Role of the chest pain center in treatment of patients with acute ST-elevated myocardial infarction

Objective 　To evaluate the role of establishment of the chest pain center in the treatment of patients with acute ST-elevated myocardial infarction (STEMI). Methods 　Referring to the international association of chest pain centers, the chest pain center was established in the hospital the authors served, and the corresponding management system and treatment process were worked out. A total of 576 patients with acute STEMI, admitted after the establishment of the chest pain center (May 2015 Mar. 2016), were recruited as the observation group, and 512 STEMI patients admitted before the establishment of the chest pain center ( Jan. -Dec. 2014) were enrolled as control group. Patients in observation group were treated in the chest pain center, and those in control group received conventional treatment. The general situation, basic diseases, the finishing time of the first ECG and the completed number of ECG within 10 minutes, the success rate of stent implantation in percutaneous coronary intervention (PCI), the time of door-to balloon expansion (D2B), the length of hospital stay and in-hospital mortality were compared between the two groups. Results 　No significant difference existed between the two groups in the species composition of diseases, age and sex. The average finishing time of the first ECG was shorter in observation group than in control group (P=0.001), the success rate of stent implantation in PCI was higher in observation group than in control group, but without statistical significance (P=0.222). The time of D2B and of hospital stay was shorter in observation group than in control group (P 0.05). Conclusion 　The establishment of the chest pain center may effectively shorten the rescue time for patients with STEMI, improve the efficiency of treatment and shorten the length of hospital stay, and is worthy of further clinical promotion.
