A review of the top 25 cardiology and cardiovascular medicine journals according to the 2023 SCImago rankings revealed that all allow the use of generative AI in scientific writing within ICMJE limitations, but prohibit AI in authorship, image generation, and peer review processes, requiring authors to take full responsibility for their work. These guidelines are standardized and followed by all studied journals, emphasizing the importance of adhering to and updating these policies to uphold scientific integrity.
