Authors' conclusion

The use of the pooled cohort equations to risk stratify women for MACE underestimates risk in women with a low predicted risk. BAC is independently associated with an increased risk of MACE and may be useful as an incremental risk modifier.

Women aged 40 to 75 without coronary artery disease who underwent a routine screening mammogram
