Key result
Echocardiography shows normal men have ~37% greater LV mass than women despite constant volume/mass ratios.
Why the study?
Defining normal left ventricular mass, volume, and volume/mass ratios by two-dimensional echocardiography was needed to facilitate the noninvasive diagnosis of left ventricular hypertrophy and clarify its relationship with systolic wall stress.
What are the normal ranges for left ventricular mass and volume/mass ratio determined by two-dimensional echocardiography in normal adults?
Observational (n=84)
What are the normal ranges for left ventricular mass and volume/mass ratio determined by two-dimensional echocardiography in normal adults?
p-value: p=<0.001
Two-dimensional echocardiography establishes that while left ventricular mass is higher in men, volume/mass ratios remain constant across sexes, facilitating the noninvasive diagnosis of left ventricular hypertrophy.

Supports sex-specific LV mass norms on echocardiography; leaves open validation with modern 3D/CMR methods in diverse cohorts.
BYRD et al. (1985) conducted an observational in Normal adults (n=84). Two-dimensional echocardiography was evaluated on Left ventricular mass and volume/mass ratio (p=<0.001). Two-dimensional echocardiography showed left ventricular mass was larger in normal men than women (148 vs 108 g, p<0.001), while volume/mass ratios were constant at end-diastole and end-systole.
