The Heart Failure Association of the European Society of Cardiology annual meeting (HF-ESC) typically hosts 5,000+ attendees, and the conference showcases novel research in heart failure and cardiomyopathies across ~100 sessions and 1,000+ abstracts. HF-ESC usually releases abstract titles for the final program ~4 weeks before the conference starts, but the release of abstracts has been more unpredictable historically, ranging from 1 week before to multiple days after the conference has started.
