Evaluation of APACHE II Score and QT Interval Dispersion for the Prognosis of Critical Cardiovascular Diseases

摘要

Introduction: This pilot study evaluated the APACHE II Score and QT Interval Dispersion for the Prognosis of Critical Cardiovascular Diseases. Materials and methods:A total of 217 Critically ill patients with cardiovascular disease were Selected in the Capital Medical University Xuanwu Hospital Cardiology CCU from January 2016 to January 2017. Patients were divided into death group and survival group according to the their survival situation. APACHE II Score and QT Interval Dispersion of the patients entering the CCU were recorded separately. Results:The APACHE II score and QTd value in death group were significantly higher than those of survival group (P <0.05). The higher the APACHE II score and the QTd value, the higher the mortality rate, and the differences between the groups were statistically significant (p <0.05). There was a statistically significant difference between the combined score, the APACHE II score and the QTd score (P <0.05). AUC of the combined score was greater than APACHE II score. Conclusion: The combined score, APACHE II score and QTd score were significantly higher in the death group. Combined score and APACHE II score were more accurate than QT dispersion to predict the mortality of critically ill patients with cardiovascular disease. The combined score was slightly higher than the APACHE II score to predict accuracy of critical cardiovascular disease. And APACHE II score in the specificity slightly stronger than the combined score.
