目的 探讨行为干预联合针对性宣教对心肌梗死PCI术患者服药依从性、认知程度及再狭窄发生率的影响。方法 选 取我院2014年9月至2015年7月期间收治的经确诊为心肌梗死的患者92例，随机分为观察组和对照组，每组46例，对 照组给予术前准备、PCI术后及急性心肌梗死的常规护理，观察组在对照组基础上进行行为干预联合针对性宣教护 理，比较两组服药依从性、认知程度及再狭窄发生率。结果 两组12个月随访成功率均为100%。出院后3个月服药依 从性比较无明显差异（P＞0.05）；观察组出院后6个月、12个月服药依从性明显高于对照组(P＜0.05)。观察组病 情认知程度评分显著高于对照组，再狭窄发生率4.35%明显低于对照组17.39%(P＜0.05)。结论 行为干预联合针对 性宣教护理可明显提高心肌梗死PCI术患者服药依从性、认知程度，降低再狭窄发生率。

Objective To study the effect of behavioral intervention combined with targeted education on medication compliance, cognitive degree and incidence of restenosis in patients with myocardial infarction after PCI operation. Methods From Sep. 2014 to Jul. 2015, a total of 92 patients with myocardial infarction in our hospital were taken as the clinical research objects, and they were randomly divided into observation group (46 cases) and control group (46 cases). Both groups were given conventional nursing, besides, the observation group accepted additional behavioral intervention combined with targeted education in order to compare their medication compliance, cognitive degree and incidence of restenosis. Results After 12 months follow-up, the success rates in both groups were 100%. 3 months after discharge, there was no significant difference in medication compliance (P>0.05); 6 and 12 months after discharge, the medication compliance in the observation group was significantly higher than that in the control group (P<0.05). The cognitive degree in the observation group was significantly higher than that in the control group, and the incidence of restenosis in the observation group was 4.35% which significantly lower than that in the control group 17.39% (P<0.05). Conclusion Behavior intervention combined with targeted education can not only significantly improve the medication compliance and cognitive degree, but also reduce the incidence of restenosis in patients with myocardial infarction after PCI operation
