急性心肌梗死患者PTSD症状网络特点分析

Network analysis on PTSD symptoms among patients with acute myocardial infarction

目的了解急性心肌梗死患者创伤后应激障碍(PTSD)症状网络的特点,探寻其核心症状。方法通过方便抽样采用问卷调查的方式对广州市两家三甲医院心内科病房256例急性心肌梗死患者进行调查,通过网络分析法分析PTSD各维度的症状网络密度及节点特性。结果142例急性心肌梗死患者存在PTSD,占55.47%。与非PTSD组比较,PTSD组各维度症状网络密度均较低;两组再体验维度及回避维度中的核心症状存在不同,症状“仿佛你再次体验创伤事件”及“回避想到或谈论创伤事件”可作为PTSD诊断关键症状,各维度的核心症状可作为干预靶点。结论从网络的视角分析急性心肌梗死患者PTSD症状间的关系并探寻核心症状可为PTSD的诊断及干预提供新思路。

Objective To describe the characteristics of post traumatic stress disorder(PTSD)symptom network and to identify core symptoms for patients with acute myocardial infarction.Methods A questionnaire survey was conducted among 256 patients with acute myocardial infarction in two hospitals in Guangzhou by convenient sampling.The symptom network density and node characteristics of each PTSD symptom were analyzed through network analysis.Results Nearly 142(55.47%)patients with acute myocardial infarction had PTSD.Compared with the non-PTSD group,the density of symptom network in each dimension was lower in the PTSD group.The core symptoms in the re-experience dimension and avoidance dimension were different between two groups.“As if you were experiencing the traumatic event again”and“Avoiding thinking or talking about the traumatic event”were the core symptoms among patients with PTSD.Conclusion The core symptoms among PTSD patients can be considered as significant target for treatment.
