Increasing Left Ventricular Mass and Death in Men and Women Investigated With Echocardiography.

ABSTRACT:

Background

Left ventricular hypertrophy (LVH) categories are based on left ventricular mass index (LVMi). This study aimed to generate and externally validate sex-stratified LVMi cutoffs according to incremental mortality risk.

Methods

LVH information was determined on 155 668 men (aged 61.3±17.3 years) and 147 880 women (61.8±18.3 years) from the National Echocardiography Database of Australia. Sex-specific mild to severe thresholds of the increasing 5-year mortality rate based on LVMi increments were generated. These new thresholds were then validated in a US Medicare-linked echocardiographic database.

Results

In the National Echocardiography Database, 36198 men (23.3%) and 38 898 women (26.3%) had LVH, with an actual 5-year mortality rate of 38.3% and 31.2%, respec
