Per-Patient and Per-Vessel Agreement for Detection of Ischemia According to FFRCT at Different Thresholds ≤0.80

Patients
(n = 33)
Vessels
(n = 37)
≤0.8070 (23/33)65 (24/37)

0.71–0.7583 (5/6)75 (6/8)
≤0.70100 (7/7)100 (7/7)

Values are % (n/N). Fractional flow reserve ≤0.80 was used as reference.

FFRCT = coronary computed tomography angiography–derived fractional flow reserve.

  • When comparing per-patient and per-vessel agreement estimates between the lower 3 FFRCT range categories, p values were 0.06 and 0.04, respectively.

  • Two patients (vessels) in whom instantaneous wave-free ratio ≤0.90 was used as the reference standard.
