How common is asymptomatic coronary atherosclerosis, and what is the subsequent risk of myocardial infarction?
By an average age of 60 years, screening of asymptomatic people using coronary CTA will identify atherosclerosis in approximately 60% of men and 36% of women. A small proportion will have coronary artery partial obstruction. This group, as well as people with extensive atherosclerosis, regardless of level of obstruction, is at higher, but still low, risk of myocardial infarction (MI) over the next few years. This study was not designed to compare the benefit of screening with no screening, and we need more information before we start screening people for atherosclerosis. 1b
