Multivariate analyses of predictors for cardiac mortality and MACE-free survival of patients with CTO.

Variable	HR (95% CI)	𝑃 value
MACE
CTO-PCI successful	0.58 (0.32–0.94)	<0.01
Prior MI	3.89 (1.95–7.84)	<0.05
CKD	3.51 (1.52–7.87)	<0.01
LVEF (per-10% increment)	0.94 (0.88–0.99)	<0.05
Mortality
CTO-PCI successful	0.35 (0.19–0.68)	<0.01
Age	1.08 (1.02–1.11)	<0.01
Prior MI	2.31 (0.73–7.35)	0.16
CKD	7.18 (2.95–17.40)	<0.01
LVEF (per-10% increment)	0.87 (0.77–0.93)	<0.01

CI: confidence interval; HR: hazard ratio; CTO: chronic total occlusion; PCI: percutaneous coronary intervention; MI: myocardial infarction; CKD: chronic kidney disease; LVEF: left ventricular ejection fraction.
