Coronary artery calcium (CAC) is an excellent surrogate for atherosclerosis. However, this calcium is nonspecific for obstructive heart disease. This study sought to determine (1) the frequency of significant computed tomographic (CT) angiographic stenoses as a function of CAC scores, and (2) whether high CAC scores were associated with these stenoses(More)
Computed tomography (CT) detection of coronary calcium has become a popular technique for assessing coronary atherosclerosis. Whether CT detection of carotid calcium could similarly assess carotid atherosclerosis is unknown. We thus performed a study evaluating the feasibility of carotid calcium scoring by CT. We also looked for an association between(More)
BACKGROUND It is unclear whether low vitamin D is a significant risk factor for the presence of either calcific atherosclerosis or obstructive coronary artery stenoses. DESIGN In this study, we measured the 25-OH vitamin D levels of 1131 consecutive individuals who underwent coronary artery calcium (CAC) scoring and coronary computed tomographic(More)
Lowering the voltage to 100 kV is an effective method of reducing the radiation of coronary computed tomographic angiography (CTA). It is unknown, however, whether one could use a 100-kV CTA protocol with overweight or obese patients. We, thus, evaluated the effect of increasing body mass index (BMI) on various image quality parameters of 100-kV CTA. We(More)
The inflammatory biomarker high-sensitivity C-reactive protein (hs-CRP) has emerged as a predictor of future cardiovascular events. Screening for coronary artery calcium (CAC) is an alternative method for stratifying subjects by their cardiovascular risk. It is unclear, however, how hs-CRP compares with CAC scoring for the detection of obstructive coronary(More)
