Abstract: Objective To explore trends of the National Early Warning Scores (NEWS) 24h prior to in-hospital cardiac arrest (IHCA) for patients with acute coronary syndromes (ACS). Methods We conducted a retrospective case-control study in 3 tertiary hospitals in Fujian Province,patients with ACS who experienced cardiac arrest were in the case group. We randomly selected patients with ACS who had not experienced cardiac arrest as the control group. The NEWS was calculated at 24h,16h,8h,1h and 0.5h before cardiac arrest and the trends were analyzed. Results The NEWS were significantly different between the case group and the control group at 24h,16h, 8h, 1h and 0.5h before cardiac arrest, the scores in the case group were higher than those in the control group, and the trend was continuingly rising (P<0.001). The proportion of high-risk NEWS group was enlarged before cardiac arrest (from 24h to 0.5 h,NEWS increased from 11.6% to 36.62), and the proportion of low-risk NEWS group was smaller (from 24h to 0.5h,NEWS decreased from 67.7% to 21.4%). From 24h to 0.5h prior to cardiac arrest, compared to low-risk group, the incidence of cardiac arrest of high-risk group was increased from 7.00 times to 56.57 times. Conclusion The NEWS can properly predict cardiac arrest among patients with ACS, and can better identify high-risk patients.
