“…19 However, in some patients, heart rates Յ60 bpm could not always be achieved at the expense of poor coronary artery visibility. 20 Two of the studies 21,22 excluded Ϸ30% of coronary segments mainly because of image degradation from cardiac motion. The image artifacts and the number of excluded coronary segments may be significantly reduced (to Ϸ10%) by the use of ␤-blocker and careful patient selection.…”

“…A noteworthy favorable position of this arrangement is that the image data content shows the base probability of mutilation or blunders ensuing to post handling and the most extreme determination and dim scale rendering [41,42], an inconvenience of this configuration is that it requires the pursuer to rationally recreate the 3 dimensional anatomic connections of the courses and different structures in the thorax, since the information are shown in 2 dimensional and from one perspective.…”

Aim: The point of this study was to reflectively assess the analytic exactness of multi detector angiography as a different option for conventional coronary angiography in evaluating coronary artery disease. Materials and Methods:This review study selected 57 patients, who experienced both conventional coronary angiography (CCA), and additionally multi-detector computed coronary angiography (MDCT). Aggregate of 931 open segments were studied. Of which 95 portions indicated shifted level of stenosis, with 34 segments <50% stenosis, 43 segments 50-70% stenosis and 18 segments >70% stenosis. Results:The affectability and specificity of 64 slice MDCT for identifying stenosis in <50%, 50-70% and >70% are 78.57% and 99.34%; 81.08% and 99.33%; 87.5% and 99.78%. The positive predictive value (PPV) and negative predictive value (NPV) are 78.57% and 99.34%; 83.33% and 99.22%; 87.5% and 99.78% individually. Over all exact nesses are 88.95%, 90.2% and 93.64% separately. There was no critical contrast in analytic exactness between conventional coronary angiography and 64 slice computed tomography in moderate (50-70%) and additionally severe (>70%) stenosis (p>0.05). Be that as it may, critical contrast was found in gentle (<50%) stenosis (p<0.05). Conclusion:Indicative exactness of multi detector coronary angiography (MDCT) was found to be higher in moderate and extreme stenosis and can be utilized as a substitute to conventional coronary angiography (CCA).

“…Coronary angiography is the primary diagnostic tool for atherosclerosis. Imaging, as one way of non-invasive diagnosis, has drawbacks in terms of sensitivity, specificity, and cost 1,6 . Biomarker test on the blood, such as VCAM-1, selectin and integrin are considered as one of the potential diagnostic tool 7 .…”

Introduction: Around twenty five million people in United State have at least one complications of atherosclerosis such as cardiovascular disease. Therefore screening in atherosclerotic process is important. Atherosclerosis is a multistage process that begins with damage to the endothelium due to LDL exposure. Angiography Coronary is the primary diagnostic tool for atherosclerosis. Imaging, as one way of non-invasive diagnosis, have limitation in sensitivity, specificity, and cost. Proteome urine analysis is alternative for atherosclerosis diagnostic. Objective: The aim of this study was analyse diagnostic performance of urine proteome among white rat (Rattus Novergicus strain wistar) induced by atherogenic diet. Material and methods: This study was quasi experimental in laboratory with randomized posttest only for control group design. The rat samples were divided to two groups i.e. group with atherogenic diet and non-atherogenic diet. Each group consisted of 10 rats. The treatment was done for 15 weeks. Urine sample collection was performed in week 16 of treatment. Urine proteome, collagen type I, was analyzed by ELISA to obtain biomarkers of atherosclerosis. Then determined sensitivity and specificity of the proteome urine analysis was compared with histopathology findings of the aortic arch and its branches. Result: In week 16, the researchers collected sample from 16 rats i.e. 11 rats with atherogenic diet and 5 ratswith non-atherogenic diet. Urine proteome, collagen type I, had area under the receiver operator with the characteristic curve of 98.2% (95% IK 92.6%-100%), p 0,003. The bestcut offis 0.9025 ng/ml with sensitivity of 100% and specificity of 90.9%. Conclusion: Urine proteome analyse, collagen type I, had high accuracy for atherosclerosis diagnostic.

Techniques for the Detection of Coronary Atherosclerosis: Multi–detector Row CT Coronary Angiography

Abstract: Although multi-detector row CT is a favorable alternative procedure in evaluating coronary arteries, its clinical value still is restricted to low heart rates and proximal coronary arterial segments.
