简介:【摘 要】目的: 分析心肌梗死患者介入治疗后实施Ⅰ期心脏康复护理对患者心理状态的影响。 方法: 本文研究初始时间为 2018 年 4 月,结束时间为 2019 年 8 月,共选择 96 例心肌梗死介入治疗患者。随机分为两组,对参照组患者予以一般护理,对实验组患者予以Ⅰ期心脏康复护理。分析两组患者的临床护理效果。 结果: 参照组患者 SDS 评分、 SAS 评分与实验组比较均显著更高, P<0.05 ;参照组患者左心室收缩末期内径与实验组比较显著更高, P<0.05 ;参照组患者左心室射血分数与实验组比较显著更低, P<0.05 。 结论: 针对心肌梗死介入治疗患者实施 Ⅰ期心脏康复护理,有利于改善患者心功能,缓解不良情绪,具有较高应用价值,值得推广。
