Purpose

The objective of the PLATFORM Study is to compare clinical outcomes, resource utilization, and quality of life (QOL) of FFRCT-guided evaluation versus standard practice evaluation in patients 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
