The Correlation Studies between Ambulatory Blood Pressure Monitoring Parameters and Left Ventricular Hypertrophy in Essential Hypertension

Objective:To study the relationship in the Essential Hypertension (EH) patients of ambulatory blood pressure monitoring index with left ventricular hypertrophy (LVH) , and provide a basis for clinical decision and treatment.Method:Collecting Ningxia Medical University hospital affiliated 90 patients with heart medicine, line echocardiography and 24 hours ambulatory blood pressure monitoring (ABPM), according to the left ventricular weight index (LVMI) was divided into EH with LVH group (n = 37), EH withnot LVH group (n=23) and the control group (n=30), compare the difference between groups, analyze the dynamic blood pressure parameters and LVMI relevance. Result:(1) Systolic blood pressure,night diastolic blood pressure, systolic blood pressure load and LVMI, EH with LVH group was higher than EH without LVH group, EH without LVH group was higher than those in the control group; (2) The correlation between LVMI and systolic blood pressure,diastolic blood pressure, pulse pressure, blood pressure variation,nighttime blood pressure load were positive association, between LVMI and nighttime blood pressure decrease rate was negative correlation.Conclusion:Left ventricular hypertrophy and dynamic blood pressure level, pulse pressure, blood pressure variability and blood pressure load in the night are positively associated,between LVMI and nighttime blood pressure decrease rate is negative correlation.
