LV Volumes (Indexed to BSA) and Function by CMR versus Echo. Abbreviations: CMR = cardiac magnetic resonance; echo = echocardiography. Left ventricular end diastolic volume index (LVEDVI), left ventricular end systolic volume index LVESVI), left ventricular stroke volume index (LVSVI), left ventricular ejection fraction (LVEF). Volumes are indexed to body surface area (BSA). Bars represent means, given with standard error whiskers. Comparisons of LVEDVI, LVESVI, and LVSVI between CMR and echo are significant at p < 0.001, and LVEF at p = 0.02.
