Angiographic patterns in vessels according to ICA.

Variables	Mild stenosis	Intermediate	Severe	P-value
		stenosis	stenosis
CTFC (frame)	22.18 ± 7.04	24.22 ± 7.07	24.95 ± 6.84	0.381
PCS (frame)	9.18 ± 2.62	14.91 ± 4.68	20.45 ± 6.13	<0.001
FFR	0.93 ± 0.05	0.83 ± 0.13	0.72 ± 0.18	<0.001

Data are presented as the mean ± SD, CTFC, the corrected TIMI frame count; DS, percent diameter stenosis; FFR, Fractional flow reserve; PCS, CTFC*DS.
