 The OVERALL OBJECTVE of this post-market, multicenter, longitudinal, prospective, consecutive cohort study is to compare clinical outcomes, resource utilization, and quality of life QOL in subjects receiving standard practice evaluation and treatment versus subjects receiving FFRCT-guided evaluation and treatment in subjects with suspected CAD in order to further inform patients, health care providers, and other stakeholders about which technologies are most effective and efficient in the diagnosis of CAD. Cohort 1 of this study will assess outcomes incorporating standard practice evaluation and Cohort 2 will assess outcomes incorporating FFRCT-guided evaluation. Each Cohort will be further delineated based upon initial presentation, whereas subjects presenting for initial non-invasive testing will be designated as Cohorts 1A and 2A; and subjects already referred for ICA will be designated as Cohorts 1B and 2B.
