The 11-Year Prognostic Impact of Chronic Total Occlusion in the Noninfarct-Related Coronary Artery on Patients with Acute Myocardial Infarction

Table 4

Multivariable regression model of all-cause MACCE during the entire follow-up period in the whole study population (only showing CTO in the non-IRA and other variables with statistical significance).

Variable	Coefficient	Standard error	HR	95% CI; lower limit	95% CI; upper limit	value
CTO in the non-IRA	−0.23471	0.137333	0.790799	0.604182	1.035057	0.087438
LVEF by echocardiography	−0.01565	0.005328	0.984467	0.974241	0.994801	0.0033
In-hospital MACCE	0.615082	0.23046	1.849808	1.177493	2.905996	0.007609
Two-vessel disease	0.300066	0.132752	1.349948	1.040683	1.75112	0.023799
Three-vessel disease	0.463517	0.123943	1.589655	1.246815	2.026767	0.000184

In Table 4, we discovered in-hospital MACCE, two-vessel disease, and three-vessel disease were independent predictors of 11-year MACCE in the entire study population. LVEF remained as a protective factor for survival.
