Key result
Bibliometric analysis reveals PCI prognosis research shifting toward risk factors, Traditional Chinese Medicine, and anxiety.
Why the study?
Despite increasing studies on PCI strategies, fewer studies have reported the mapping of knowledge structure and hotspot analysis regarding the prognosis of patients undergoing PCI.
This bibliometric analysis highlights a shift in PCI prognostic research towards risk factor management, cardiac rehabilitation, and emerging areas like anxiety and Traditional Chinese Medicine.

Shifts in PCI prognosis research warrant caution before adopting TCM or anxiety-focused strategies; leaves open need for prospective outcome trials.
BACKGROUND: The number of patients undergoing percutaneous coronary intervention (PCI) procedures is increasing along with the number of studies involving guidelines, prognostic assessments, and cardiac rehabilitation related to PCI strategies. However, fewer studies have reported the mapping of knowledge structure and hotspot analysis in this field. Our goal was to discuss and analyze the current status, hot spots and developmental trends associated with research into the prognosis of patients undergoing PCI, and to provide reference for PCI-related research. METHODS: The Web of Science Core Collection and China Knowledge Network were searched for relevant literature from January 2003 to October 2022, and CiteSpace 6.1. R3 software was used to analyze the co-occurrence, clustering, and emerging authors, institutions, and keywords. RESULTS: A total of 2666 English and 2010 Chinese publications were included. The number of publications showed a growing trend. The author with the maximum number of articles was Xu Bo. The institutions with high productivity were Peking Union Medical College and Capital Medical University. Although the number of Chinese articles was high, the cooperation between institutions was low and the impact was small. The results of the analysis suggest a shift in the focus of keywords from coronary artery disease and PCI to studies involving the assessment and intervention of risk factors associated with poor prognosis of PCI. Traditional Chinese Medicine and anxiety represent the emerging direction of PCI prognosis. The assessment of major adverse cardiovascular events and cardiac rehabilitation require careful analysis in post-PCI research. CONCLUSION: The findings of this bibliometric study present a comprehensive and systematic overview of the PCI prognosis, based on the analysis of the current status and trends in research, which may facilitate the identification of hot topics and new directions for future research.

Guo et al. (2023) studied PCI prognosis (n=4,676). Bibliometric analysis was evaluated on Co-occurrence, clustering, and emerging authors, institutions, and keywords. A bibliometric analysis of 4676 publications from 2003 to 2022 revealed a research shift toward risk factor assessment, Traditional Chinese Medicine, and anxiety in PCI prognosis.
