Association between late gadolinium enhancement (LGE) and ventricular arrhythmias/sudden cardiac death. LGE was associated with an increased risk for the combined incidence of ventricular arrhythmias, sudden cardiac death, and appropriate implantable cardioverter-defibrillator shocks (odds ratio 4.6; 95% confidence interval [CI] 3.5–6.0; P < .01). Heterogeneity was low to moderate (χ245 = 82.2; P = .001; I2 =45%).
