The foundation of every academic or professional work lies in the systematic and thorough examination of information. When seeking the results of new research, contemporary cardiologists rarely have the opportunity to read printed versions of medical journals. Instead, they rely on the Internet and various tools designed to facilitate and accelerate information retrieval, including search engines, web browsers that provide brief summary previews (snippets), online databases, and tools powered by AI-powered conversational tools. Today, digital reading also includes interactive visualizations, educational case cards, chronological overviews of specific topics, and similar features. The advantages of digital tools are exploited in numerous additional ways, with some journals generating infographic summaries for each article, podcast interviews with authors, and audio versions of published manuscripts, together with increasing user participation in public discussions through digital communities such as #CardioTwitter.

Digital reading of cardiology articles offers more advantages than disadvantages. In the dynamic digital environment characterized predominantly by HTML and PDF formats (often representing an identical copy of the printed edition), vertical scrolling represents one of the main limitations, particularly in articles formatted in multiple columns. Owing to the high level of on-screen distraction, information retention during digital reading is often short-term and focused primarily on key facts. Conversely, the advantages of digital reading include faster information retrieval, enhanced data presentation through interactive multimedia content, rapid dissemination of knowledge, improved reference management, and more effective knowledge networking. These benefits largely explain why cardiologists increasingly consume journal content in digital environments. (10–13)

Advanced AI tools are now transforming digital reading of cardiology articles from passive text consumption into an interactive and highly efficient analytical process. Their application can rapidly summarize and simplify research findings, assist in manuscript preparation and editing, and generate novel educational materials. However, studies have also identified important limitations in the application of AI-based tools, including the misinterpretation of results (“hallucinations”), the generation of inaccurate references, and related shortcomings. Consequently, verification of information sources and careful assessment of AI-generated outputs remain essential before their application in real-world settings. (14-16)

In the spring of 2026, the well-curated digital archive of the Cardiologia Croatica journal evolved into something more than a repository of published articles. A clearly structured and editorially curated archive comprising 2,124 XML files, maintained since 2014, (17) was transformed, with the assistance of a generative AI model, into a searchable and educationally valuable system that is changing the way cardiology knowledge is disseminated, acquired, and critically evaluated (Figure 1). Whereas search results were lexical in nature until 2025 (i.e., based on conventional keyword matching), the new biomedical search engine powered by advanced AI methodology is capable of understanding medical context and user intent. This “conversation with the journal” approach, enabled through AI-assisted semantic search (Figure 2), helps users to not only identify all relevant results more efficiently (Figure 3) but also gain a deeper understanding of how a particular topic has evolved throughout the journal’s publication history (Figure 4). Vector search methods (identifying relevance and contextual relationships) coupled with reduced informational noise (irrelevant data), represent key methodologies used by the AI model to retrieve relevant content accurately and efficiently. Structured filters allow users to refine search results according to author, publication year, article type, DOI, and ORCID identifiers. Responses are generated exclusively from archived journal content and are accompanied by source references. This feature is particularly important in professional and educational settings, as users must be able to verify sources, access original articles, and incorporate them into further research, writing, or learning activities. In addition to thematic chronology, the educational layer of the system includes clinical case presentations and interactive knowledge cards that guide users toward a deeper understanding of a given topic, enabling users to identify connections between sources and critically evaluate the scientific literature. Such capabilities are important because the primary challenge today often is often not limited access to scientific literature, but rather information overload and the difficulty of navigating the large volume of texts in the available literature.

At the level of the publishing industry, several solutions have emerged that aim to simplify interaction with databases containing hundreds of thousands of journals and articles, further validating this developmental approach. For example, Oxford Academic, the publisher of leading journals of the European Society of Cardiology, has integrated advanced AI technologies based on the OpenAI ChatGPT models and semantic search tools as the foundation of its database retrieval architecture, commonly referred to as Retrieval-Augmented Generation (RAG) technology. The Oxford Academic AI Discovery Assistant searches databases and clinical guidelines according to the underlying meaning of terms rather than relying solely on exact keyword matches. Information retrieval moves from hours to seconds with only a few interactions necessary to access any information, while the RAG architecture and vector searches address one of the major limitations of conventional AI applications in medicine – reliability. First, semantic search identifies the medical context of the query, and the system then searches a database of published literature and extracts the most relevant passages, which are supplied to the language model as the sole permissible source of information. This approach eliminates the risk of fabricated content or data. The AI model subsequently generates a clear response to the query within seconds while simultaneously providing references to the original publications. (14, 15, 18) Vector and semantic search technologies are also being increasingly incorporated into bibliographic and citation databases. The Wolters Kluwer company has introduced Ovid^® Discovery AI, which enables literature retrieval and filtering based on the PICO(T) clinical questions and methodology (population, intervention, comparison, outcome, and time). (19) Elsevier’s AI Discovery is a platform that enables deep semantic exploration of the Scopus database while also providing graphical representations of interconnected concepts using conceptual mapping, visually linking related research topics and facilitating a broader understanding of a given topic as well as the development of new search strategies. (20, 21)

The implementation of AI models in the dissemination of knowledge from scientific publications within cardiology is transforming the way medical insights are generated, communicated, and applied. Modern digital reading converts a published article into an interactive process of inquiry, shifting the focus from passive memorization toward dynamic reasoning. The integration of visual and audio formats enables faster comprehension of complex clinical data and extends the reach and impact of scientific publications. However, the success of this process depends on reliable technological systems, clear data sources, and a high degree of professional responsibility on the part of journal editors and publishers.
