Clinical outcomes of the patients with early VT/VF or late VT/VF.

Characteristics	Early VT/VF (n=92)	Late VT/VF (n=24)	p value

Length of hospital stay, days	16 ± 29	25 ± 15	0.15
In-hospital recurrent MI, n (%)	2 (2.2)	1 (4.2)	0.51
In-hospital stroke, n (%)	1 (1.1)	1 (4.2)	0.37
In-hospital cardiac mortality, n (%)	22 (24)	14 (58)	0.002
In-hospital noncardiac mortality, n (%)	3 (3.2)	2 (8.3)	0.28
Recurrent MI at 1 year, n (%)	2 (2.2)	1 (4.2)	0.63
Stroke at 1 year, n (%)	3 (3.3)	0 (0)	0.58
All-cause mortality at 1 year, n (%)	26 (28)	17 (71)	< 0.001
Cardiac mortality at 1 year, n (%)	22 (24)	14 (58)	< 0.001

CK: creatine kinase, CK-MB: creatine kinase-MB, MI: myocardial infarction, VT/VF: ventricular tachycardia or ventricular fibrillation.

Note: P value for recurrent MI, stroke, all-cause mortality, and cardiac death were analyzed by log-rank test.
