Abstract
Background: Coronary CT angiography (CTA) is a noninvasive imaging modality with an excellent diagnostic accuracy for the detection of coronary artery disease (CAD) in both men and women. Given the uncertain diagnostic accuracy of functional tests in women, direct visualization of CAD by CTA may be particularly effective in women. Purpose: We sought to evaluate the value of coronary CTA in the diagnostic workup of women presenting with stable chest pain. Methods: From 2014 to 2017, 375 consecutive outpatients with new onset chest pain were referred to our tertiary centre. Out of these, 231 had no history of CAD and presented intermediate pre-test probability of CAD. According to care decisions of the attending physician, patients receiving usual care functional testing plus CTA were 113 (49%) and patients receiving CTA as first-line investigation were 118 (51%). All patients underwent a dual-source CTA scan (48% with standard mode and 52% with low dose mode). Obstructive CAD (O-CAD) was defined as >50% stenosis in principal branches of left or right coronary artery.
