急性心肌梗死支架术后患者不同时期服药依从性及其影响因素的调查与分析

目的 ：观察急性心肌梗死支架术后患者院外服药依从性的变化趋势及不同时期依从性的影响因素分析。方法 ：采用方便抽样的方法,对首次发作急性心肌梗死并行支架植入术的患者126例进行术后1年的服药依从性跟踪调查。共对患者进行4次电话回访,即术后3、6、9、12个月。调查工具包括：患者的一般资料、服药依从性问卷、社会支持评定量表、Charlson合并症指数评分表等。结果 ：急性心肌梗死支架术后患者的院外服药依从性水平较低,且随着时间的推移呈明显下降趋势。不同时期影响患者依从性的因素中正向影响因素有社会支持、年龄、教育程度;负向影响因素有Charlson合并症指数、住址等。结论：急性心肌梗死支架术后患者的服药依从性情况不容乐观,应根据不同时期依从性的影响因素进行有针对性的干预,从而提高支架术后患者的服药依从性。

Investigation and analysis of medication adherence and influencing factors among Acute Myocardial Infarction patients with coronary stent implantation

Objective： To observe the change trend and status of medication adherence among patients with Acute Myocardial Infarction（AMI） after coronary stent implantation, and analyze the influencing factors in different periods. Methods： Totally 126 AMI patients with coronary stent implantation were conveniently sampled in this study. There were 4 times＇ telephone visit at 3, 6, 9 and 12 months after coronary stent implantation. The investigation tools included the medication adherence questionnaire, the Social Supports Rating Scale（SSRS）, and the Charlson comorbidity index. Results： The medication adherence level of the AMI patients with coronary stent implantation was relatively low, and it was obviously decreased over time. The positive factors of medication adherence were social support, age, and the education level; while the negative factors included the Charlson comorbidity index and non-local residence. Conclusion： The medication adherence status was not optimistic among AMI patients with coronary stent implantation. Interventions should be implemented according to the influencing factors in different periods to improve medical adherence of AMI patients with coronary stent implantation.
