OBJECTIVE: According to the World Health Organization, 17.9 million individuals died from cardiovascular diseases (CVD) in 2019, constituting 32% of all global mortalities. In recent years, percutaneous coronary interventions such as stenting have become a common treatment approach for coronary artery disease (CAD). However, the problem of angina recurrence after stenting, associated with in-stent restenosis, persists. The aim of this study was to elucidate the intricate structure of relevant countries and regions, prominent research institutions, prolific authors, and recurring keywords shaping the landscape of this field.

MATERIALS AND METHODS: The search strategy involved Scopus and Web of Science Core Collection databases on December 13, 2023. Bibliometric analysis was performed using the Bibliometrix R-package.

RESULTS: An upward trend was found, characterized by an annual growth rate (AGR) of 6.82%. China leads with 17 publications, followed by Argentina with 14 and Italy with 9. Capital Medical University from China has published the largest number of articles in the field. The most significant number of publications were published in the American Journal of Cardiology. Among the top ten authors, Kim J. has published six articles and Yang C. has published four, making them the most productive in the field. “In-stent restenosis” and “percutaneous coronary intervention” were the most frequently used terms between 2002 and 2023.

CONCLUSIONS: It is important to note that the majority of studies examined were conducted in developed countries, which may influence the generalization of results. Nevertheless, there is also considerable attention to the topic from scientific groups in developing countries. This analysis helps identify gaps in the current research field and define directions for future studies.
