Aim To assess the ability of cardiac magnetic resonance (CMR) to exclude prognostically significant coronary artery disease (CAD) in patients with left ventricular systolic dysfunction (LVSD). Materials and methods A cohort of patients who underwent both X-ray angiography and CMR since 2006 was reviewed retrospectively. Records of those with European criteria for LVSD (left ventricular ejection fraction [LVEF] <50% or LV end-diastolic volume index [LVEDVI] ≥97 ml/m2) on CMR or transthoracic echo were analysed. The presence and extent of subendocardial late gadolinium enhancement (LGE) was recorded with the 17-segment model. The degree of coronary stenosis at X-ray angiography was assessed visually and significant disease defined as...
