摘　　要：目的探讨分析近5年心脏性猝死(sudden cardiac death,SCD)的研究热点。方法采用PubMed数据库,检索式为"Death, Sudden, Cardiac"[Mesh] AND ("2013/03/14"[PDat]:"2018/03/12"[PDat]),检索结果采用书目信息挖掘系统(BICOMB)软件进行常规文献计量学分析,使用g CLUTO 2.1软件进行聚类及可视化分析。结果共检索到文献3090篇,统计分析后将SCD研究热点划分为7个主题:避免年轻运动员心脏疾病猝死的检查、植入式心脏复律除颤器(ICD)治疗心源性猝死、ICD预防年轻运动员由肥厚型心肌病引起的心律失常、不同年龄段SCD患者心脏病理损害差异、预防SCD植入ICD、SCD的预测因素及引发SCD的心脏相关性疾病。结论双聚类研究热点分析方法很好地体现了目前SCD的研究方向,可为科研选题提供参考。Objective To explore and analyze the research hotspots of sudden cardiac death(SCD)in the past five years.Methods The Pubmed database was used,and the search formula was"Death,Sudden,Cardiac"[Mesh]AND("2013/03/14"[PDat]:"2018/03/12"[PDat]).The results of the search were analyzed by the Bibliographic Item Co-occurrence Matrix Builder(BICOMB)software for routine bibliometric analysis,and clustering and visual analysis were performed using gCLUTO 2.1 software.Results A total of 3090 articles were retrieved.After statistical analysis,the SCD research hotspots were divided into seven topics:examinations to avoid the death of young athletes due to sudden cardiac disease,implantable cardioverter defibrillator(ICD)for treatment of sudden cardiac death,ICD preventing arrhythmias caused by hypertrophic cardiomyopathy in young athletes,differences of cardiac pathological damage in patients with SCD at different ages,implantation of ICD to prevent SCD,predictors of SCD,and cardiac-related diseases that trigger SCD.Conclusion Application of biclustering analysis method in analyzing research hotspots can well reveal the current research direction of SCD,which can provide reference for scientific research topics.
