Abstract excerpt
BACKGROUND: Left ventricular hypertrophy (LVH) is traditionally classified as concentric or eccentric, based on the ratio of LV wall thickness to chamber dimension. We propose a 4-tiered LVH classification based on LV concentricity(0.67) (mass/end-diastolic volume(0.67)) and indexed LV end-diastolic volume (EDV). METHODS AND RESULTS: Cardiac MRI was performed in 2803 subjects and LVH (n=895) was defined by...
