Circulation: Heart Failure publishes several types of manuscripts under the umbrella of full-length articles. A brief description of each type follows.
Original Research Articles
Circulation: Heart Failure considers all types of original research articles, including experiments conducted in human subjects, laboratory animals, and in vitro.
- Maximum length: ≤6,000 words
The word count includes title page, abstract, text, references, tables, and figure legends
- Maximum number of references: 50
- Maximum number of figures and figure legends: 8
- Structured abstract of ≤250 words, to include the following sections: Background, Methods and Results, Conclusions
Please refer to the journal's General Preparation Instructions when submitting an original research article.
Please note that the editors invite most review articles. However, unsolicited material will be considered for publication.
- Advances in Heart Failure: Reviews will focus on topics of contemporary interest to the clinician and researcher. Overviews of new concepts in pathophysiology, natural history, diagnostic strategies, and treatment approaches will be included in this series. In addition, the series will also include cutting edge reviews of the scientific basis of disease.
- Development of Therapeutics for Heart Failure: Articles in this series will focus attention on how therapeutic strategies are developed for heart failure. The series will follow therapeutic development of drugs, devices and regenerative strategies from animal models through human studies, and critically review clinical trial methodologies as well as regulatory issues influencing heart failure therapeutics.
- Forum for Early Career Clinical Investigation: This section is devoted to publishing primary clinical research conceived and performed by early career investigators during training or during the first 3 years on faculty. This research should be performed by the primary author or in some cases an investigative cohort of authors, beginning with the initial articulation of a relevant question, through development of a strategy to address it, the personal collection of the primary data, analysis with rigorous statistical guidance as needed, and thorough interpretation of the results, limitations, and implications. Hypothesis-driven research is ideal, but reasonable questions for these exercises might also be “…what are the reasons given by clinicians in a heart failure clinic for their patients being on lower than target doses of beta-blockers? or “…how many and which patients with heart failure describe thirst as a major symptom?” We would consider publication even without a clear answer to support or refute a hypothesis, if the question and strategy were appropriate and the data and limitations were cogently analyzed. Novelty of the question and the results will be less critical in the evaluation of these manuscripts than for those submitted through the standard journal review process. However, authors are expected to demonstrate familiarity with previous studies in order to describe how their population or strategy differs, and how their results either confirm or challenge what is already known. Submissions should follow the same formatting guidelines as original research submissions but should not exceed 4,500 words in length.
- On My Mind: These articles are brief opinion essays covering a wide range of "hot" topics of relevance to the cardiovascular community. In many instances, the topic may be provocative or contentious, and this is encouraged. These articles may briefly introduce a new paradigm or idea, challenge current dogma, or raise a controversial point. This content should stimulate discussion and will be linked to an online forum (blog) to extend the discussion around the points made by the author(s). Most of these articles will be written by only a single author, but occasionally a second author can be included. These articles can be no more than 1,200 words in length (1,000 words if a table or a figure is included), and have no more than 5 references.
- E-Letters: After reading an article, readers will be able to "send a response" from a link in the content box. When submitting a response, all readers will be asked for his/her name, affiliation, email address, and comments. E-Letters will be reviewed by the editors, who will decide whether or not the response should be published. If accepted, published e-letters will appear at the end of the articles to which they relate. This feature will always relate to papers published in the journal. Unpublished observations are not considered legitimate references and e-letters citing unpublished data will not be accepted. The journal will no longer accept traditional letters to the editor submitted via its submission system.
- Images and Case Reports in Heart Failure: Clinical or basic science images (including motion studies) that illustrate either important "classic" or novel findings, provide insight into basic mechanisms responsible for cardiovascular disease, emphasize an abnormality, r elucidate a new therapy will be considered for publication in online format. The written portion of the submission should include a title page, descriptive text of no more than two pages with up to 4 references (if appropriate) and a figure legend. Movie clips are encouraged and may be submitted in any of the standard formats (e.g. avi, mov, etc) and codecs.
Please note that all manuscripts must conform to one of the above article types.
