【摘 要】目的：观察冠心病合并心律失常采取稳心颗粒与美托治尔联合治疗的疗效及安全性。方法：本次试验研究对象是我院收治的80例冠心病合并心律失常患者，研究时段为2019年1月至2020年1月，按照患者就诊顺序将其分为两组，各40例，观察组与对照组分别采取稳心颗粒联合美托治尔治疗与常规治疗，对比组间治疗效果。结果：未治疗时，组间左室舒张末期内径、左室收缩末期内径、左室射血分数对比，无明显差异(P>0.05);经治疗，观察组比对照组左室舒张末期内径、左室收缩末期内径更低，左室射血分数跟高，数据差异显著(P<0.05)。结论：冠心病合并心律失常采取稳心颗粒与美托治尔联合治疗，能够稳定患者心功能指标，改善血液流变学，降低不良反应发生率，值得临床实践。
