Abstract:
Objective:To analyze the research status and discuss hot topics and development trends of studies on clinical nutrition in congenital heart disease (CHD) at home and abroad, so as to provide reference for Chinese researchers.Method:Studies on clinical nutrition in CHD were retrieved from the databases of CNKI and Web of Science, from the founding of database until 2020. CiteSpace 5.6.R5 was used for visual analysis of authors, countries, institutions, research hotspots and frontiers.Results:A total of 163 Chinese and 1,809 English publications were included. The number of literatures published at home and abroad shows an overall trend of growth. The United States has the largest number of publications, with China in seventh place. Domestic publishing institutions are mainly hospitals, led by Nanjing Children's Hospital affiliated to Nanjing Medical University. Foreign publications are mainly by university institutions, with Harvard University in the United States ranking first. Research teams led by authors including Gu Ying and Ravishankar C. are at the core in this field. The most discussed issues in China are mainly nutritional risk, nutritional support and nutrient research. The main target populations are ICU patients, premature infants, infants and children, etc. The forefront of research includes early enteral nutrition, prognosis and feeding intolerance. In foreign countries, studies mainly focus on epidemiology, nutritional support, malnutrition, risk factors, nutritional treatment, energy metabolism, obesity, clinical outcomes, etc. Main target population is special population, such as neonates with CHD, infants, children, patients after heart transplantation, etc. cohort studies and researches on overweight are at the frontier.Conclusions:The research on nutrition in CHD has attracted more and more attention. There are some differences in research content and hot topics between domestic and foreign studies. Therefore, we should strengthen the cooperation and exchanges among institutions, combine the advantages of CHD nutrition research in China, and strengthen the epidemiological study of CHD nutrition and the nutrition management of CHD key population, so as to further promote research development in this field.
