The relationship between left ventricular hypertrophy of essential hypertension and blood pressure variability

Objective To investigate the relationship between left ventricular hypertrophy(LVH) and blood pressure variability(BPV) in essential hypertension patients.Methods Sixty-eight cases of patients with essential hypertension were divided into LVH and non-LVH group according to left ventricular mass index(LVMI).Using 24-hour ambulatory blood pressure monitoring device,BPV was measured by the standard deviation in each period(day,night and 24-hour).The relevance between IVH and BPV was explored.Results Systolic blood pressure in different period in LVH group was significantly higher than in non-LVH group.There was statistically significant differences in variability of dSSD,dDSD,nSSD,nDSD,24hSSD between the LVH group and the non-LVH group(P 0.05).There was a good correlation between BPV and LVMI.Conclusion There is a close relationship between BPV and LVH in patients with essential hypertension,especially in systolic blood pressure.
