Instructions to Authors
Iranian Heart Journal is the official quarterly publication of the Iranian Heart Association and publishes original papers, case reports, and brief communications on topics in pediatric and adult cardiology, cardiac surgery, cardiac anesthesia, and related issues from all over the world.

In order to submit a paper, you are kindly requested to read and observe the following guidelines carefully. Authors are notified when a manuscript is received. Each article is considered individually and undergoes a careful review process by the Editorial Board. Additional review may be requested from specialists in the related field. The final decision regarding acceptance or rejection of an article will be forwarded to the corresponding author as soon as possible. Accepted articles for publication will undergo corrective formatting and editing by the Technical Editor (s) who reserves the right to make any changes or deletions necessary in order to make the paper suitable for publication and update it to Iranian Heart Journal’s format. Received manuscripts will not be returned unless specifically requested by the author and accompanied by a self-addressed, stamped envelope.

Previous presentation of the work in medical congresses or symposiums are acceptable but must be mentioned in the footnotes.


Generic names instead of trade names must be used for medications (eg, propranolol instead of Inderal®) and standard abbreviations may be used after presenting the unabbreviated form in the text. Manuscripts not meeting these criteria will be returned to the authors for correction before undergoing evaluation by the Editorial Board for publishing.
