ObjectiveTo investigate the effect of chest pain center construction and routine diagnosis and treatment procedure on the efficacy of emergency percutaneous coronary intervention in patients with acute ST-segment elevation myocardial infarction(STEMI).

MethodsPatients with STEMI before and after the chest pain center construction were selected as control group(n=50) and observation group(n=56).The treatment time, incidence of heart failure and mortality during hospitalization, and left ventricular diameter, left ventricular ejection fraction, creatinine level and readmission rate three months after surgery were compared between the two groups.

ResultsThe first medical contact-to-balloon(FMC-to-B) time, door-to-balloon(D-to-B) time, hospitalization time, incidence of heart failure and mortality during hospitalization, and left ventricular ejection fraction before discharge in observation group were lower than those in control group(P < 0.05 to P < 0.01).After three months of follow-up, the left ventricular diameter and left ventricular ejection fraction in observation group were significantly improved compared with those in control group(P < 0.01), but there was no significant difference in creatinine level and readmission rate between the two groups(P>0.05).

ConclusionsChest pain center mode can significantly shorten the FMC-to-B time and D-to-B time in STEMI patients, and improve the prognosis of patients.
