70.7 years.
