Multivariate analysis of predictors of arrhythmic outcomes.

Factor	Hazard ratio	95% CI	P-value
Composite primary endpoint
Apical HCM	4.58	1.10–10.16	0.04
LV apical aneurysm	3.60	0.43–29.04	0.24
LGE ≥ 15% of LV mass	3.91	1.04–14.74	0.04
Sustained monomorphic VT
Apical HCM	5.17	1.65–16.15	0.01
LV apical aneurysm	4.89	1.20–19.81	0.03
Unexplained syncope	2.63	0.76–9.07	0.13
Family history of unexplained SCD	4.79	1.51–15.19	0.01

LV, left ventricular; LGE, late gadolinium enhancement; SCD, sudden cardiac death.
