Coronary computed tomography: current role and future perspectives for cardiovascular risk stratification
European Heart Journal – Cardiovascular Imaging, 05/11/2012PerroneFilardi P et al. –
The absence of coronary artery calcium (CAC) identifies asymptomatic subjects at very low cardiac risk and is reasonable in intermediate risk individuals, in whom CAC measurement reclassifies a substantial number of subjects to different risk categories. In symptomatic patients with suspected CAD, detection of non–obstructive or obstructive CAD by CCT angiography is associated with increased all–cause mortality, and provides incremental risk stratification to CAC. Further studies are needed to assess the impact of CCT on clinical outcomes and its cost–effectiveness in different clinical settings.
