['Left ventricular late gadolinium enhancement (LV-LGE) by cardiac magnetic resonance (CMR) imaging has been associated with adverse clinical outcomes in patients with non-ischemic cardiomyopathy (NICM). However, an association between the characteristics of the LGE and arrhythmic risk has not been demonstrated consistently. This study evaluated the impact of the LV-LGE characteristics on the arrhythmia risk in patients with NICM.', 'This study enrolled 365 consecutive patients (54±15years) with NICM who underwent CMR imaging. All patients were monitored for the following outcomes: major arrhythmic events (MA), including sustained ventricular tachycardia, an appropriate implantable cardioverter-defibrillator intervention, ventricular fibrillation and sudden cardiac death.', 'During 44.3±36.4months of follow-up, 44 (12.1%) patients experienced MA. LV-LGE was observed in 40 (90.9%) and 221 (68.8%) patients with and without MA, respectively. LV-LGE was more frequently observed in the MA group (p=0.002). The age- and sex-adjusted hazard ratio (HR) of MA was increased in patients with LGE extent≥8% (HR 8.45, 95% confidence interval (CI) 2.91-24.6), and those with subendocardial (HR 6.98, 95% CI 1.74-28.0) and subepicardial LGE patterns (HR 7.2, 95% CI 1.61-35.6). In multivariable models adjusted for other clinical variables, only the subepicardial LGE pattern had 7.2 (95% CI, 1.61-32.6, p=0.01) time increase in the MA risk.'] Does pattern of late gadolinium enhancement predict arrhythmic events in patients with non-ischemic cardiomyopathy?
