The 90th Annual Scientific Meeting of the Japanese Circulation Society (JCS2026)
 
 
Call for Abstracts
 
  Late Breaking Science Session
We strictly prohibit duplicated submission to the late breaking (clinical trials / cohort studies / basic research) and the regular abstract session.
When your abstracts submitted to the late breaking (clinical trials / cohort studies / basic research) are not accepted, we might offer the presentation at other sessions at JCS2026.
The meeting is to be held onsite; therefore, an online presentation is NOT available. If you seek any financial support to attend the meeting, you may apply for Travel Grant.
  Outline
1.  Clinical Trial
  “Clinical Trials” here are the medical studies for humans, and refer to the intervention trials on prevention, diagnosis, or treatment. Although intervention using medical supplies or medical equipment is at the core, intervention of meals, exercises, and rehabilitation could also be included. For example, the randomized controlled trial using medicine can be included in "Clinical Trials". The prospective observational study without intervention should be applied to “Cohort Studies”.
2.  Cohort Study
  “Cohort Studies” here refer to prospective epidemiological studies. These include prospective observational studies based on registry.
3.  Basic Research
  This new category refers to basic research with experimental systems using animals, cells, etc.It also includes translational research aimed at practical application in future clinical settings.
* We only accept those “Clinical Trial / Cohort Study / Basic Research” that present the latest research findings for the first time at the JCS2026.

  How to Submit Your Abstract

  Please provide information on the background, purpose, method and design, if it is the first time to announce the abstract.
