Improving the poor diagnostic accuracy of the ECG at detecting prognostically significant left ventricular hypertrophy in hypertensive patients
Journal of Cardiovascular Magnetic Resonance(2015)
Abstract
Background Normalised left ventricular mass (LVM) is a powerful prognostic tool. Traditionally, normalising has been achieved by indexing LVM to body surface area (BSA). A recent ‘Multiethnic Study of Atherosclerosis’ (MESA) sub-study demonstrated indexing LVM to height is more sensitive at identifying left ventricular hypertrophy (LVH) associated with cardiovascular events and all-cause death. We evaluated the ability of the ECG, an universal investigation in patients with hypertension, to detect LVH defined traditionally by LVM/BSA and by the prognostically more important LVM/height method using CMR (non-invasive gold-standard for LVM).
