Background—There is a clear relationship between absolute calcium scores (CS) and
severity of coronary artery disease. However, hard coronary events have been shown to …

Objectives: We sought to assess the natural history of a cohort of asymptomatic individuals
with very high (≥ 1,000) calcium scores (CSs) on a screening electron beam tomography …

Background Prediction of hard cardiac events (myocardial infarction and coronary death)
remains difficult in spite of the identification of several relevant risk factors for the …

Background Electron beam tomography coronary calcium imaging is an evolving technique
for the early detection of coronary atherosclerosis, and recent studies have established its …

BACKGROUND: Most unexpected cardiovascular events occur in persons at intermediate
risk of coronary artery disease (10%–20% 10-year risk). Coronary artery calcium (CAC) has …

Background—Conventional coronary artery disease (CAD) risk factors fail to explain nearly
50% of CAD events. This study examines the association between electron-beam …

Background—Detection of subclinical coronary artery disease (CAD) before the
development of life-threatening cardiac complications has great potential clinical relevance …

Objectives: This study examined a large cohort to assess whether progression of coronary
artery calcium (CAC) was associated with all-cause mortality, and which among 3 different …

Background—Prognostic risk models have had limited success in predicting coronary
events in subjects with multiple risk factors. We and others have proposed an alternative …

Objective: To compare the presence and extent of coronary calcifications in young patients
with first, unheralded acute myocardial infarction with matched controls without a history of …
