The prognostic ability of the Agatston score was found to be improved by determining how many vessels had coronary artery calcium (CAC). Compared with single vessel involvement, 2-vessel CAC increased mortality (HR=1.6) and 3-vessel involvement even more (HR=1.99). Left main CAC and diffuse CAC were also associated with increased mortality. (Am J Cardiol. 2015 Feb 12)Read More

Atherosclerotic Plaque Characteristics by CT Angiography Identify Coronary Lesions That Cause Ischemia: A Direct Comparison to Fractional Flow Reserve.
Percent vessel stenosis of the coronary arteries is not a uniform predictor of myocardial ischemia. Other important factors include the atherosclerotic plaque characteristics of aggregate plaque volume percent, positive remodeling, low attenuation, and spotty calcification.
