Anatomical vs Physiological Lesion Characteristics in Prediction of Acute Coronary Syndrome
Authors' conclusion
Luminal narrowing, plaque quality and quantity, and local hemodynamics were independent predictors of ACS, offering specificity in physiology and sensitivity in anatomy. A comprehensive assessment of them further refined the risk prediction for future ACS.

- ΔFFRCT vs Combined anatomy: P = 0.748 — similar predictability, with additive discrimination towards each other
- Lesions that became ACS culprits
- 363 (14.8%)
- All anatomical and simulated physiological characteristics independently associated with culprit lesions
- all P < 0.001
