Table 6

Cox analysis independent predictors of 1-year mortality in AMI patients combined with new-onset RBBB.

Value	value	HR (95% CI)
Age	0.009	1.046 (1.011–1.083)
Transient RBBB	0.918	1.092 (0.207–5.768)
ATRBBB	0.041	6.718 (1.084–41.635)
TIT	0.004	1.119 (1.037–1.207)
OMI	0.933	0.937 (0.506–1.807)
Killip ≥ II	0.138	1.969 (0.804–4.820)
CK-MB peak level	0.256	1.002 (0.998–1.006)
LAD as IRA	0.389	0.492 (0.098–2.467)
3-vessel lesion	0.026	4.433 (1.192–16.492)

LAD, left anterior descending branch. IRA, infarction related artery. TIT, total ischemia time. OMI, old myocardial infarction. PCI, percutaneous coronary intervention.
