Calcium scoring (e.g., with ultrafast [electron-beam] CT, spiral [helical] CT, and multi-slice CT) for all other indications because of insufficient evidence in the peer-reviewed published medical literature; The Cleerly Coronary Report (Cleerly Labs) for the evaluation of coronary artery dise...
Coronary artery calcium (CAC) is measured using non-contrast cardiac computed tomography. CAC scoring is simple to perform, low cost, and the associated radiation dose is generally low. Higher CAC scores are associated with an increasing risk of cardiovascular disease, while the absence of CAC (...
“A friend of mine’s dad died at age 50 – a heart attack. He was scared to death of that. A lot of time people order a stress test. But that only tells you there’s obstructive coronary disease, not really telling what the big picture is. So for predictive model calcium scores, ...
Calcium scores have a high level of accuracy, due to the clarity of the results produced by the calcium procedure. The multi-slice CT scanner takes pictures of the heart in thin sections. When these images are combined, calcium deposits can be revealed, showing up as white specks. Imaging ...
Intra-class correlation coefficient between predicted and manual calcium scores was 0.98 for both cardiac and chest CT. The method showed almost perfect agreement between automatic and manual CVD risk categorization in both datasets, with a linearly weighted Cohen's kappa of 0.95 in cardiac CT and ...
The first kind CT calcium scoring is done without contrast with modern 64-slice scanners, and imaging is usually acquired in one breath-hold. This is analyzed using the rapid postprocessing software to measure the amount of coronary calcium [68]. The most commonly used scoring method is the ...
While a big proponent of cardiac CT angiography (CCTA), Leipsic said we still need to follow the guidelines, which includes not using CCTA in the setting of known disease, extremes in calcium scores or in patients with poorly controlled heart rate. VIDEO: Increased Use of Cardiac CT During...
The purpose of this study was to develop risk-adjusted multivariable models that include risk factors and coronary artery calcium (CAC) scores measured with electron-beam tomography in asymptomatic patients for the prediction of all-cause mortality. Several smaller studies have documented the efficacy ...
The CA calcium scores were directly related to the prevalence of myocardial infarction (p < 0.0001) and angina (p < 0.0001), and the aortic calcium scores were directly related to the prevalence of claudication (p = 0.001) and aortic aneurysm (p = 0.02). The extent of coronary ...
Future research needs to incorporate calcium scores with percentile rankings, larger population samples, more women with at least intermediate Framingham risk, sufficient numbers of non-Caucasians, reports on cost-effectiveness, and data on populations with Chronic Kidney Disease, End Stage Renal Disease...
