Abstract
The aim of the present study was to evaluate blood pressure changes (throughout 24-h) by non invasive ABPM as a predictor of LVH in patients with essential hypertension.
Eighty subjects were studied in this study.
•60 hypertensive patients as a test group.
•20 normotensive subjects as a control group.
All subjects were subjected to 24-hours ABPM, ECG and echocardiography.
According to echocardiographic parameters, hypertensive patients were classified into two groups, hypertensives with LVH and hypertensives without LVH. Our study revealed:
•Significant increase in ”LVM” in hypertensive versus normotensive group.
•Ambulatory BP is more closely related to LVM than causal blood pressure.
•Closer relation of systolic over diastolic BP to the degree of hypertrophy, another evidence that wall stress which is mostly related to systolic blood pressure (SBP), is a key factor influencing LVH development.
•Significant increase in left ventricular mass (LVM) in hyprtensives
with marked fluctuations in BP throughout 24-hours versus hypertensives without marked fluctuations.

SUMMARY AND CONCLUSION
■Significant increase in LVM in hypertensive non-dippers versus hypertensive dippers.
■The propensity for LVH among patients with hypertension is increased with age and with the duration of hypertension. In conclusion:
The results underlines the importance of ambulatory blood pressure monitoring (ABPM) in evaluating the effects of hypertension in relation to left ventricular hypertrophy.
