Instruction to Authors

E Journal of Cardiovascular Medicine is published quarterly (March, June, September, December). It aims to publish research articles and reviews of high quality which cover all aspects of surgery of the heart, vessels and chest.

The abbreviation of the E Journal of Cardiovascular Medicine is EJCM.

The authors hold both the scientific and ethical liability, as well as the copyright, for the manuscripts. Commercial rights of the manuscripts are transferred to the Heart and Health Foundation of Turkey. Authors are responsible for the contents of the manuscript and the accuracy of the references. All manuscripts submitted for publication must be accompanied by the Autorship Contribution Form. Once this form, signed by all the authors, is submitted, it is understood that neither the manuscript nor the data it contains have been submitted elsewhere or previously published, and authors declare the statement of scientific contributions and responsibilities of all authors. Abstracts presented at congresses are eligible for evaluation.

E Journal of Cardiovascular Medicine does not charge any article submission or processing fees.

The Editorial Policies and General Guidelines for manuscript preparation specified below are based on ICMJE “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals” by the International Committee of Medical Journal Editors.


E Journal of Cardiovascular Medicine is an independent journal based on double-blind peer-review principles. The manuscript is assigned to the Editor-in-Chief, who reviews the manuscript and makes an initial decision based on manuscript quality and editorial priorities. Manuscripts that pass initial evaluation are sent to an Associate Editor. The Associate Editor assigns the manuscript to two reviewers (internal and/or external). The reviewers must review the manuscript within 21 days. The Associate Editor recommends a decision based on the reviewers’ recommendations and sends the manuscript to the Editor-in-Chief. The Editor-in-Chief makes a final decision based on editorial priorities, manuscript quality, and Associate Editor’s and reviewers’ recommendations. If there are any conflicting recommendations from reviewers, the Editor-in-Chief may assign a new reviewer.

All manuscripts submitted are screened for plagiarism using Crossref Similarity Check powered by “iThenticate” software. Results indicating plagiarism may cause manuscripts to be returned or rejected.


Experimental, clinical and drug studies requiring approval by an ethics committee must be submitted to the E Journal of Cardiovascular Medicine with an ethics committee approval report confirming that the study was conducted in accordance with international agreements and the Declaration of Helsinki as revised in 2013. The approval of the ethics committee and the fact that informed consent was given by the patients should be indicated in the Materials and Methods section. In experimental animal studies, the authors should indicate that the procedures followed were in accordance with animal rights as per the Guide for the Care and Use of Laboratory Animals, and they should obtain animal ethics committee approval.

The presentation of the article types must be designed in accordance with trial reporting guidelines:

Human research: Helsinki Declaration as revised in 2013

Systematic reviews and meta-analyses: PRISMA guidelines, Systematic Reviews and Meta-Analyses Guidelines

Observational Studies: Observational Studies Guidelines

Authors must provide disclosure/acknowledgement of financial or material support if any is received.

If the article includes any direct or indirect commercial links or if any institution provided material support to the study, authors must state in the cover letter that they have no relationship with the commercial product, drug, pharmaceutical company, etc. concerned; or specify the type of relationship (consultant, other agreements).

Authors must provide a statement on the absence of conflicts of interest among the authors and provide authorship contributions.

In case of any suspicion or claim regarding scientific shortcomings or ethical infringement, the journal reserves the right to submit the manuscript to the supporting institutions or other authorities for investigation. The Journal accepts the responsibility of initiating action but does not undertake any responsibility for an actual investigation or any power of decision.

The manuscript should be formatted in accordance with the above-mentioned guidelines and should not exceed 3000 words.

Clinical Trial Policy

All clinical trials, which are any research projects that prospectively assign individuals or a group of people to an intervention, with or without concurrent comparison or control groups, in order to study the relationship between a health-related intervention and a health outcome, must be registered in a public trials registry acceptable to the International Committee of Medical Journals Editors (ICMJE). Authors of randomized controlled trials must adhere to the CONSORT guidelines , and provide both a CONSORT checklist (for protocols, see the SPIRIT guidance) and flow diagram. We require that you choose the MS Word template at for the flow chart and cite/upload it in the manuscript as a figure. In addition, submitted manuscripts must include the unique registration number in the Abstract as evidence of registration.  The Clinical Trial Registration Policy has been implemented in our journal as of September 2023. For more detailed instructions regarding clinical trials, please visit the guideline below:

Clinical Trials Guidelines

You can register for clinical trials by visiting the following link:

To register the relevant record in the system and learn more about the protocol to be followed, please review the link below:

The other registries are accepted by ICJME:

Introduction: Should state the purpose of the investigation and give a short review of pertinent literature.

Materials and Methods: This should be described in detail with appropriate information about patients or experimental animals. The use of abbreviations renders the text difficult to read; abbreviations should be limited to SI units of measurement and to those most commonly used, e.g. VSD, ASD, CABG (abbreviations should not be included in headings and extensions should be included at first mention).

Results: Results should be reported concisely and regarded as an important part of the manuscript. They should be presented either in tables and figures and briefly commented on in the text or in the text alone. Repetition of results should be avoided.

Discussion: The discussion is an interpretation of the results and their significance with reference to pertinent work by other authors. It should be clear and concise.

Acknowledgements: Acknowledgements and details of non-financial support must be included at the end of the text before the references. Personal acknowledgements should precede those of institutions or agencies.

References: The number of references should not exceed 40. Authors are responsible for the accuracy of the references. See References section for details about the usage and formatting required.
