The Importance of Home Versus 24-Hour Ambulatory Blood Pressure Monitoring and Assessment of Blood Pressure Variability in Hypertension

DOI: 10.1515/amma-2016-0020

Background: A number of studies reveal that home blood pressure variability is associated with cardiovascular risk factors. However, we do not have a consensus regarding the variability index and the frequency of measurements.
Objective: The aim of the study was to assess home blood pressure variability for a period of 7 consecutive days and 24-hour ambulatory blood pressure variability using the average real variability index and to test whether home blood pressure variability represents a suitable parameter for long-term monitoring of the hypertensive patients.
Material and methods: A number of 31 hypertensive patients were included in the study, 8 male, 23 female, mean age 60.19±7.35 years. At the inclusion ambulatory blood pressure monitoring was performed, home blood pressure monitoring was carried out for 7 consecutive days with 2 measurements daily. We compared ambulatory blood pressure values, variability using paired t-test. We were looking for correlations between HBP values and cardiovascular risk factors.
Results: Ambulatory versus home blood pressure derived mean blood pressure was 131.38±15.2 versus 131.93±8.25, p=0.81. Ambulatory derived variability was 10.65±2.05 versus home variability 10.56±4.83, p=0.91. Home versus ambulatory pulse pressure was 51.8± 9.06 mmHg vs. 54.9±11.9 mmHg, p=0.046. We found positive correlation between HBPV and home BP values, p=0.027, r2=0.1577, (CI: 0.04967 to 0.6588). Home, as well as ambulatory derived variability were positively correlated to age p=0.043, r2=0.1377 (CI: 0.01234 to 0.6451) versus p<0.0001, CI: 0.3870 to 0.8220, r2=0.4302.
Conclusion: Assessment of home blood pressure monitoring and variability could represent a well-tolerated alternative for long-term follow-up of hypertension management.

Ambulatory Blood Pressure and Arterial Stiffness in Obese Children and Adolescents

DOI: 10.1515/amma-2015-0090

The aim of the present study was to investigate differences regarding 24-hour blood pressure and arterial stiffness in a cohort of office normotensive obese and non-obese children and adolescents, and to evaluate correlations of these parameters with some anthropometric indices.
We retrospectively evaluated ABPM records in 71 children (42 boys); 31 obese compared with 40 normal-weight children.
Results: Mean 24-hour, day-time and night-time SBP was significantly higher in the obese group than in the control group (p <0.01 during the entire period). Significantly higher AASI values were found in obese children compared to controls (0.45 vs. 0.41, p <0.05), the difference being more obvious for day-time AASI (p <0.001). Conclusions: This research confirms that SBP and AASI are increased in obese children. AASI is a useful index of arterial stiffness that can be easily measured under ambulatory circumstances in children.
