#EHRA26

New data from our translational animal lab @UCPH_Research

We have talked a lot about spasms… but:

How does #PFA impact coronary vascular integrity❓❔

🔬 Key findings:
• PFA induces acute coronary endothelial dysfunction, evidenced by impaired bradykinin-mediated vasorelaxation
• The severity of dysfunction varies by location:
– Least pronounced at the CTI
– More evident in the GCV
– Most severe with epicardial application
• Smooth muscle function remained intact, as responses to nitric oxide donor (SNP) were preserved

👉🏻While vasospasms are typically reversible, our data suggest that endothelial injury persists beyond the acute phase, potentially contributing to delayed complications such as:
• Recurrent coronary spasms
• Malignant arrhythmias
• Neointimal hyperplasia and coronary stenosis

Dr. Yoshito Iesaka passed away on January 25.He was an eminent physician whose pioneering work greatly advanced the field of arrhythmia treatment. We respectfully share this news and extend our heartfelt prayers for the repose of his soul.

AMI後VFの論文がpublishされましたのでご報告致します。内容が多く二つの論文になりましたが、昔のシングルCDのカップリング曲の様に、二つで一つだと思っております。

共著者の皆様に最大の感謝をこめて🙇‍♂️
そして少しでも臨床に役立ちます様に！
