Clinical observation of evidence-based nursing model in acute myocardial infarction patients in CCU
循证护理模式用于CCU急性心梗患者的临床观察

摘要

目的 探讨循证护理模式用于冠心病监护病房（CCU）中急性心肌梗死患者的作用。方法 研究共计选择100例急性心肌梗死患者作为研究病例，均源自本医院（2025年1月至2026年1月），患者需分组（随机数字表法），分为对照组（50例），采用常规护理模式；观察组（50例），循证护理模式。通过对照研究评估两组患者护理后时间指标、情绪状态、再梗发生率与30天内心源性死亡率、不良事件发生率。结果 与对照组相比较，观察组患者的住院时间和再灌注治疗时间显著更短（P＜0.05）；护理前两组焦虑自评量表（SAS）与抑郁自评量表（SDS）评分十分接近（P＞0.05），护理后，两组数据拉开差距，观察低于对照组（P＜0.05）；观察组的再梗发生率与30天内心源性死亡率显著低于对照组（P＜0.05）；观察组患者经护理后的不良事件发生情况改善良好，显著更低（P＜0.05）。结论 针对CCU急性心肌梗死患者采用循证护理模式能够有效缩短其住院时间和再灌注治疗时间，加强患者情绪状态，降低再梗发生率与30天内心源性死亡率，同时减少住院期间的不良事件发生率，值得临床推广应用。

Abstract

Objective To investigate the efficacy of evidence-based nursing care in patients with acute myocardial infarction (AMI) admitted to the Cardiac Care Unit (CCU).
Methods A total of 100 AMI patients were enrolled as study subjects, all from our hospital (January 2025 to January 2026). Patients were randomly assigned to either a control group (n=50) receiving conventional nursing care or an observation group (n=50) receiving evidence-based nursing care. Post-intervention outcomes were evaluated including hospitalization duration, reperfusion therapy time, emotional status, reinfarction rate, 30-day cardiac mortality rate, and adverse event incidence.
Results Compared with the control group, the observation group exhibited significantly shorter hospitalization duration and reperfusion therapy time (P<0.05). Pre-nursing Self‑Rating Anxiety Scale (SAS) and Self‑Rating Depression Scale (SDS) scores were similar between groups (P>0.05), but post-intervention differences became significant, with the observation group showing lower scores than the control group (P<0.05). The observation group also demonstrated significantly lower reinfarction rates and 30-day cardiac mortality rates (P<0.05), along with markedly reduced adverse event incidence after nursing intervention (P<0.05).
Conclusion   Implementation of evidence-based nursing care for AMI patients in the CCU effectively shortens hospitalization and reperfusion therapy durations, improves emotional well-being, reduces reinfarction and 30-day cardiac mortality rates, and decreases adverse event rates during hospitalization, making it worthy of clinical adoption.
