Key result
Among Japanese patients with normal LVEF, women had a significantly faster E wave (79 vs 69 cm/s), longer ejection time, and smaller Tei index (0.38 vs 0.44) than men (all p<0.005).
Why the study?
Are there gender differences in left ventricular diastolic and systolic echocardiographic parameters among healthy Japanese subjects?
Cross-Sectional (n=163)
Are there gender differences in left ventricular diastolic and systolic echocardiographic parameters among healthy Japanese subjects?
Significant gender differences exist in normal left ventricular echocardiographic parameters, including E wave, ejection time, Tei index, and LV mass index, which should be considered when evaluating cardiac function.
Sex-specific echo reference values may refine interpretation in Japanese adults with normal LVEF; leaves open prognostic or therapeutic relevance.

Kondo et al. (2007) conducted a cross-sectional in Normal left ventricular ejection fraction (n=163). Female sex vs. Male sex was evaluated on Echocardiographic parameters of left ventricular function (E wave, Tei index, LV mass index) (p=<0.005). Among Japanese patients with normal LVEF, women had a significantly faster E wave (79 vs 69 cm/s), longer ejection time, and smaller Tei index (0.38 vs 0.44) than men (all p<0.005).
