Analysis of the predictive effect of two early warning scoring systems on cardiac arrest in patients with acute coronary syn-drome
Objective To explore the predictive effect of two early warning scoring systems on cardiac arrest in patients with acute cor-onary syndrome.Methods A retrospective case-control study was conducted to conveniently select 300 patients who were admitted to the e-mergency department of a hospital for treatment of acute coronary syndrome from December 2018 to December 2022 as the study subjects.Ac-cording to whether cardiac arrest occurred 24 hours after admission,they were divided into case group(158 cases)and control group(142 ca-ses).The vital signs of patients in the case group were collected at 30 min,1 h,2 h,4 h,8 h,16 h and 24 h before cardiac arrest,and were brought into the modified early warning score scale and the importance early warning score scale.In the control group,the time points with complete data within 24 hours were randomly selected to correspond to the case group,and the contents and methods of collection were the same as those of the case group.Results At each time point 30 min to 24 h before cardiac arrest,the scores of the two scales in the case group were significantly higher than those in the control group(P＜0.05).At 8 h before cardiac arrest,the area under the ROC curve of modi-fied early warning score scale was 0.642,which had a low predictive efficiency,and the area under the ROC curve of importance early warning score scale was 0.783,which had a medium predictive efficiency.Within 8 hours before cardiac arrest,the area under the ROC curve of the importance early warning score scale was＞0.7,and there was no statistically significant difference between each value(P＞0.05).And the im-portant early warning score scale had a good predictive effect on the occurrence of cardiac arrest in patients with various types of acute coro-nary syndrome.Conclusion The important early warning score has higher predictive effect than the modified early warning score,which can predict the occurrence of cardiac arrest 8 hours in advance,and has a good predictive effect on the occurrence of cardiac arrest in patients with various types of acute coronary syndrome.It is recommended for clinical application.
