2- Body of the manuscript: No specific structure is required. The word count must be respected.

3- Figures and tables
• The number of tables and figures recommended for this type of manuscript can be found by accessing the summary table.
• Tables: These should be numbered by order of appearance and adopted when necessary to help the readers understand the contents laid out in the manuscript. Tables should not contain any data previously reported in the text. Indicate the footer markers in the following order: *, †, ‡, §, //, ¶, #, **, ††, etc. Tables must be edited in Word or similar software. The authors should use the standard tables and figures recommended by ABNT. According to these standards, tables should not have any side lines, should be identified by number and title, which should come above the table. The source, even if it is the author himself, should come below it.
• Figures: Figures must be in good resolution so they can be evaluated by the reviewers. As per the ABNT standards, illustrations must present a descriptive word, the number according to the order of appearance, and the title above the image. The source should come below. Any abbreviations used in the illustrations should be explained in the legends.
It is desirable that figure 1 be the one that best summarizes the main data of the manuscript, i.e., the main illustration for the manuscript results. Collages of images can be included.
Figures and illustrations should be attached in separate files, in the appropriate section in the system, with a JPEG, PNG or TIFF extension.
• Images and videos: Approved manuscripts containing scans (e.g., echocardiograms and coronary angiography films) should be submitted via the manuscript submission system as motion pictures in MP4 format.
