Pressure Changes

Continuous blood pressure monitoring in daily life could contribute to early detection of strokes and heart attacks, as well as healthcare promotion. Understanding of what patients were doing when their blood pressure changes occurred would be much more helpful to check the causes of blood pressure changes. However, at present, patients should record their activities by filling the clinical activity record card. The activity record card is so inconvenient that handwriting all the activities becomes a burden and causes inaccuracy. Moreover, it is not able to record posture changes that are a major factor related to short-term blood pressure changes. From these reasons, automatic activities recognition method is strongly required.

Objective.The possible effect of blood pressure measurements per se on heart rate variability (HRV) was studied in the setting of concomitant ambulatory blood pressure monitoring (ABPM) and Holter ECG monitoring (HM).Methods.In 25 hypertensive patients (14 women and 11 men, mean age: 58.1 years), 24-hour combined ABPM and HM were performed. For every blood pressure measurement, 2-minute ECG segments (before, during, and after measurement) were analyzed to obtain time domain parameters of HRV: SDNN and rMSSD. Mean of normal RR intervals (MNN), SDNN/MNN, and rMSSD/MNN were calculated, too. Parameter variations related to blood pressure measurements were analyzed using one-way ANOVA with multiple comparisons.Results.2281 measurements (1518 during the day and 763 during the night) were included in the analysis. Both SDNN and SDNN/MNN had a constant (the same for 24-hour, daytime, and nighttime values) and significant change related to blood pressure measurements: an increase during measurements and a decrease after them (p<0.01for any variation).Conclusion.In the setting of combined ABPM and HM, the blood pressure measurement itself produces an increase in short-term heart rate variability. Clarifying the physiological basis and the possible clinical value of this phenomenon needs further studies.

Safe Medication

The objective of this study is to evaluate the changes of diurnal blood pressure pattern after 8 weeks of red ginseng medication (4.5 g/day) by 24 hour ambulatory blood pressure monitoring. In 26 subjects with essential hypertension, 24 hour mean systolic blood pressure decreased significantly (p = 0.03) while diastolic blood pressure only showed a tendency of decline (p = 0.17). The decrease in pressures were observed at daytime (8 A.M.-6 P.M.) and dawn (5 A.M.-7 A.M.). In 8 subjects with white coat hypertension, no significant blood pressure change was observed. We suggest that red ginseng might be useful as a relatively safe medication adjuvant to current antihypertensive medications.

Diagnosis Of Hypertension

The diagnosis of hypertension in patients on chronic haemodialysis is not easy because the blood pressure changes as a consequence of therapy (haemodialysis) and attenuated circadian rhythm of blood pressure is often present. The estimation of representative blood pressure levels is difficult because it is not known whether blood pressures measured before starting or after completion of haemodialysis are predictive for the average interdialytic blood pressure. Our group of patients consisted of 18 children with endstage renal failure, aged 13.5 ? 3.2 years, treated with chronic haemodialysis from 0.1 to 110 (mean 25.8, median 19) months. Ambulatory blood pressure monitoring was performed during 44h interdialytic period. Blood pressure was also measured with sphygmomanometer before starting and after completion of heamodialysis. The average blood pressure values for the last ten haemodialyses were evaluated as well. Multiregression analysis showed significant correlation between interdialytic blood pressure (systolic and diastolic) and blood pressures measured before haemodialysis (r = 0.74; ? < 0.001, r = 0.78; ? < 0.001, respectively) and after haemodialysis (r = 0.76; ? < 0.01, r = 0.6; ? < 0.05, respectively). Statistically high correlation between these blood pressures was also confirmed for the average blood pressure values for the last 10 haemodialyses (r = 0.78; ? < 0.001, r = 0.75; ? < 0.001 and r = 0.78; ? < 0.001, r = 0.86; ? < 0.001, respectively). Our findings show that blood pressures measured before starting or after completion of haemodialysis give good information about interdialytic blood pressure in children on chronic haemodialysis.
