RESUMO
Objective To investigate the impact of the regional cooperative chest pain center (CPC) on therapeutic time and short term outcome after primary percutaneous coronary intervention (PCI) of patients with ST segment elevated myocardial infarction.Methods 372 patients with ST segment elevated myocardial infarction were enrolled in the study who had received were operated primary PCI 18 months before and after the regional cooperative CPC was set up.There were 156 patients in the green channel group before the setup of CPC and 216 patients in the CPC group.Total ischemia time,first medical contact (FMC) time,FML-to-balloon (FMC2B) time,door-to-balloon (D2B) time,hospital mortality rates,cardiac failure rates on the next day after PCI,length of CCU stays and hospital stays were compared between the two groups.Results Compared to the green channel group,total ischemia time[(281.0±102.7)min vs.(365.2±115.6)min,P＜0.05],FMC time [(174.3±97.5) min vs.(225.4±104.6) min,P＜0.05],FMC2B time [(106.7±61.2) min vs.(139.8±75.7) min,P＜0.05] and D2B time [(75.2±45.4) min vs.(102.4±53.7) min,P＜0.05] of the CPC group were significant shorter.The rates of reaching the standard of FMC2B time (70.83％ vs.34.62％,P＜0.001) and D2B time (75.93％ vs.40.38％,P＜0.001)were significantly higher in the CPC group.Cardiac failure rates on the next day after PCI was lower in the CPC group (14.35％ vs.23.72％,P=0.021),and CCU stays was shorter [(64.3±13.72)h vs.(92.6±15.65)h,P=0.043].Conclusions Establishment of a standardized regional cooperative CPC requires combination and consideration of the characteristics of local resources FMC2B time and D2B time of STEMI patients can be shorten by a standardized CPC lending to further shortening of total ischemia time and improvement in cardiac function.
