conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

results no correlation between as and history of rt, rt-to-follow-up time interval, laterality of bc, framingham’s 10-year risk score or traditional cad risk factors were detected. increase in cacs related to the senile atherosclerotic process was shown (p < 0.001). conclusions no difference between cacs was noted between bc patients with a history of 3d-crt and the non-bc women without a histo...

BACKGROUND Coronary artery calcium score incrementally improves coronary risk prediction beyond that provided by conventional risk factors. Limited information is available regarding rates of progression of coronary calcification in women, particularly those with baseline scores above zero. Further, determinants of progression of coronary artery calcification in women are not well understood. T...

Background: Although coronary calcium assessment has been demonstrated to be strongly associated with significant coronary artery disease (CAD) and future cardiac events, it is still not clear whether zero calcium on CT scan can exclude significant CAD and eliminate the need for further multi-detector computed tomography (MDCT) coronary angiography (CCTA). The purpose of this study is to test t...

introduction: the aim of this study was to evaluate the impact of measurement of coronary artery calcification score (cac) in patients with suspected coronary artery disease (cad) and a normal myocardial perfusion scan. methods: in a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of cad and a normal perfusion scan. in ...

type 2 diabetes mellitus is associated with increased inflammation and accelerated atherosclerosis. the association of the pro-inflammatory and potentially pro-atherosclerotic molecule, pregnancy associated plasma protein-a (papp-a) with diabetes and vascular diseases remains to be further established. a total of 107 patients with type 2 diabetes and 101 healthy controls participated in this st...

BACKGROUND Measuring coronary artery calcium score (CACS) using a dual-source CT scanner is recognized as a major indicator for assessing coronary artery disease. The present study aimed to validate the clinical significance of CACS in predicting coronary artery stenosis and its severity. MATERIAL/METHODS This prospective study was conducted on 202 consecutive patients who underwent both conv...
