Objective To evaluate the role of a standardized chest pain center in reducing key time metrics in the emer-gency management of chest pain patients,including door-to-consultation time,test acquisition time,and total emergency depart-ment(ED)length of stay.Methods A pre-post comparative study was conducted involving 105 emergency chest pain patients admitted between January 2018 and December 2024(before and after chest pain center establishment).The pre-implementation group comprised of 45 patients,and the post-implementation group 60 patients.Key time metrics were compared between the two groups in terms of time to troponin result(from blood draw to result availability),time to first ECG(from first medical contact to ECG acquisition),total ED length of stay,and among ST-segment elevation myocardial infarction(STEMI)patients undergoing primary percutaneous coronary intervention(PCI),door-to-balloon(D2B)time and the rate of D2B time compliance(≤90 mi-nutes).Results After the chest pain center establishment,the post-implementation group showed significantly shorter times to troponin result,first ECG acquisition,and total ED stay(all P＜0.05).In the STEMI PCI subgroup,D2B time was significantly shorter in the post-implementation group(P＜0.001).Moreover,the D2B compliance rate was significantly higher in the post-implementation group(85.19％)compared to the pre-implementation group(9.09％)(P＜0.001).Conclusion The estab-lishment and operation of a standardized chest pain center significantly optimizes the emergency care process for chest pain pa-tients,effectively shortens multiple critical time intervals,and markedly improves treatment efficiency for STEMI patients requi-ring emergency PCI,thereby laying an important foundation for enhanced patient outcomes.
