Fractional Flow Reserve and Fractional Flow Reserve Gradient From CCTA for Predicting Future Coronary Events.

ABSTRACT:

Background

Coronary computed tomography angiography-derived fractional flow reserve (FFR_CT) is a per-vessel index reflecting cumulative hemodynamic burden while coronary events occur in focal lesions.

Objectives

The authors sought to evaluate the additive prognostic value of the local gradient of FFR_CT (FFR_CT gradient) in addition to FFR_CT to predict future coronary events.

Methods

The current study included 245 patients (634 vessels) who underwent coronary computed tomography angiography within 6 to 36 months before the index angiography, of which 209 vessels had future coronary events and 425 vessels did not. Future coronary events were defined as a composite of vessel-specific myocardial infarction or urgent revasculariza
