Rethinking Preoperative Risk Evaluation: How Well Does EuroSCORE II Predict Long-Term Mortality After Cardiac...

Area of Science:

• Cardiology
• Cardiac Surgery
• Medical Statistics

Background:

• The EuroSCORE II is a standard tool for predicting short-term mortality in cardiac surgery.
• Limited data exist on its long-term predictive capabilities.

Purpose of the Study:

• To assess the association between EuroSCORE II and one-year and long-term mortality.
• To evaluate EuroSCORE II's utility as a long-term prognostic indicator in major cardiac surgery.

Main Methods:

• Retrospective cohort study of 2179 patients undergoing cardiac surgery with cardiopulmonary bypass (2017-2021).
• Data from Salzburg Intensive Care database and Statistik Austria.
• Analysis included Kaplan-Meier, Cox regression, and ROC analysis.

Main Results:

• EuroSCORE II was significantly higher in patients with one-year and long-term mortality.
• Median EuroSCORE II was 2.2 for survivors vs. 7.0 for one-year non-survivors.
• EuroSCORE II demonstrated good discriminative ability for one-year mortality (AUC 0.773).

Conclusions:

• EuroSCORE II is significantly associated with long-term mortality after major cardiac surgery.
• The scoring system shows good discriminatory performance for long-term outcomes.
• Findings support EuroSCORE II's utility as a long-term prognostic indicator.
