Mean arterial pressure may affect LV mass even when clinic BP is 120/80 mmHg or less.

Detailed echocardiographic evaluation was performed on sixty-four normal persons without any cardiovascular risk factor and clinic blood pressure of 120/80 mm of Hg or less with an aim to find, if there are subclinical echocardiographic changes even in this population. There was significant positive linear correlation between mean arterial pressure and LV mass index. On dividing the patients according to mean arterial pressure, those with mean arterial pressure of more than 85 had significantly higher LV mass index (P <0.01).There may be a relationship between mean arterial pressure and LV mass index in this population, but this needs to be further explored in a larger study.
