    AbstractStandardized construction of China Chest Pain Center improves outcomes in patients with acute ST-segment elevation myocardial infarction (STEMI). A total 778 patients with a definite diagnosis of STEMI who underwent percutaneous coronary intervention (PCI) in our hospital from March 2017 to November 2022 were selected. Among them, 194 patients admitted from March 2017 to December 2019 were included as the pre-continuous improvement period (control group), and 584 patients admitted from January 2020 to November 2022 were included as the continuous improvement period (study group). Major quality control indicators were compared between the 2 groups. In continuous improvement period, the time of electrocardiograph (ECG) diagnosis, time of dual antiplatelet drug administration, troponin I return time, catheter activation time, and door to wire (D2W) were all significantly shorter than those in the pre-continuous improvement period (P < .05). The reperfusion rate of patients in the continuous improvement period was 98.12%, which was significantly higher than that in the pre-continuous improvement period (92.78%; P < .001). The mortality rate of STEMI patients in continuous improvement period was 3.42%, lower than 4.64% in the pre-continuous improvement period with no statistical difference (P = .439). Age, previous history of coronary artery disease, and high Killip class (Killip III-IV) were derived as independent risk factors for death by logistic regression analysis (OR＞1, P < .05). Continuous improvement of the chest pain center can effectively shorten the treatment time of STEMI patients, improve the reperfusion rate, and improve myocardial blood supply by restoring TIMI blood flow as early as possible.Copyright © 2024 the Author(s).
