Normative data of left ventricular mass index in middle aged population of Vidarbha
Patients with left ventricular hypertrophy (LVH) are more prone to cardio-vascular events than one without LVH. Hence it is important to detect left ventricular hypertrophy at an early stage. Left ventricular hypertrophy denotes increase in mass of left ventricle (LVM). Variety of factors influences left ventricular hypertrophy including various anthropometric parameters. Since LVM is significantly correlated with body surface area (BSA). Left ventricular mass is routinely indexed for body surface area to calculate LVM Index (LVMI). LVMI gives information about presence or absence of left ventricular hypertrophy. In this study 120 normotensive subjects including male and female who were free from any diseases were selected. BSA of participants was measured; the mean value was 1.64 m2. Left Ventricular Mass was estimated by 2-D-Echocardiography, the mean value was 143.38 g. We observed Left Ventricular Mass was significantly correlated with Body Surface Area. Left Ventricular Mass was indexed for Body Surface Areato determines normal range of Left Ventricular Mass using LVM Index. The normal limits of Left Ventricular Mass Index were between 83.95 to 89.69g/m2.
