Visualization Analysis of Cardiovascular Risk Factors Based on Knowledge Mapping

To provide guidance for the study of risk factors of cardiovascular disease in China, we analyze and compared the research hotspots and frontiers of cardiovascular risk factors in China and outside China in this paper. The CiteSpace software is used to visualize the research literature on cardiovascular risk factors from Cnki(China Knowledge Network Internet) and Web of Science core collection database from 2010-2018, and to draw the knowledge map of high-frequency words, research institutions and countries. In this project, a total of 318 Chinese literatures and 9,009 English literatures were screened out as research objects. The number of annual publications assumes an increasing tendency, most of which are concentrated in developed countries or regions. Study of cardiovascular risk factors outside China is significantly taken more seriously than in China. This study shows that the research frontier has already been extended to lifestyle, particulate air pollution, socioeconomic status, depression, stroke and breast cancer, etc. Moreover, children, adolescents and women have been more concerned in the target population. In consideration of the main reasons for cardiovascular disease---Hypertension, diabetes, coronary heart disease, obesity, atherosclerosis and metabolic syndrome, etc., we should pay close attention to the influence on the risk of cardiovascular disease produced by psychological state, living habits, regional differences, air pollution and so on. Meanwhile, we also need to take the screening and prevention of cardiovascular risk more seriously among adolescents.
