We aim to shed light on future studies by conducting a comprehensive bibliometric analysis of the literature on pregnancy hypertension.Material and Methods: In this study, articles published in the Web of Science Core Collection on hypertension in pregnancy between 1975 and 2019 were evaluated. Documents produced in 2020 excluded. The words "pregnancy" and "hypertension" were used as keywords for database scanning. Gunnmap web-based application used to visualize the scientific efficiency of countries. The Vosviewer (Version 1.6.14) program was also used to display bibliometric connections of data.Results: Two thousand, one hundred and twenty articles on the subject were identified. It has been observed that the number of citations to articles and articles published in recent years on hypertension in pregnancy has reached a peak. The USA and the UK were identified as the countries with the most articles published and the most cited journals. China and India have also been found to be countries with increased productivity over the past decade.Conclusion: With this study, we have determined the most active journals, universities and authors on the subject. We have shown that the issue of hypertension during pregnancy is a field of study in which scientific publications are increasingly published. We believe that our analyses will be a guide for future studies on hypertension during pregnancy.
