Abstract/OtherAbstract:
Purpose:To investigate the prevalence and severity of subclinical coronary atherosclerosis and plaque characteristics in asymptomatic subjects according to the presence or absence of metabolic syndrome (MS) with multidetector computed tomography (CT).Materials and Methods:This study was approved and the requirement for informed patient consent was waived by the local institutional review board. Degree of coronary artery stenosis, multivessel involvement, and plaque characteristics, as well as coronary artery calcium score (CACS), were assessed with 64-detector row CT in 3000 age- and sex-matched asymptomatic individuals (mean age, 50.2 years ± 8.9 [standard deviation]; age range, 30-79 years). Anthropometric and metabolic profiles were also measured. Multivariate logistic regression analyses were performed to identify variables related to coronary atherosclerosis and plaque types.Results:Subjects with MS had significant coronary artery stenosis (>50% stenosis), multivessel involvement, more positive remodeling, more atherosclerotic coronary segments, and higher CACS than subjects without MS (P < .01 for all). Mixed and noncalcified plaques were also more prominent in subjects with MS than in those without MS (14.2% ± 4.4 vs 7.6% ± 3.1 and 13.1% ± 4.3 vs 7.3% ± 2.8, respectively; P < .01 for both). After adjustment for confounding factors, MS was strongly associated with significant coronary artery stenosis, multivessel involvement, and mixed plaque.Conclusion:Multidetector CT is useful in the early diagnosis and evaluation of subclinical coronary atherosclerosis in asymptomatic patients with MS; however, future prospective studies are needed to address the clinical implications of these findings.© RSNA, 2011.
