Does a hybrid resting full-cycle ratio and fractional flow reserve strategy reduce the requirement of vasodilator administration while maintaining agreement with an FFR-only strategy in patients with non-ST elevation acute coronary syndrome?
A hybrid RFR-FFR strategy maintains high diagnostic agreement with FFR alone while reducing the need for vasodilators by over 50% in NSTE-ACS patients.
Resting full-cycle ratio and FFR have high correlation and consistency. The hybrid RFR-FFR strategy highlights considerably enhanced agreement with the FFR-only strategy, whilst making the requirement of vasodilator administration less than a half.
