A STUDY ON THE PREVALENCE OF DIPPER AND NON-DIPPER BLOOD PRESSURE BY USING 24 HOUR AMBULATORY BLOOD PRESSURE MONITORING (ABPM) IN HUE UNIVERSITY HOSPITAL

Objectives: To determine the prevalence of dipper and non-dipper blood pressure by using 24 hour ambulatory blood pressure monitoring (ABPM) and to assess the correlation between target organ damage with white coat hypertension and real hypertension. Patients and method: Data from 60 hypertensives including 38 males and 22 females, ages from 25 to 75 yrs were analysed. The 24h ABPM made by German Tonoport’s were used for the measurement of blood pressure with the program 30 minutes per time and ECG and Echocardiography were used to assess the changes in left ventricular structure. Results: - White coat hypertensive group: The prevalence of dipper blood pressure was 43,75% and non-dipper was 56,25%.- real hypertensive group: The prevalence of dipper was 38,64% and non-dipper was 61,36%. There hadn’t the left ventricular hypertropy and lession of ocular fundus in patients who had white coat hypertension. Conclusions: By using the 24 hour ambulatory blood pressure monitoring (ABPM) we can detect the dipper and non-dipper phenomenon of blood pressure
