Noninvasive FFR Derived From Coronary CT Angiography: Management and Outcomes in the PROMISE Trial.

ABSTRACT:

Objectives

The purpose of this study was to determine whether noninvasive fractional flow reserve derived from computed tomography (FFR_CT) predicts coronary revascularization and outcomes and whether its addition improves efficiency of referral to invasive coronary angiography (ICA) after coronary computed tomography angiography (CTA).

Background

FFR_CT may improve the efficiency of an anatomic CTA strategy for stable chest pain.

Methods

This observational cohort study included patients with stable chest pain in the PROMISE (PROspective Multicenter Imaging Study for Evaluation of Chest Pain) trial referred to ICA within 90 days after CTA. FFR_CT was measured at a blinded core laboratory, and FFR_CT results were unavailable to c
