Abstract The present research intends to analyze and construct the networks of co-authorship in the research domain of chronic cardiovascular failure based on the centrality indicators of social network analysis. This applied research has been conducted using the common methods in scientometrics through analysis technique of co-authorship and network analysis method. The research community include 11967 documents in the topic of “chronic heart failure” during 2000 to 2015 being in the category of “cardiovascular systems” at Web of Science.

Overall, 473 top authors were identified in this domain,analyzed through BibExcel and UCINET and the networks were illustrated with VOSviewer. SPSS® was utilized to test the hypotheses. The findings show that Anker SD is the highly active and mostly cited researcher in the domain of chronic heart failure. Voors AA and vanVeldhuisen DJ have the highest paired co-authorship among the writers in the domain of chronic heart failure. The highest rate of scientific collaboration stands among the researchers in Italy and the U.S.A.
