Effects of chest pain center construction on the treatment of acute ST-elevation myocardial infarction in basic-level hospitals / 中国基层医药

ABSTRACT

Objective:To investigate the effects of chest pain center construction in basic-level hospitals on treatment time and short-term prognosis in patients with acute ST-elevation myocardial infarction.Methods:A total of 162 patients with acute ST-elevation myocardial infarction who received percutaneous coronary intervention (PCI) in The First People's Hospital of Jiande between November 2014 and November 2018 were included in this study. Among them, 66 patients who received treatment in The First People's Hospital of Jiande between November 2014 and October 2016 were included in the control group. The remaining 96 patients who received treatment between November 2016 and November 2018 were included in the study group. The underlying diseases, PCI success rate, first medical contact-to-balloon time, door-to-balloon time, in-hospital mortality, incidence of heart failure on the next day of PCI, length of hospital stay, hospital medical cost were retrospectively analyzed.Results:There were no significant differences in underlying disease composition ratio and PCI success rate between the two groups (both P > 0.05). There were significant differences in first medical contact-to-balloon time [(185.2 ± 53.7) minutes vs. (108.6 ± 46.4) minutes, t = 6.128], door-to-balloon time [(121.5 ± 23.2) minutes vs. (68.7 ± 14.3) minutes, t = 7.341], length of hospital stay [(10.3 ± 3.5) days vs. (7.2 ± 2.8) days, t = 5.128], hospital medical cost [(43 582.0 ± 7 186.5) yuan vs. (35 479.0 ± 4 213.1) yuan, t = 8.361], in-hospital mortality [6.1% vs. 3.1%, χ2 = 4.784], the incidence of heart failure on the next day of PCI [13.6% vs. 4.2%, χ2 = 8.253] between the control and study groups (all P < 0.05). Conclusion:Establishment of a standardized chest pain center construction in basic-level hospital can greatly shorten the first medical contact-to-balloon time, door-to-balloon time and length of hospital stay, improve the cardiac function and prognosis of patients with myocardial infarction, and reduce medical cost.
