Assessing Diagnostic Value of Non-invasive FFR-CT (Fractional Flow Reserve - Computed Tomography) in Coronary Care in the Emergency Department

Overview

This is a prospective multi-center study. All clinically stable, symptomatic patients who present to the emergency department (ED) or observation unit with suspected coronary artery disease (CAD) and who have at least one ≥40% lesion and no lesion \>90% confirmed by CCTA (Coronary Computed Tomography Angiogram) are eligible for enrollment once their CCTA has been completed and their FFR-CT (if applicable) has been ordered. All enrolling sites will have CCTA incorporated into their standard evaluation of chest pain in the ED/observation unit. Non-control sites will have CCTA and FFR-CT analysis incorporated into their standard evaluation of chest pain in the ED/observation unit.

This is a prospective multi-center study. All clinically stable, symptomatic patients who present to the ED or observation unit with suspected CAD and who have at least one ≥40% lesion and no lesions \<90% lesion in a major vessel, confirmed by CCTA, are eligible for enrollment once their CCTA has been completed and FFR-CT (if applicable) has been ordered. All enrolling sites will have CCTA incorporated into their standard evaluation of chest pain in the ED/observation unit. Non-control sites will have CCTA and FFR-CT analysis incorporated into their standard evaluation of chest pain in the ED/observation unit. All participating sites will provide demographics, medical history, CCTA images, FFR-CT (for non-control sites), the decision plan post CCTA and pre FFR-CT (for non-control sites), length of stay for patients in the ED/observation unit/hospital, billing reports (UB-04 preferred), 30-day clinical outcomes, and any other hospital or office visits, imaging, and/or procedural data completed prior to the follow-up 30-day visit. Sites which do not have FFR-CT incorporated into the ED/observation unit will be control sites.
