Bibliometrics and visualization analysis of the domestic research of chronic stable angina in recent 15 years: based on CiteSpace software

Objectives To explore the current situation, hotspots and trends of research on chronic stable angina pectoris in recent 15 years in China, based on bibliometrics, co-occurrence analysis, cluster analysis and visualization analysis. Methods Using CNKI database as the source of literature, we collected the related research of chronic stable angina from 2004 to 2018. Citespace software was used to conduct co-occurrence analysis with authors, institutions and keywords as nodes, cluster analysis, time evolution analysis and Burst analysis of keywords, and corresponding visualization maps were drawn and analyzed. Results A total of 4 329 related literatures were retrieved, with analysis showing that the focus of research on chronic stable angina pectoris had been developing steadily in recent years, in which the outstanding contribution was represented by Yang guanlin, Liaoning University of Traditional Chinese Medicine and its affiliated hospital. Research hotspots and frontiers had been mainly focused on angina pectoris, coronary heart disease,trimetazidine, clinical research and other aspects. Conclusions Cite Space is used to analyze researches on chronic stable angina pectoris published on Chinese journals from full-text databases in recent 15 years, while intuitively represent the general situation of researches on chronic stable angina pectoris in the past 15 years, preliminarily revealing the cooperative researchers and institutions, forming a general understanding of its research hotspots, frontiers and research trends, and providing a reference for the future development direction.
