Univariate and stepwise multivariate cox regression analysis for the prediction of MACEs.

Variate	Univariate		Multivariate
	Hazard ratio (CI)	p-value	Hazard ratio (CI)	p-value
EF, (%)	0.862 (0.789–0.943)	0.001	0.874 (0.775–0.985)	0.027
Infarct size, (% LV)	1.093 (1.038–1.150)	0.001	1.031 (0.961–1.106)	0.393
Area at risk, (% LV)	1.007 (0.961–1.056)	0.767	–	–
Reperfusion time, (min)	1.003 (0.999–1.007)	0.169	–	–
MSI, (%)	0.908 (0.861–0.958)	0.000	0.926 (0.875–0.980)	0.008

P < 0.05 is considered to indicate statistical significance. MACE, major adverse cardiovascular events; EF, ejection fraction; MSI, myocardial salvage index.
