Assessing left main bifurcation anatomy and haemodynamics as a potential surrogate for disease risk in suspected coronary artery disease without stenosis - Scientific Reports Scientific Reports - Assessing left main bifurcation anatomy and haemodynamics as a potential surrogate for disease risk in suspected coronary artery disease without stenosis

🫀💡We've shown that the coronary artery's anatomy can predict early atherosclerosis.

✅ 127 CTCA
✅ 11 anatomical features
✅ >75% of flow variance explained

👉 New risk markers via routine imaging

Our @SciReports study shows that simple CT-based geometry of the left main predicts flow disturbances driving plaque formation.

No CFD. No stenosis. Just anatomy → risk insight. 🫀

🩺 How accurate are simplified #CFD models in coronary flow analysis?

Our latest study compares the flow-split outflow strategy to the gold-standard multiscale simulation across resting & hyperaemic conditions.

Sex-Specific Variances in Anatomy and Blood Flow of the Left Main Coronary Bifurcation: Implications for Coronary Artery Disease Risk Studies have shown marked sex disparities in Coronary Artery Diseases (CAD) epidemiology, yet the underlying mechanisms remain unclear. We explored sex disparities in the coronary anatomy and the…

🫀 Why do men and women experience coronary disease so differently?

Our work revealed distinct anatomical and blood flow patterns in the left main coronary bifurcation — even in patients without stenosis.

Turns out the shape of your arteries really matters! New research by @susannbeier.bsky.social & colleagues shows that when blood flow gets turbulent, it can quietly damage artery walls long before clogs form - a faster way to spot heart risk early.

🫀 @SciReports
Our study of 127 CTCA scans reveals that key left main coronary anatomy features, like vessel twists, predict *early* coronary disease.

This could enable early risk assessment from standard imaging 🧠💻

interesting. i like HeartFlow to 'see' soft and calcified 'plaque burden'
.
but here reduced MACE in cabg pts going back for pci:
