1. Introduction
A recent prospective population-based study identified that prolonged QRS duration on resting electrocardiogram (ECG), even if moderate (>110 ms), was related to a higher risk of sudden cardiac death (SCD).1 Furthermore, a substudy of the Oregon Sudden Unexpected Death Study that analyzed the subset of patients with SCD and associated coronary heart disease (CHD), identified prolonged QRS duration as an independent predictor of SCD, irrespective of the presence of prolonged ventricular repolarization.2 In parallel, fragmented QRS (fQRS) has been shown to be a better predictor of perfusion defects and functional abnormalities than the presence of pathological Q waves, and has been identified as an independent predictor of events.3e6 During the past decade, cardiac magnetic resonance (CMR) has become the gold standard to evaluate left ventricular (LV) morphology and function. Several studies have established delayed-enhancement CMR (DE-CMR) as a validated technique to identify and quantify irreversible myocardial damage. LV ejection fraction (LVEF), aside from age, has consistently been identified as one of the most powerful predictors of survival among patients with CHD.7e9 The extent of areas of irreversible myocardial damage detected by DE-CMR has been established as a strong predictor of all-cause mortality or cardiac transplantation, independently from traditional risk factors.10 The relationship between QRS characteristics and myocardial phenotype (LV size, systolic function, and extent of fibrosis) in patients with CHD is not fully understood. We therefore sought to explore this association by means of DE-CMR.
