Stepwise multiple regression analysis of variables associated with cumulative CK release

Dependent variable	Explanatory variable	Standardized regression coefficient	t	p value
Cumulative CK release	Culprit lesion (LAD)	0.20	2.371	0.026
Cumulative CK release	Serum IP-10 levels (before PCI)	− 0.399	− 2.229	0.035

Stepwise multiple regression analysis was performed using the following variables: age, gender, use of ACE/ARB, Ca blocker or aspirin, time to reperfusion, culprit lesion, thrombolysis in myocardial infarction (TIMI) flow grade before primary PCI, collateral flow before primary PCI, TIMI flow grade after PCI, and serum IP-10 level on admission (pg/mL).
