A blood pressure has caused a lot adverse effect to the body and as a whole society if it remains untreated. Hypertensive state causes increase in left ventricular diameter as well as mass. These two conditions can be also called as LV hypertrophy. Method: 60 male individuals aged from 35 to 45 years enrolled in the study from Dhiraj general hospital after getting ethical approval. Their general examination and history was taken after that blood pressure was recorded. Participants were divided in 4 groups based on JNC guideline. 2 D echocardiography was performed and Left ventricular mass (LVM) recorded. Left ventricular mass index (LVMI) was calculated after getting body surface area (BSA). Result: Blood pressure changes show marked variation in Left ventricular mass as well as Left ventricular mass index. Pre hypertensive and hypertensive stage 1 and stage 2 shows marked rise in LVM in comparison with normotensive individuals. Blood pressure is positively correlated with left ventricular mass and also with ventricular mass index. Out of all 4 groups Prehypertensive stage shows more risk for LVM and LVMI. Conclusion: There is multifold rise in LVM and LVMI when blood pressure increased from normal range. The left ventricular hypertrophy has one independent factor above other confounding factors.
