The Value of 24-Hour Ambulatory Blood Pressure Monitoring versus in Office/Home Blood Pressure Measurement in Predicting LV Mass Index in Egyptian Hypertensive Patients on Medical Treatment

Background: One of the outcomes of having chronic hypertension, especially if unrecognized or undertreated is LV hypertrophy (LVH) which is strongly correlated to cardiac morbidity and mortality, apart from the values of blood pressure and existing comorbidities.
Objective: This study aimed at comparing the 24-hour ambulatory blood pressure monitoring vs office/home BP measurement in predicting left ventricular mass in Egyptian hypertensive adults receiving anti-hypertensive medications.
Patients and methods: The present study included 100 known hypertensive patients aged above 18 years. They were on antihypertensive drugs coming for routine follow-up in Ain Shams University outpatient clinics and National Heart Institute between June 2021 and July 2022.
Results: The patients were assigned to 2 groups; group 1 (28 patients) with normal Left ventricular mass index (LVMI) and group 2 (72 patients) with increased LVMI. Female patients had larger LVMI (P < 0.01) and beta blocker users were more in group 2 (P= 0.026). Difference between average home and office blood pressure was not significant between both groups. Control of arterial blood pressure was better in ambulatory blood pressure monitoring in group 1 (P= 0.042). Moreover, 24-hour systolic, average day systolic, diastolic blood pressure, average day pulse pressure as well as reverse dipping had positive correlation with LVMI.
Conclusions: Superiority of ambulatory blood pressure over office and home measurement in predicting LV mass index in Egyptian hypertensive medicated patients.Keywords: Ambulatory Blood Pressure Monitoring; Office Blood Pressure; LV Mass Index; Egyptian Hypertensive
