120急救转运系统对急性ST段抬高型心肌梗死患者的救治意义

Significance of emergency transport system in treatment of patients with acute st-segment elevation myocardial infarction

目的分析急性ST段抬高型心肌梗死救治过程中120急救转运系统的应用价值。方法选取三门峡市中心医院2015年8月-2018年8月行PCI(经皮冠状动脉介入)的STEMI(ST段抬高型心肌梗死)患者100例,按入院方式作为依据,将自行入院的50例患者作为对照组,将120急救转运系统入院的50例患者作为观察组,对比两组再灌注时间、心脏超声随访指标。结果观察组首次医疗接触时间(first medical contact,FMC)至球囊扩张时间短于120 min的患者构成比为30%(15/50),低于对照组的46%(23/50),差异有统计学意义(χ2=10.2686,P<0.05);观察组患者FMC至球囊扩张时间为(92.25±1.58)min,明显短于对照组的(135.63±73.15)min,住院时间为(7.15±0.25)d,短于对照组的(10.25±1.96)d,差异有统计学意义(t=12.6326、9.6326,P<0.05);两组患者术后1周左心室舒张末容积(LVEDV)、左心室收缩末容积(LVESV)与左心射血分数(LVEF)指标对比差异无统计学意义(P>0.05);两组术后6个月LVEF对比差异有统计学意义(t=8.5257,P<0.05)。结论急性ST段抬高型心肌梗死救治过程中120急救转运系统的应用价值理想,值得推广。

Objective To analyze the application value of 120 emergency transport system in the treatment of acute st-segment elevation myocardial infarction. Methods From August 2015 to August 2018 conducting PCI(percutaneous coronary intervention) in STEMI patients with st-elevation myocardial infarction of 100 cases in hospital, self-come patients 50 cases as control group, the 120 emergency transport system 50 cases of hospitalized patients as observation group, compared two groups of reperfusion time, follow-up echocardiographic index.Results In the observation group, the proportion of patients whose first medical contact(FMC) time to balloon dilation shorter than 120 min was 30%(15/50), lower than that of the control group 46%(23/50), with statistically significant difference(χ~2=10.2686, P<0.05). The duration of FMC to balloon dilation in the observation group was(92.25±1.58) min, which was significantly shorter than that of the control group(135.63±73.15) min, and the length of hospitalization was(7.15±0.25) d, which was shorter than that of the control group(10.25±1.96) d, with statistically significant differences(t=12.6326, 9.6326, P<0.05). There was no statistically significant difference in left ventricular end-diastolic volume(LVEDV), left ventricular end-systolic volume(LVESV) and left ventricular ejection fraction(LVEF) at 1 week after surgery between the two groups(P>0.05). There were statistically significant differences in LVEF 6 months after operation between the two groups(t=8.5257,P<0.05). Conclusion The application value of 120 emergency transport system in the treatment of acute st-segment elevation myocardial infarction is ideal and worth promoting.
