Early repolarization pattern (ERP) is associated with ventricular fibrillation in patients without structural heart diseases. Moreover, ERP was reported to be associated with SCD in patients with old myocardial infarction in a case\u2010control study. However, little information is available on the prognostic significance of ERP in CHF patients. Thus, we aimed to investigate whether ERP is associated with SCD in CHF patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>The study population consisted of 132 consecutive outpatients with NYHA class I, II and III congestive heart failure and radionuclide left ventricular ejection fraction less than 40%. All patients underwent the standard 12\u2010lead electrocardiogram at enrollment, where we assessed the presence of ERP using the criteria of J\u2010point elevation \u2265 0.1 mV in at least 2 inferior or lateral leads. The primary endpoint of this study was SCD. At enrollment, 16 patients had ERP. During the follow\u2010up period of 6.7 \u00b1 3.5 years, 26 patients had SCD. Kaplan\u2013Meier analysis showed that SCD was observed significantly more frequently in patients with ERP than in those without ERP (63% [10\/16] vs 14% [16\/116], P &lt; 0.0001]. A multivariate Cox analysis revealed that ERP was significantly and independently associated with SCD (hazard ratio, 3.7; 95% confidence interval, 1.6\u20138.6; P\u00a0= 0.002).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>ERP in inferior leads would be associated with an increased risk of SCD in CHF
