CTA may refine risk stratification beyond ETT in suspected CAD; hypothesis-generating and requires prospective validation before practice change.
Does coronary CTA provide incremental prognostic value compared to exercise treadmill testing in patients without known CAD?
Coronary CTA provides incremental prognostic value over exercise treadmill testing, particularly in identifying risk among patients with intermediate- to high-risk ETT results.
