Key result
Poor preoperative nutritional status is linked to over a 4-fold increase in cardiac surgery mortality.
Why the study?
The association of preoperative hormone and nutritional status with mortality after elective cardiac surgery was unclear.
Observational (n=252)
No
Hazard Ratio: 4.384 (95% CI 1.866–10.303)
p-value: p=0.001
Preoperative malnutrition indices were associated with post-cardiac surgery mortality; supports screening but leaves open whether optimization alters outcomes.

Tóth et al. (2022) conducted an observational in elective cardiac surgery (n=252). Poor preoperative nutritional status vs. Normal nutritional status was evaluated on overall mortality (AHR 4.384, 95% CI 1.866-10.303, p=0.001). Poor preoperative nutritional status (GNRI < 91) was associated with increased mortality after elective cardiac surgery (AHR 4.384; 95% CI 1.866-10.303; p=0.001).
