  • This weighted score is then multiplied by the area (in square millimeters) of the coronary calcification. (wikipedia.org)
  • For example, a "speck" of coronary calcification in the left anterior descending artery measures 4 square millimeters and has a peak density of 270 HU. (wikipedia.org)
  • The calcium score of every calcification in each coronary artery for all of the tomographic slices is then summed up to give the total coronary artery calcium score (CAC score). (wikipedia.org)
  • It has been used widely for assessment of coronary artery calcification with EBCT (Electron Beam CT Scanner) since the 1980s, but more recently with development of fast multi-slice technology and ECG gating, coronary angiography has become feasible. (cv-imaging.org)
  • OBJECTIVE: The effectiveness of coronary artery calcification (CAC) for risk stratification in obesity, in which imaging is often limited because of a reduced signal to noise ratio, has not been well studied. (bvsalud.org)
  • There is potential to measure CAC on chest radiographs taken for other indications, possibly allowing some primary screening for coronary artery disease without adding to radiation exposure and with minimal marginal cost. (wikipedia.org)
  • The original work, published in 1990, was based on electron beam computed tomography (also known as ultrafast CT or EBCT). (wikipedia.org)
  • The following screening investigations included in the meta‐analysis were: dobutamine stress echocardiography (DSE) (13 studies), myocardial perfusion scintigraphy (MPS) (nine studies), echocardiography (three studies), exercise stress electrocardiography (two studies), resting electrocardiography (three studies), and one study each of electron beam computed tomography (EBCT), exercise ventriculography, carotid intimal media thickness (CIMT) and digital subtraction fluorography (DSF).

  • Coronary artery calcium (CAC) progression is associated with coronary and cardiovascular event rates, but it adds only weakly to risk prediction. (medscape.com)
  • A separate study of MESA participants found patients with CAC and extra-coronary calcium (ECC) are at markedly higher risk of incident hypertension and may benefit from more intensified prevention efforts. (medscape.com)
  • A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. (wikipedia.org)
  • This severity can be presented as an Agatston score or coronary artery calcium (CAC) score. (wikipedia.org)
  • A typical coronary CT calcium scan is done without the use of radiocontrast, but it can possibly be done from contrast-enhanced images as well, such as in coronary CT angiography. (wikipedia.org)
  • However, coronary CT angiography (CTA) is superior to coronary CT calcium scanning in determining the risk of Major Adverse Cardiac Events (MACE). (wikipedia.org)
  • The Agatston score, named after its developer Arthur Agatston, is a measure of calcium on a coronary CT calcium scan. (wikipedia.org)
  • We've known about coronary calcium from the very beginning, so a big problem is individuals not learning from the past," he said. (auntminnie.com)
  • Individuals with coronary calcium at fluoroscopy were three times as likely to experience revascularization, new-onset angina, myocardial infarction, or sudden death. (auntminnie.com)
  • Coronary artery calcium (CAC) measures subclinical atherosclerosis and improves risk stratification. (bvsalud.org)
  • METHODS AND RESULTS: We identified four cardiac cohorts: 64,357 patients undergoing coronary artery calcium (CAC) scanning, 10,814 patients undergoing coronary CT angiography (CCTA), 31,411 patients without known CAD undergoing stress/rest single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI), and 5051 patients with known CAD undergoing stress/rest SPECT-MPI.
