New study finds that noninvasive assessment of CAD with CCTA may help reclassify risk and predict MACE in asymptomatic atherosclerosis.

Subclinical carotid and coronary atherosclerosis burden may predict future cardiovascular events, but identification is challenging. It has been proposed that combining carotid intima media thickness and carotid plaque assessment may improve the ability to identify subclinical disease. Coronary computed tomography angiography (CCTA) directly and noninvasively assesses coronary artery disease (CAD) but its role is unclear in predicting major adverse cardiac events (MACE) in asymptomatic patients.

Prospective Study of MACE and Asymptomatic Atherosclerosis. Study of 517 asymptomatic individuals seen from 2004 to 2010, sought to evaluate the incremental contribution of subclinical carotid and coronary atherosclerosis features to risk for MACE.
CAD, Plaque Remodeling Independent Predictors of MACE. Study found that CAD ≥50% was linked to over 5 times increased risk of MACE and percent remodeled plaque independently predicted MACE. Also, the study found that a higher CACS and higher incidence of carotid disease was linked to MACE.
