In the medical management of acute myocardial infarction, the transport of patients and primary care provided by emergency medical technicians (EMTs) and paramedics are effective in reducing the mortality and disabilities. Therefore, the present study aimed to compare the outcomes of emergency medical services (EMS) vs. non-EMS transport of patients with ST-segment elevation myocardial infarction (STEMI) in southern Iran.
This is an analytical, cross-sectional study. The study population consisted of the individuals registered in Fasa Registry on Acute Myocardial Infarction (FaRMI) in the south of Iran. 2244 patients with STEMI were included in the study. Statistical analyses were performed using Chi-Square test and independent t-test at a significance level of P < 0.05 in SPSS 22.
Out of the 2244 patients with STEMI, 1552 (69.16%) were male and 672 patients (29.94%) were female. 934(41.62%) patients used EMS transport to the hospital, while 1310 (58.37%) patients used non-EMS transport to the hospital. A total of 169 patients with STEMI (7.26%) expired (out-of-hospital cardiac arrest); of them, 113 (66.86%) patients did not use EMS transport to the hospital. Successful cardiopulmonary resuscitation (CPR) was performed on 52 patients who used EMS transport. 27 patients also received an effective DC shock due to ventricular fibrillation (VF). Of the total number of patients, 49 had a stroke; among them, 37(75.51%) patients did not use EMS transport.
In the present study, the death rate in patients with acute myocardial infarction who used EMS transport was lower than those who used non-EMS transport. The health system managers and policymakers in the healthcare systems are recommended to take the necessary measures to increase public health awareness and knowledge about the use of EMS and consequently reduce the death rate and complications of acute myocardial infarction.
在急性心肌梗死的医疗管理中，患者的转运和由急救医疗技术员（EMT）和护理人员提供的初级护理在降低死亡率和残疾率方面是有效的。因此，本研究旨在比较伊朗南部的 ST 段抬高型心肌梗死（STEMI）患者使用急救医疗服务（EMS）和非 EMS 转运的结果。
这是一项分析性、横断面研究。研究人群包括伊朗南部 Fasa 急性心肌梗死注册中心（FaRMI）登记的个体。共有 2244 例 STEMI 患者纳入本研究。使用 Chi-Square 检验和独立 t 检验在 SPSS 22 中进行统计学分析，显著性水平为 P<0.05。
在 2244 例 STEMI 患者中，男性 1552 例（69.16%），女性 672 例（29.94%）。934 例（41.62%）患者使用 EMS 转运至医院，而 1310 例（58.37%）患者使用非 EMS 转运至医院。共有 169 例 STEMI 患者（7.26%）死亡（院外心脏骤停）；其中，113 例（66.86%）患者未使用 EMS 转运至医院。使用 EMS 转运的患者中有 52 例成功进行了心肺复苏（CPR）。27 例因室颤（VF）还接受了有效的 DC 电击。在所有患者中，有 49 例发生中风；其中，37 例（75.51%）患者未使用 EMS 转运。
在本研究中，使用 EMS 转运的急性心肌梗死患者死亡率低于使用非 EMS 转运的患者。建议卫生系统管理者和卫生政策制定者采取必要措施，提高公众对 EMS 使用的健康意识和知识，从而降低急性心肌梗死的死亡率和并发症。
