Abstract:
AIM To explore the recent research trends of rheumatic heart disease (RHD) around the world in the recent 5 years.
METHODS literatures of rheumatic heart disease published in the web of science core collection database were retrieved, and the published literatures were analyzed by CiteSpace software, including research institutions, authors, countries and key words, to draw the knowledge map.
RESULTS Totally, 2273 SCI articles were obtained. The authors of the article, Emmy Okello, Karen Sliwa, and Anna P Ralph gradually formed a core team. University of Western Australia and Emory University were important institutions for the study of RHD. Circulation, New Engl J Med and Lancet were journals with higher influence in this field. key words were rheumatic heart disease, risk, prevalence, fever, heart disease, management, children, diagnosis, atrial fibrillation and outcom, etc. It reflected that research hotspots had mainly focused on the epidemiology, clinical diagnosis and prognosis of RHD in the past five years. The main research were associated with the following diseases: Mitral stenosis, group A streptococci, atrial fibrillation, pulmonary hypertension, myocardial fibrosis, rheumatoid arthritis. During the period of 2022~2023, cardiovascular risk , mitral valve replacement, necrosis factor inhibitor, T cell and immune response had became new basic and clinical research hotspots.
CONCLUSION The study provides a new perspective for understanding the RHD and provides a theoretical reference and academic reference for related research in China, and has positive significance for the development of RHD.
