Performance of EuroSCORE II in patients who have undergone heart valve surgery: a multicentre study in a Chinese population
Key result
EuroSCORE II demonstrated better discrimination than the logistic EuroSCORE for predicting in-hospital mortality in Chinese patients undergoing heart valve surgery (C-statistic 0.72 vs 0.67).
Why the study?
Does EuroSCORE II improve in-hospital mortality prediction compared to logistic EuroSCORE in Chinese patients undergoing heart valve surgery?

Implication
May support EuroSCORE II preference in Chinese valve surgery; extends validation but leaves calibration and broader use open.

Main Result
Effect estimate: C-statistic 0.72 (95% CI 0.69-0.75)
Absolute Event Rate: 0.72% vs 0.67%
EuroSCORE II provides better discrimination than the original logistic EuroSCORE for predicting in-hospital mortality in Chinese patients undergoing heart valve surgery, though calibration remains suboptimal.
Cite This Study
Wang et al. (2013) conducted an observational in Heart valve surgery (n=11,170). EuroSCORE II vs. Logistic EuroSCORE was evaluated on Model discrimination (C-statistic) for in-hospital mortality (C-statistic 0.72, 95% CI 0.69-0.75). EuroSCORE II demonstrated better discrimination than the logistic EuroSCORE for predicting in-hospital mortality in Chinese patients undergoing heart valve surgery (C-statistic 0.72 vs 0.67).
