Overview

May support QFR as FFR alternative in intermediate stenosis; hypothesis-generating, needs prospective validation.

Correlation, agreement, and diagnostic performancesurrogate

QFR demonstrates high diagnostic performance and good agreement with FFR, suggesting it could serve as an alternative for estimating myocardial ischemia in intermediate coronary stenosis.
