Abstract:Objective To observe the impacts of the establishment of chest pain center (CPC) on emergency percutaneous coronary intervention (PCI) related indicators including door to balloon (D2B) time, D2B standard-reaching rate, time from taking blood to troponin report, time from first medical contact (FMC) to the first ECG record and in-hospital outcomes in patients with acute ST-elevation myocardial infarction (STEMI) undergoing primary PCI. Methods A total of 104 STEMI patients 9 months before and after CPC establishment were selected as research objects. The patients were divided into the group before CPC establishment (green channel group, n=45) and group after CPC establishment (CPC group, n=59). The D2B time, incidence of heart failure on the next day of PCI and in-hospital mortality were compared between two groups. Results Compared with pre-establishment of CPC, D2B time decreased significantly ［(90.5±39.0) min vs (148.9±67.9) min, P<0.01］, and D2B standard-reaching rate increased significantly (59.3% vs 22.2%, P<0.01) after CPC establishment.Compared with pre-establishment of CPC, the incidence of heart failure on the next day of PCI decreased slightly (11.9% vs 16.0%, P>0.05) , and in-hospital mortality increased slightly (8.5% vs 0, P>0.05) after CPC establishment. The time from taking blood to troponin report and the time from FMC to the first ECG record monthly declined and reached the CPC certification standard after CPC establishment. Conclusion CPC establishment can obviously shorten D2B time, raise D2B standard-reaching rate and improve cardiac function for STEMI undergoing emergency PCI.
