AbstractElectrocardiographic left ventricular hypertrophy (L VH) has been a bad prognostic factor
for cardiovascular morbidity and mortality. However the prevalence and prognostic value of
LVH are varied among nationalities and populations. Several factors have been shown to associate
with LVH. Some factors are treatable such as hypertension. We prospectively studied the preva-
lence of LVH and associated factors in selected group of Thai population. The study population
was I ,606 Shinawatra employees who were 30 year old or more. The prevalence of L VH was 13
per cent (210) among study population. Hypertension, lower body weight and male sex were sig-
nificantly associated factors. In the subjects with LVH, the prevalence of hypertension was 25.6
per cent, male ratio was 5:1 and mean body weight was 57.7 kg. compare to 9.8 per cent preva-
lence of hypertension, 2: I female ratio and mean body weight was 62.3 kg in the group without
LVH.
