Background/Aims: The purpose of this study was to compare changes in primary percutaneous coronary artery intervention (PCI) outcomes after starting the government-directed Busan-Ulsan Regional Cardiocerebrovascular Center Project. Methods: Patients with ST segment elevation myocardial infarction (STEMI) who visited the Busan-Ulsan Regional Cardiocerebrovascular Center from 1 June 2009 to 30 May 2011 were selected. Their medical records were retrospectively reviewed. Clinical and survival outcomes before and after starting the project were compared. Results: A total of 122 patients (mean age, 63 ± 13 years; male, 74%) with STEMI were selected for analysis. There were no significant differences in patients’ baseline characteristics. After starting the Busan-Ulsan Regional Cardiocerebrovascular Center Project, the door-to-balloon time decreased from 72 ± 30 to 59 ± 22 minutes (p = 0.011). The door-to-balloon time when the PCI team did not stay in the hospital also decreased from 80 ± 30 to 62 ± 12 minutes (p = 0.005). However, there was no significant change in the total ischemic time (339 ± 293 vs. 304 ± 287 minutes, p = 0.514), survival discharge rate (94% vs. 93%, p = 1.000), or 1-year survival rate (89% vs. 91%, p = 0.996). Conclusions: After starting the government-directed Busan?Ulsan Regional Cardiocerebrovascular Center Project, the door-to-balloon time was significantly reduced. However, the total ischemic time and short-term survival remained unchanged.
