coronary artery calcium scoringcoronary artery diseasePURPOSE: Coronary artery calcium (CAC) scores influence the pre-test likelihood of ischemia in patients undergoing myocardial perfusion imaging (MPI). We investigated the influence of CAC score knowledge on the visual interpretation of MPI in patients...

34 Even at old age, 31% of our study population had a CAC score of 0; however, the results require careful interpretation because the proportion differed by race/ethnicity (23% in white individuals vs 35%-40% in other races/ethnicities). Atherosclerotic cardiovascular disease risk was low in...
Results of other CAC scoring systems have been reported, showing predictive capability similar to or slightly better than the Agatston score.25-28 Importantly and to our knowledge, no CAC score has previously evaluated the relationship of plaque calcium density with CVD risk. CAC is present in mor...
In summary, multiple guidelines comment on the use of CAC scoring and the common pattern is that, in certain subgroups who are below the risk threshold for preventive therapy CAC scoring may help in decision-making. Interpretation of a non-zero calcium score Traditionally, non-zero calcium scores...
Results In this study, two deep learning models were developed that automate CAC scoring using gated unenhanced coronary CT and non-gated unenhanced chest CT, respectively. Please refer to themethodssection for complete details regarding the datasets used, architecture details, deep learning model tra...
Critical to its implementation is the ability of practitioners to understand the data and the limitations of the test, as outlined in this review, and appropriately utilize this knowledge in applying the test results to the care of their patients....
Computed tomography coronary angiography has a high diagnostic accuracy for the detection of non-obstructive and obstructive CAD in high-risk asymptomatic patients with inconclusive or unfeasible stress test results. Hadamitzky et al (2011) compared CCTA with calcium scoring and clinical risk scores ...
29 Therefore, our results, which represent the prevalence and outcomes associated with CAC among younger individuals with clinical indications for CAC scoring, remain clinically relevant. There were individuals in our analysis with missing data, but most were missing only 1 risk factor, and there ...
16 Thus, we used DLR to compute the change from pretest (based on traditional cardiovascular risk factors alone) to posttest risk that was associated with the results of a subsequent test showing a negative risk marker (ie, a CAC score of 0 in this study). A DLR value greater than 1 ...
