Objective: this study investigates the conducted research in the cardiovascular chronic disorder field in various aspects (citing analysis, scientific cooperation network, geographic distribution, target journals, metric of intelligence and synonyms). Materials and methods: this study was carried out using science survey techniques. First, data selection is significantly important in science survey research and data have a direct influence on the findings and results and hence, it’s better for the initial records to be adequately inclusive and exclusive. Given this fact, the articles with the subject of “cardiovascular chronic disorder” in English in the years 2000 to 2015 classified under “cardiovascular systems” of Web of Science” were retrieved in this research. In this regard, the following search method was used and resulted in the restoration of 11967 documents (articles, reviews and proceedings). Results: the findings of this study indicated that the quantitative process of scientific production in the field of cardiovascular chronic disorder has had a relative growth. Three researchers with the most scientific productions were able to gain the highest H index and merely 10 journals (5.07%) published more than 43% of the articles (5202 titles) in the cardiovascular chronic disorder and USA with 4431 research (37%) with the subject of cardiovascular chronic disorder was in the first place by a great distance, compared to other countries of the world. Moreover, the findings of this study suggest that the most frequent keywords of such collected research were classified into 7 main clusters. Conclusion: there is a great difference between countries’ share and journals’ share in scientific production in the field of the cardiovascular chronic disorder. Conflict of interest: none declared M3 ER -
