Also included are editorials, readers' comments, and symposia.
If the work reported involves the use of human subjects, the author should ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association (Declaration of Helsinki) for experiments involving humans http://www.wma.net/en/30publications/10policies/b3/index.html; Uniform Requirements for manuscripts submitted to Biomedical journals http://www.icmje.org. The author should include a statement in the manuscript that informed consent was obtained for experimentation with human subjects. The privacy rights of human subjects must always be observed.
Declaration of interest
All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential competing interests include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Authors must disclose any interests in two places: 1. A summary declaration of interest statement in the title page file (if double-blind) or the manuscript file (if single-blind). If there are no interests to declare then please state this: 'Declarations of interest: none'. This summary statement will be ultimately published if the article is accepted. 2. Detailed disclosures as part of a separate Declaration of Interest form, which forms part of the journal's official records. It is important for potential interests to be declared in both places and that the information matches. More information.

Submission of an article implies that the work described has not been published previously (except in the form of an abstract, a published lecture or academic thesis, see 'Multiple, redundant or concurrent publication' for more information), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder. To verify originality, your article may be checked by the originality detection service Crossref Similarity Check.
Please note that preprints can be shared anywhere at any time, in line with Elsevier's sharing policy. Sharing your preprints e.g. on a preprint server will not count as prior publication (see 'Multiple, redundant or concurrent publication' for more information).
Inclusive language acknowledges diversity, conveys respect to all people, is sensitive to differences, and promotes equal opportunities. Articles should make no assumptions about the beliefs or commitments of any reader, should contain nothing which might imply that one individual is superior to another on the grounds of race, sex, culture or any other characteristic, and should use inclusive language throughout. Authors should ensure that writing is free from bias, for instance by using 'he or she', 'his/her' instead of 'he' or 'his', and by making use of job titles that are free of stereotyping (e.g. 'chairperson' instead of 'chairman' and 'flight attendant' instead of 'stewardess').
Changes to authorship
Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.
Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum.
This journal is part of our Article Transfer Service. This means that if the article is not accepted for publication in AJC, the Editor in Chief may suggest the possibility of transferring it to another journal for consideration for publication. You may accept or decline; if you accept, your article will be transferred automatically on your behalf with no need to reformat. More information about this can be found here: https://www.elsevier.com/authors/article-transfer-service.
Upon acceptance of an article, authors will be asked to complete a 'Journal Publishing Agreement' (see more information on this). An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement' form or a link to the online version of this agreement.
For gold open access articles: Upon acceptance of an article, authors will be asked to complete an 'Exclusive License Agreement' (more information). Permitted third party reuse of gold open access articles is determined by the author's choice of user license.Author rights

MANUSCRIPTS are received with the understanding that they are submitted solely to The American Journal of Cardiology and, that upon submission they become the property of the Publisher, that the work has not been previously published, and that the data in the manuscripts have been reviewed by all authors, who agree with the analyses of the data and the conclusions reached in the manuscript. The publisher reserves copyright and renewal on all published material, and such material may not be reproduced without the written permission of the Publisher. Statements in articles are the responsibility of the authors. The Journal does not accept original articles involving animal research.
Please note that an editable file is needed for production purposes after acceptance, and we ask that you submit source files in the event your manuscript is accepted.Study recent past issues of the Journal for format. Arrange the paper as follows: (1) title page, which should include the title, the full names and academic degrees of the authors, and current affiliations of all authors; (2) abstract; (3) text; (4) acknowledgement; (5) references; (6) figure legends; (7) tables; and (8) figures. Number the title page as 1, abstract page as 2 with the introduction beginning on page #3 and so forth. Type double-spaced (including references) with at least 25-mm (l-inch) margins, sized for 8.5 x 11 inch paper. Files should be labeled with appropriate and descriptive file names. Upload text, tables and graphics as separate files. Do not import figures or tables into the text document. Complete instructions for electronic artwork submission can be found on the Author Gateway, accessible through the journal home page.
Title Page and Abstract
For the complete title page, include the full first or middle and last names of all authors. List the current affiliations of all authors and link author names and affiliations by “a,” “b,” “c,” etc., after the author names and before the affiliation. Provide information about grant support if necessary, including the location (City/state/country). If work described is supported by a grant from a pharmaceutical company, that fact should be stated on the title page.

List 2 to 4 key words for subject indexing at the end of the abstract.
Highlights are optional yet highly encouraged for this journal, as they increase the discoverability of your article via search engines. They consist of a short collection of bullet points that capture the novel results of your research as well as new methods that were used during the study (if any). Please have a look at the examples here: example Highlights.
Highlights should be submitted in a separate editable file in the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters, including spaces, per bullet point).Style
Use the required 3 major headings throughout the body of the text, such as Methods, Results, and Discussion. Do not use subheadings under these headings. Tables, figures, and references must be cited in numerical order throughout the manuscript. Abbreviations are permitted, but usually no more than 5 or 6 per manuscript (at the Editor's discretion), and then they must be used on every page of the manuscript after they are initially spelled out (followed by the abbreviation) in both abstract and introduction. Use generic names of drugs. Do not spell out any number, including those less than 10, except when used for opening a sentence, but try not to begin sentences with a number. Use symbols for less than (<), greater than (>) and percent (%). Indent all paragraphs after the abstract and introduction. Both the abstract and introduction should be a single paragraph.

The Digital Object Identifier (DOI) may be used to cite and link to electronic documents. The DOI is a unique alpha-numeric character string assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly articles in press, because they have not yet received their full bibliographic information.
Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author or a link will be provided in the e-mail so that author can download the files.The PDF proofs can be annotated, for which you will need to download Adobe Reader version 7 (or higher) available free from http://get.adobe.com/reader. Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site: http://www.adobe.com/products/reader/tech-specs.html.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the query form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If this is not possible, then mark the corrections and any other comments (including replies to the query form) on a printout of your proof and return by fax, or scan the pages and send by e-mail or by post. Please use this proof only for checking the typesetting, editing, completeness, and correctness of the text, tables, and illustrations. Significant changes to the article as accepted for publication will be considered at this stage only with permission from the Editor. We will do everything possible to get your article published quickly and accurately – please let us have all your corrections within 48 hours. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility. Note that Elsevier may proceed with the publication of your article if no response is received.
Online proof correction
Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF.
