RCA vs LAD CFR in pulmonary hypertension and RV dysfunction subgroups

	RCA	LAD	p
PSAP ≥ 35 (50 ± 11) mm Hg mean CFR	3.09 ± 0.48	3.10 ± 0.62	NS
RV EF < 0. 35 (0.26 ± 0.06) mean CFR	3.06 ± 0.47	3.22 ± 0.57	NS

It had no difference comparing RCA vs. LAD CFR in pulmonary hypertension and RV dysfunction subgroups.

CFR – coronary flow velocity reserve

RCA – right coronary artery

LAD – left anterior descending coronary artery

PASP – pulmonary artery systolic pressure

RV – right ventricle/ventricular

EF – ejection fraction
