Research hotspots and trends of cardiopulmonary exercise test: Visualization analysis based on citespace

ABSTRACT

The study aims to grasp the hot spots and trends of global cardiopulmonary exercise research.Web of Science (WoS) core collection and Derwent Innovation Index database were retrieved to collect literature from 2002 to 2022 with Cardiopulmonary Exercise Test (CPET) as the retrieval theme. CiteSpace was used to conduct bibliometrics and visual analysis of 6679 pieces of literature in the web of science core collection database and 251 patent data in the Derwent Innovation Index database. The results show that (1) the number of CPET theme research papers is increasing year by year, and the main research fields are cardiology, respiratory system, sports science, etc.;(2) The main research hot spots of CPET include exercise prescription, exercise and heart failure, COVID-19 cardiopulmonary rehabilitation and evaluation, etc.;(3) The development trend of CPET technology is majorly in the direction of intelligence, portability, individualization and the integration of Virtual Reality (VR) technology and evidence-based research of CPET guiding clinical decision-making.
