Evaluation of the Effect of Concurrent Chronic Total Occlusion and Successful Staged Revascularization on Long-Term Mortality in Patients with ST-Elevation Myocardial Infarction

Table 4

Overall 3-year clinical outcomes in patients with CTO of attempted recanalization of a CTO in the non-IRA.

Variable	CTO-PCI		𝑃 value
	Successful (𝑛 = 100, 67.6%)	Failed (𝑛 = 48, 32.4%)
MACE	28 (28.0%)	24 (50.0%)	0.009
Death	11 (11.0%)	12 (25.0%)	0.028
Cardiac	9 (9.0%)	11 (22.9 %)	0.020
Noncardiac	2 (2.0%)	1 (2.1%)	0.973
Ischaemia-driven target vessel
Revascularization	15 (15.0%)	12 (25.0%)	0.140
Rehospitalization due to
heart failure	9 (9.0%)	11 (22.9%)	0.020
Stroke	3 (3.0%)	2 (4.1%)	0.713
Reinfarction	9 (9.0%)	6 (12.5%)	0.509

Categorical variables are described as absolute numbers (%) and compared by means of the chi-square test. CTO: chronic total occlusion; PCI: percutaneous coronary intervention; MACE: major adverse cardiac events.
