目的 评价动机性访谈在促进经皮冠状动脉介入术(percutaneous coronary intervention,PCI)后患者低盐饮食中的效果.方法 采用便利取样法,在苏州某医院收集PCI后患者77例为研究对象,采用跨理论模型架构的评估方法,在常规健康教育基础上,采用动机访谈进行低盐饮食干预.结果 出院6个月后,患者高盐饮食改变阶段及盐分摄入量较干预前的差异有统计学意义(P＜0.05)；血压差异较干预前有明显统计学意义(P＜0.01).结论 动机性访谈通过激发患者的改变动机,可减少其每日盐分摄入量,帮助患者建立并维持低盐饮食行为,有效降低血压.%Objective To evaluate the effect of motivational interview(MI) on the compliance with low salt diet in patients after percutaneous coronary intervention (PCI). Method Seventy-seven patients with high salt diet after PCI were recruited by convenience sampling method. The patients received motivation interview based on the assessment of diet using trans-theoretical model of change(TTM). Result There were significant differences in the patients' diet change stages,salt intake and blood pressure before intervention and six months after discharge(P<0.05 or P<0.01). Conclusion MI can help the patients to establish and maintain low salt diet behavior by increasing patients' motivation, and can effectively reduce their blood pressure.
