General Abstract Submission Period: April 9–June 5, 2025 at 7:00 p.m. EDT (UTC-4)

Overall Abstract Submission Requirements

  • All abstracts must be submitted (and if accepted, will be presented) in English with accurate grammar and spelling suitable for publication.
  • Submit statistical results, including descriptive and inferential statistics.
  • Author must affirm the work submitted is original and all statements declared as facts are based on thorough examination and investigation for accuracy.
  • Authors should not "split" statistical data to create several abstracts from one study. If splitting is judged to have occurred, prior scores of related abstracts will be negatively influenced.
  • Abstracts containing identical or nearly identical data submitted from the same institution and/or people will be disqualified.
  • Proofread abstracts carefully to avoid errors before the submission deadline. The abstract will be published exactly as it has been submitted.
  • Submission of an abstract constitutes a commitment by the author(s) to present if accepted. Failure to present, if not justified, will jeopardize future acceptance of abstracts for American Heart Association meetings/conferences.
  • There is no limit to the number of abstracts an investigator may submit. If selected, the presenter must be one of the co-authors listed. If multiple submissions are accepted, the presenting author must resolve schedule conflicts by arranging for a co-author to present.

Abstract Title

  • An abstract must have a short, specific title (containing no abbreviations or inflammatory language) that indicates the nature of the investigation.
  • Avoid an abstract title that reveals the results of the study. Explicit titles denoting the findings should be used (not "Investigations of … ," "Studies of … ," etc.).

Abstract Text

  • We recommend abstracts have the following identifiable sections:
    • Introduction/Background
    • Research Questions/Hypothesis
    • Goals/Aims
    • Methods/Approach
    • Results/Data (descriptive and inferential statistics)
    • Conclusion(s)
  • Looking for recommendations on how to improve your abstract? We highly recommend you view these recommendations from AHA journals.
  • Use generic drug names.
  • Avoid beginning sentences with numbers.
  • Standard abbreviations may be used without definition. Nonstandard abbreviations (kept to a minimum) must be placed in parentheses after the first use of the word or phrase abbreviated.
  • Do not include references, credits or grant support.
  • Do not include the names or personal informationof any patient participating in the study or trial.

Abstract Review

  • Abstracts successfully submitted by the June 5, 2025, 7:00 PM ET/UTC-4 deadline are posted to a secured website for blind review. Our intent is to be inclusive of quality science received without compromising scientific integrity. As such, a team of eight to 10 experts, selected by the Committee for Scientific Sessions Programming, independently reviews abstracts in the category that best fits their expertise.
  • Abstracts submitted for consideration must convey an original idea, concept or an improvement or revision of a previous idea. Abstracts are selected on the basis of the following:
    • Scientific merit - direction toward the development of a new or improved diagnostic procedure or idea.
    • Organization – well organized, easy to follow and understand.
    • Practicality - should be available, logical and feasible.
    • Presentation - should be clear, brief and show understanding of the subject matter.
    • Technical quality - the idea must stand up to scrutiny. Facts and data have scientific backing.

Abstract Acceptance

  • Abstract acceptance/non-acceptance status will be available by mid-August. Please ensure the email provided for the presenting author is accurate as all correspondence will be sent via email to the presenting author only.
  • All communications regarding your abstract will be sent from [email protected]. Please make sure to add this email address to your email contacts to ensure important program participant-related information gets through your spam filters, etc.
  • All accepted abstracts will be scheduled in oral or poster presentation formats. All presentations including question-and-answers will be conducted in English. Presenters may request assistance from the moderator who will repeat or rephrase questions from the audience or may ask a colleague in the audience to assist with translation.
  • Guidelines for abstract presentation will be included in the acceptance communication.

Abstract Journal Publication

  • Accepted abstracts having selected "Yes" to the Abstract Copyright Transfer Agreement will be published online in the Circulation journal supplement.

Embargo Policy

  • Non-late-breaking abstracts and presentations are embargoed for release at 5:00 AM EST Monday, Nov. 3, 2025, and are therefore prohibited from release until date and time of AHA designated embargo time. You will be contacted by AHA communications if you are selected to participate in an AHA news event.
  • Written embargoed information cannot be shared with anyone outside of the AHA, except for a journal manuscript in which one-on-one embargoed media interviews can be conducted if the reporter agrees to abide by the embargo policy. Failure to honor embargo policies will result in this abstract beingwithdrawnand future abstracts also being barred from presentation. Complete AHA Embargo Policy.

Recording Policy

  • Unauthorized recording of the AHA Scientific Sessions, scientific conferences and the AHA/ASA International Stroke Conference is prohibited, whether by video, still or digital photography, audio or any other recording or reproduction mechanism. This includes recording of presentations and supportingaudiovisual materials and poster presentations and supporting poster materials.
  • The American Heart Association and American Stroke Association reserve the rights to all recordings or reproductions of presentations at AHA/ASA scientific conferences and meetings.

Use of Automated Assistive Writing Technologies and Tools

  • The use of automated assistive writing technologies and tools (commonly referred to as artificial intelligence or machine learning tools) is permitted provided that their use is documented, and authors assume responsibility for the content. As with humangenerated content, authors are responsible for the accuracy, validity and originality of computer-generated content. Automated assistive writing technologies do not qualify for authorship as they are unable to provide approval or consent for submission.
  • If the use of these technologies has involved the research design, the tools should be documented in the Methods sectionof the abstract. For additional information, see the World Association of Medical Editor recommendations.
  • For your abstract submission, you will need to indicate the use of these tools.

Before you submit your general abstract to Scientific Sessions 2025 or Hypertrophic Cardiomyopathy Medical Society at #AHA25, please use the checklist below to make sure it meets the highlighted submission guidelines and follows best practices.
