Comparison of Clinical Outcomes Among 4 Groups Classified by LVEF and CFR

Clinical outcomes	CFR>2.0		CFR ≤2.0		P value*
	LVEF ≥50% (n=1602)	LVEF <50% (n=119)	LVEF ≥50% (n=688)	LVEF <50% (n=83)
Target vessel failure	89 (7.2%)	12 (13.1%)	73 (14.2%)	11 (17.4%)	<0.001
All‐cause death	38 (3.3%)	7 (8.3%)	42 (8.1%)	7 (11.8%)	<0.001
Cardiac death	28 (2.4%)	6 (6.8%)	29 (6.2%)	4 (7.1%)	<0.001
Target vessel myocardial infarction	17 (1.4%)	3 (3.7%)	11 (2.2%)	7 (11.1%)	<0.001
Target vessel revascularization	60 (4.8%)	6 (6.8%)	56 (10.8%)	3 (5.2%)	<0.001

CFR indicates coronary flow reserve; and LVEF, left ventricular ejection fraction.
