Coronary calcium progression rates with a zero initial score by electron beam tomography

International Journal of Cardiology, 2007
A review of existing literature shows that for individuals with initial coronary calcium scores (CCS) of zero it would be reasonable to consider follow-up scanning no sooner than 3 years from the initial evaluation, however the data is very limited. In this study, we sought to determine the rate of new calcifications in patients initially presenting ...

Prognostic significance of zero coronary calcium scores on cardiac computed tomography

Journal of Cardiovascular Computed Tomography, 2007
Most unexpected cardiovascular events occur in persons at intermediate risk of coronary artery disease (10%-20% 10-year risk). Coronary artery calcium (CAC) has been shown to be highly specific for atherosclerosis, occurring only in the intima of the coronary arteries. Evidence shows that elevated coronary calcium scores (CCSs) are predictive of future

Prevalence and Predictors of Atherosclerosis in Symptomatic Patients with Zero Calcium Score

Academic Radiology, 2011
Absence of coronary artery calcium (CAC) in symptomatic patients is associated with a very low risk of adverse cardiovascular events. However, patients with zero CAC may have noncalcified plaques (NCP). In this analysis, we sought to determine the prevalence and predictors of NCP in symptomatic patients with zero CAC.Coronary computed tomography ...

Absence of left ventricular concentric hypertrophy: a prerequisite for zero coronary calcium score

Heart and Vessels, 2010
The identification and intervention of factors associated with a coronary artery calcification (CAC) score of zero, suggesting the absence of significant coronary artery disease (CAD) with high probability, would be meaningful in the clinical setting. Thus far, the relationship between CAC and left ventricular (LV) hypertrophy has not been documented ...

The presence, characterization and prognosis of coronary plaques among patients with zero coronary calcium scores

The International Journal of Cardiovascular Imaging, 2010
Patients with coronary artery calcium (CAC) scores of zero are generally considered not to have atherosclerosis. Recent studies involving computed tomography coronary angiography (CTCA) challenge this assumption. This goal of the present study is to assess the frequency, morphology, location, and the prognosis of patients with plaque detected on CTCA ...
