[Study on the efficiency of the European System for Cardiac Operative Risk Evaluation (EuroSCORE) in predicting in-hospital mortality of the patients with percutaneous coronary intervention].

Objective: To investigate the efficiency of European System for Cardiac Operative Risk Evaluation (EuroSCORE) in predicting in-hospital mortality for the patients after percutaneous coronary intervention (PCI).

Methods: Retrospective analysis was conducted on the patients who had undergone PCI in our hospital since year 2005 to 2007. We used both cumulative EuroSCORE score and logistic EuroSCORE to predict the in-hospital morality and to analyze the correlation between the predicted mortality and the actual mortality.

Results: According to the additive EuroSCORE, we divided the patients into three groups, the additive EuroSCORE 0-2 were divided into low-risk group, 3-5 were divided into mid-risk group and ≥ 6 into high-risk group. The actual in-hospital mortality rates were 0%, 0.47% and 6.09% respectively. The EuroSCORE model demonstrated an overall relation between the EuroSCORE ranking and the incidence of in-hospital mortality (P<0.001). Results from the multivariable logistic regression analysis showed that the EuroSCORE was an independent in-hospital mortality predictor (P<0.01).

Conclusion: The EuroSCORE risk model and the in-hospital mortality were significantly correlated, indicating that the model was a promising method for predicting the in-hospital mortality of PCI patients.
