Christoph B Olivier’s Team Explores Platelet Reactivity and Fibrin Clot-Strength in AF

Jan Hartmann, Chief Medical Officer at Haemonetics, reposted from Haemonetics on LinkedIn:

”Encouraging progress in personalized cardiovascular care.

A recent paper from Christoph B Olivier’s team at my alma mater, The University of Freiburg, explores “Platelet Reactivity and Fibrin Clot-Strength as assessed by TEG in Patients with Atrial Fibrillation undergoing Percutaneous Coronary Intervention”.

Their findings suggest that combined high platelet reactivity and increased platelet–fibrin clot strength after the PCI may elevate ischemic risk—though neither factor alone was predictive.

This aligns with data in broader post-PCI populations, with or without AFib:

  • Young-Hoon Jeong, MD, PhD’s team (European Heart Journal, 2024) in South Korea showed that patients with combined platelet-fibrin clot strength and high platelet reactivity had the highest risk for MACE post-PCI (more than patients with either factor alone).
  • A 2023 study from Fudan University in China reported similar results, where “a combination of high fibrinogen and HRPR may identify recurrent adverse ischemic events over 12 months.”

It’s encouraging to see continued momentum toward individualized post-intervention strategies, especially in tailoring OAC and antiplatelet therapy.
