Background:Heat stroke (HS) is an acute physical disorder that is associated with a high risk of organ dysfunction and even death.HS patients are usually treated symptomatically and conservatively;however,there remains a lack of specific and effective drugs in clinical practice.An analysis of publication contributions from institutions,journals and authors in different countries/regions was used to study research progress and trends regarding HS.Methods:We extracted all relevant publications on HS between 1989 and 2019 from Web of Science.Using the Statistical Package for Social Science (SPSS,version 24) and the software GraphPad Prism 8,graphs were generated and statistical analyses were performed,while VOSviewer software was employed to visualize the research trends in HS from the perspectives of co-occurring keywords.Results:As of April 14,2020,we identified 1443 publications with a citation frequency of 5216.The United States accounted for the largest number of publications (36.2％) and the highest number of citations (14,410),as well as the highest H-index at 74.Although the sum of publications from China ranked second,there was a contradiction between the quantity and quality of publications.Furthermore,Medicine & Science in Sports & Exercise published the most papers related to HS,with Lin MT publishing the most papers in this field (112),while the review by Knochel JP received the highest citation frequency at 969.The keyword heat-stress appeared most recently,with an average appearing year of 2015.5.In the clinical research cluster,exertional heat-stroke was determined to be the hotspot,while ambient-temperature and heat waves were the new trends in the epidemiological research cluster.Conclusions:Corresponding to this important field,while the contributions of the publications from the United States were significant,the mismatch between the quantity and quality of publications from China must be examined.Moreover,it is hypothesized that clinical and epidemiological studies may become hotspots in the near future.
