摘要:
目的:调查心尖球形综合征(takotsubo cardiomyopathy，TTC)研究文献，分析当前该主题的研究热点。方法： 对PubMed数据库中2009~2011年发表的有关TTC的文献进行调查分析，统计主要主题词出现的频次，截取频次大于6次的主题词作为高频次主题词。两两统计高频次主题词在同一篇文献中出现的频率，形成主题词词篇矩阵，利用SPSS统计软件对矩阵进行聚类分析，通过分析各类的文献内容得到该主题的研究热点。结果： 共检出近3年发表的有关TTC论文646篇，出现频次超过6次的主题词为34个，其中出现频次最高的主题词为TTC的诊断（为228次），通过对这34个高频次主题词聚类分析得到10个研究热点。结论： 肾上腺肿瘤与TTC发病的关系、药物诱导的TTC、TTC发病与基因、TTC胸痛及冠脉病理、TTC的MRI诊断与药物治疗、TTC并发症、TTC与长QT间期综合征的关系及与心肌梗死的鉴别诊断、超声及放射性核素成像对TTC心功能的评价、TCC的放射诊断、治疗及蛛网膜下腔出血并发症与TCC，均为近3年TTC的研究热点。
Abstract:
AIM:To examine “hot” topics on Takotsubo cardiomyopathy (TTC) research by analyzing the related literature. METHODS: Articles related to TTC published in the PubMed database during the years 2009 to 2011 were selected. Subject heading (MeSH) terms of the articles were downloaded and the frequency of the major MeSH terms was statistically calculated. High-frequency MeSH terms in the literature formed the co-word matrix by the appearance frequency of a pair of MeSH terms in the same literature. The co-word analysis was used to cluster these medical MeSHs. The research focus was obtained after statistically analyzing the contents of each cluster. RESULTS: A total of 646 articles associated with TTC were found in the PubMed database and 34 MeSH terms appeared more than six times. The MeSH term “Takotsubo cardiomyopathy/diagnosis” was found with the highest occurrence frequency (228 times). The 34 over-6-time terms were clustered into ten groups according to their co-occurrence. CONCLUSION: The ten "hot" topics for the past 3 years, respectively, are relationship between incidence of adrenal tumors with TTC; drug-induced TTC; TTC and genetic disease; TTC chest pain and coronary pathology; MRI diagnosis and drug treatment of TTC; complications of TTC; TTC and long QT syndrome and myocardial infarction with differential diagnosis; ultrasound and radionuclide imaging appraisal of cardiac function of TTC; diagnosis and treatment of radiation in TCC; and complications of subarachnoid hemorrhage and TCC.
