Table 5

Independent predictors of early (0–30 days) and late (30 days–3 years) mortality.

Variable	HR (95% CI)	𝑃 value
Predictors of overall 3-year mortality
Shock on admission	4.6 (3.5–6.7)	<0.01
MVD with CTO	2.3 (1.5–2.8)	<0.01
CrCL < 60 mL/min	1.6 (1.1–2.2)	<0.05
History of prior MI	1.6 (1.1–2.3)	<0.05
History of congestive heart failure	2.8 (1.7–4.7)	<0.01
LAD-related MI	2.1 (1.6–2.8)	<0.01
TIMI flow 3 post-PCI	0.6 (0.4–0.8)	<0.01
Predictors of 30-day–3-year mortality
Shock on admission	2.1 (1.2–2.9)	<0.05
MVD with CTO	1.9 (1.4–3.6)	<0.01
MVD without CTO	1.1 (0.8–1.6)	0.50
History of congestive heart failure	2.6 (1.4–4.5)	<0.01
LAD-related MI	1.9 (1.5–2.4)	<0.01
Predictors of 30-day mortality
Shock on admission	7.8 (5.9–9.8)	<0.01
MVD with CTO	3.4 (2.4–4.5)	<0.01
MVD without CTO	1.7 (1.3–2.3)	<0.05
LAD-related MI	1.5 (1.2–1.8)	<0.05
TIMI flow 3 after PCI	0.5 (0.3–0.8)	<0.01

CI: confidence interval; HR: hazard ratio; MVD: multivessel disease; CTO: chronic total occlusion; CrCL: creatinine clearance; LAD: left anterior descending coronary artery; MI: myocardial infarction; TIMI: thrombolysis in myocardial infarction; PCI: percutaneous coronary intervention.
