Growing Evidence for Coronary Computed Tomography Angiography as a First-line Test in Stable Chest Pain

Abstract: Coronary computed tomography angiography (CCTA) is a validated technique for the evaluation of patients with suspected cor- onary artery disease, showing high accuracy compared with invasive coronary angiography and high negative predictive value. CCTA is also well positioned as a first-line test for the evaluation of stable chest pain. This purpose of this review is to examine the evidence behind CCTA in the setting of stable chest pain, with attention to 5 key strengths of a CCTA-based approach: (1) effective gatekeeping to cardiac catheter- ization, (2) selective discrimination for revascularization and tailored medical therapy, (3) advanced risk stratification, (4) improvement in outcomes, and (5) support from multisociety guidelines. Given the expansion of CT technologies to include functional strategies for eval- uating ischemia both with and without vasodilators, CCTA is poised to become the comprehensive examination for stable chest pain and anginal equivalent cardiopulmonary symptoms…
