Prognostic significance of coronary artery calcium in asymptomatic subjects with usual cardiovascular risk.

Background: Coronary calcium detected noninvasively is an attractive way to diagnose atherosclerosis before the development of symptoms. This study examines the prognostic value of coronary calcium in asymptomatic subjects with usual cardiovascular risk.

Methods And Results: In 425 asymptomatic subjects, 229 men (aged 45.

Coronary calcium detected by digital cinefluoroscopy and coronary artery disease in patients undergoing coronary arteriography: effects of age and sex.

Background: Coronary artery calcium, detected non-invasively, correlates well with angiographically documented coronary artery disease (CAD). This study was conducted to evaluate the diagnostic efficacy of coronary artery calcium detected by digital cinefluoroscopy for CAD and assess the effects of age and sex on it.

Methods: In 242 patients who underwent coronary angiography, coronary calcium status was determined and related to angiographic findings.
