The American Heart Association recognizes that the most exciting research is rapidly evolving and is not available for general submission.  

To highlight timely, significant and novel work at Scientific Sessions, the Committee on Scientific Sessions Program has developed a series of late-breaking sessions that allow later submission and more rapid presentation.  

Late-Breaking Basic Science Abstracts
Submission Period: Aug. 21-Sept. 3, 2008
Abstract submissions are closed.

Past late-breaking abstracts have been published as a part of the online Circulation or Circulation Research at ahajournals.org.


Late-Breaking Clinical Trials
