ISTH 2026 Congress Paris Opens with a Powerful Message: Science Beyond Border

A Historic Return to Paris Celebrating Global Collaboration, Innovation and Scientific Excellence

The opening ceremony of the 34th Congress of the International Society on Thrombosis and Haemostasis (ISTH 2026) in Paris set the tone for a landmark scientific gathering — one defined not only by groundbreaking research, but by a shared global commitment to advancing patient care.

Twenty-five years after ISTH last convened in Paris, the Society returned to the French capital with unprecedented international participation and a clear message: the future of thrombosis, hemostasis and vascular biology will be shaped by collaboration that transcends borders.

From emerging therapies and transformative discoveries to global health initiatives, ISTH 2026 highlighted the power of science when knowledge, expertise and perspectives come together.

ISTH 2026 Reaches New Milestones

The scale of this year’s congress reflects the continued growth and global impact of the ISTH community.

The meeting achieved several historic milestones:

• More than 6,850 registered participants, representing the highest attendance since 2017.
• 3,188 scientific abstracts, marking the largest number submitted since 2009.
• Participants from more than 100 countries, demonstrating the truly international reach of the Society.

These numbers represent more than attendance statistics — they reflect a global scientific community united by a common goal: improving understanding, diagnosis and treatment of disorders affecting millions of patients worldwide.

Beyond Numbers: Defending Science Through Collaboration

While the impressive figures highlighted the strength of the congress, the opening ceremony focused on a deeper message: scientific progress depends on trust, collaboration and integrity.

Speakers addressed the evolving challenges facing biomedical research, including declining public confidence in science and increasing pressures on research funding.

Despite these challenges, ISTH reaffirmed its commitment to advancing evidence-based medicine, rigorous scientific investigation and international cooperation.

In an era where medical knowledge continues to expand rapidly, maintaining scientific credibility remains essential for translating discoveries into meaningful improvements in patient care.

Honoring Scientific Excellence and Lifetime Contributions

A highlight of the opening ceremony was the recognition of outstanding leaders whose work has shaped the field of thrombosis and hemostasis.

The prestigious Robert P. Grant Medal, the highest scientific honor awarded by ISTH, was presented to Professor Frits Rosendaal in recognition of his exceptional lifetime contributions to thrombosis research.

The Harold R. Roberts Award honored Professor Donald M. Arnold for his remarkable scientific achievements and leadership.

These recognitions celebrate not only individual accomplishments, but also the importance of mentorship, collaboration and scientific curiosity in advancing the next generation of researchers and clinicians.

A Stronger Global Vision for Thrombosis and Hemostasis

The opening ceremony also highlighted ISTH’s strategic priorities for 2025–2027, emphasizing areas where global collaboration can make a significant impact.

Key priorities include:

• Advancing women’s health and pregnancy-associated thrombosis care
• Expanding education and scientific exchange worldwide
• Strengthening international partnerships
• Improving awareness and management of bleeding disorders
• These initiatives reflect the Society’s evolving role — not only as a scientific organization, but as a global leader addressing unmet needs in patient care.

Where Evidence Meets Impact

For clinicians, researchers and healthcare professionals, ISTH 2026 represents far more than a traditional scientific meeting.

It is a place where:

1. new evidence becomes clinical practice,
2. collaborations become discoveries,
3. scientific discussions shape the future of medicine.

Across thrombosis, hemostasis and vascular biology, the congress provides a unique environment where experts from different disciplines and regions come together to solve complex medical challenges.

Science Beyond Borders: The Future of Hemostasis and Thrombosis

The opening ceremony of ISTH 2026 captured the true spirit of the congress: progress is not driven by discovery alone.

It is built through curiosity, collaboration and a shared responsibility to improve health outcomes worldwide.

As the global thrombosis and hemostasis community gathers in Paris, one message stands clear:

The future of medicine will be defined by science without borders.
