Nous FMA, Budde RPJ, van Dijkman ED, et al. - Researchers retrospectively assessed the coronary calcium score, the prevalence of obstructive CAD (≥50% stenosis) ascertained by coronary computed tomography angiography (CCTA), compared clinical management and 5-year outcome in patients with and without obstructive coronary artery disease (CAD) on CCTA, and explored the potential effect of a coronary calcium score and obstructive CAD on CCTA as a manifestation of vascular disease on the CHA2Ds2VASc score and for the cardiovascular risk stratification of AF patients. A total of 94 consecutive patients without known or suspected CAD (66 (57–73) years, 68% male), who were referred for AF evaluation, who had undergone a noncontrast-enhanced coronary calcium scan and a coronary computed tomography angiography (CCTA) at the center between 2011 and 2015. A high prevalence of obstructive CAD on CCTA was found in AF patients without known or suspected CAD. It was noted that AF patients with obstructive CAD were managed differently and had a worse prognosis than those without obstructive CAD. The data considered that cardiac CT could enhance cardiovascular risk stratification of AF patients.
