      The risk for sudden cardiac death (SCD) climbs steadily in tandem with coronary artery calcium (CAC) burden, independent of more conventional risk factors, in primary-prevention patients considered low- to intermediate-risk, researchers say. The findings, based on a large cohort study, strengthen the case for initial CAC imaging as a gatekeeper to further testing in such patients who have mostly subclinical atherosclerotic cardiovascular disease (ASCVD), they conclude.

        @nakul The study's 66,636 primary-prevention patients, part of the Coronary Artery Calcium Consortium observational cohort, were without known coronary disease at enrolment, from 1991 to 2010, at four major American centers. They had been referred to CAC imaging because of the presence of at least one ASCVD risk factor, such as dyslipidemia, family history of premature heart disease, hypertension, or diabetes, the researchers note.
