Establishes that normal LV volume and mass differ by sex and ethnicity, highlighting the need to account for these variations in cardiovascular risk assessment.
Sex- and ethnicity-specific LV norms may refine assessment; extends reference data but requires prospective validation before practice change.
The normal LV differs in volume and mass between sexes and among certain ethnic groups. When indexed by body surface area, LV mass was independent of age for both sexes. Studies that assess cardiovascular risk factors in relationship to cardiac function and structure need to account for these normal variations in the population.
