Abstract:
Objective:To explore the effect of continuous improvement of emergency procedures in different departments on reperfusion and prognosis of patients with acute ST segment elevation myocardial infarction after chest pain center certification.Methods:From March 2018 to July 2019, the clinical data of 206 patients with acute ST segment elevation myocardial infarction and percutaneous coronary intervention diagnosed in the chest pain center of the Third Affiliated Hospital of Anhui Medical University&Hefei First People′s Hospital were analyzed retrospectively.Ninety-eight patients admitted before certification were set as the control group, and 108 patients admitted after certification were set as the study group.The patients in the study group and the experimental group were compared in terms of the time from the onset to the initial medical contact, the time from the entrance to the implantation of balloon dilation, the time from the initial medical contact to the implantation of balloon dilation, the time of total ischemia and the incidence of major cardiovascular adverse events 30 days after percutaneous coronary intervention.Logistic regression analysis was used to analyze the influencing factors of major adverse cardiovascular events 30 days after operation.Results:Compared with the control group, the time from initial medical contact to implantation of balloon was (84.5 (73.0, 96.0) min), the time of total ischemia was (205.0(159.8, 307.0) min), the time from entrance to implantation of balloon was (72.5(58.3, 83.8) min) in the study group, which was (112.0(93.0, 132.5) min, 241.0(199.0, 329.0) min, 78.0(68.0, 96.5) min was significantly shorter than that of the control group, and the difference was statistically significant (all P<0.05). The time from the onset of disease to the initial medical contact in the study group was slightly shorter than that in the control group(124.5 (77.3, 201.0) min and 130.0 (76.3, 216.0) min), there was no significant difference ( P>0.05). Compared with the control group, the incidence of major cardiovascular adverse events in the study group was lower 30 days after operation (16.7%(18/108) and 28.6%(28/98)), the difference was statistically significant( P=0.040). According to the results of multivariate logistic regression analysis, Killip Ⅲ, Ⅳ ( OR 2.618, 95% CI1.244-5.509, P=0.011), the time from onset to initial medical contact>90 min ( OR 4.562, 95% CI 2.167-9.603, P<0.001), the time from entrance to implantation of balloon>60 min ( OR 2.227, 95% CI1.087-4.563, P=0.029) was an independent risk factor for major adverse cardiovascular events 30 days after operation. Conclusion:The continuous improvement of chest pain center process can promote the rational utilization of medical resources in the region, more effectively shorten the treatment time of myocardial infarction patients, and reduce the occurrence of major cardiovascular adverse events within 30 days after operation.
