Coronary disease & ACS

Anatomical vs Physiological Lesion Characteristics in Prediction of Acute Coronary Syndrome

JACC Cardiovasc IntervPublished Case-control study

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.
