In a multicenter, prospective, observational trial at 6 US sites, Criqui and colleagues study a diverse cohort of 3398 men and women, aged 45 to 84 years, to determine the independent associations of coronary artery calcium (CAC) volume and CAC density with incident cardiovascular disease events. In a related Editorial, Greenland discusses more evidence for CAC as a measure of cardiovascular risk.
