Comparative analysis of the curative effect and prognosis of emergency percutaneous coronary intervention(PCI) and elective PCI in patients with acute ST-segment elevation myocardial infarction (ASTEMI)
对比分析急性ST段抬高型心肌梗死（ASTEMI）患者开展急诊经皮冠状动脉介入（PCI）治疗与择期PCI治疗的疗效及患者预后情况

摘要

目的 对比急性ST段抬高型心肌梗死（ASTEMI）患者接受急诊经皮冠状动脉介入治疗（PCI）以及择期接受PCI治疗的效果，并对比不同时机治疗对预后的影响。方法 本次纳入对象均为本院急诊收治并经过检查确诊为ASTEMI患者，患者发病日期在2020年7月－2021年12月之间。综合考虑疾病情况并征求患者家属意见后，接受相应治疗。依据治疗方案不同进行分组。将发病未超过12h，选择接受急诊PCI手术治疗患者50例纳入观察组。另外将接受常规治疗预防心室重构及相关并发症后住院择期接受PCI手术患者50例纳入对照组。对比不同时机接受介入治疗者手术效果及预后情况差异。结果 接受急诊PCI治疗患者，在院内及院外心血管不良事件发生率明显降低，住院时间相对较短(P<0.05)。结论 ASTEMI患者确诊后，接受急诊PCI治疗，保证手术效果改善心功能同时，可确切降低近期及远期不良心血管事件发生率。

Abstract

Objective To compare and analyze the efficacy of elective or emergency PCI in patients with acute ST-segment elevation myocardial infarction (ASTEMI). and to compare the effects of different timing of treatment on prognosis.
Methods The included subjects were all patients admitted to the emergency department of our hospital and confirmed to be ASTEMI after examination. The onset date of the patients was between July 2020 and December 2021. After comprehensive consideration of the disease conditions and consultation with the patient's family members, the patients received corresponding treatment. Grouped according to different treatment regimens. A total of 50 patients who received emergency PCI surgery within 12 hours of onset were included in the observation group. In addition, 50 patients hospitalized for elective PCI after receiving conventional treatment to prevent ventricular remodeling and related complications were included in the control group.The differences in surgical outcomes and prognosis of patients receiving interventional therapy at different times were compared.
Results The incidence of cardiovascular adverse events in patients receiving emergency PCI was significantly reduced in hospital and out of hospital, and the hospital stay was relatively short(P<0.05).
Conclusion   After ASTEMI patients are diagnosed, they will receive emergency PCI treatment to ensure the surgical effect and improve cardiac function, which can definitely reduce the incidence of short-term and long-term adverse cardiovascular events.
