Twenty-four-hour ambulatory blood pressure in men and women aged 17 to 80 years: the Allied Irish Bank Study

Reproducibility of ambulatory blood pressure monitoring in daily practice

“…The mean day-night difference during the two ABPM recordings using the definition of a long period is given in Table 2. Using a definition of a shorter day-and night-time period, or using the definitions as reported in the literature, 16,17 did not affect the mean difference between the day and night blood pressures significantly (Table 3). The number of dippers was 28 (62%) during the first and 27 (58%) during the second ABPM recording (Table 3).…”

“…In addition, we analysed the data using two different definitions that have been reported in the literature. 16,17 …”

Effects of age and gender on ambulatory blood pressure and heart rate

“…A comparison of ambulatory BP values for subjects between the ages of 17-29 years reveals similar levels as the young group in the present study. 4 It seems probable that the excellent health status and health habits, such as regular exercise, practiced by the elderly group influenced age-related changes in BP, thus accounting for a smaller increase in BP in elderly women. These results seem to indicate that when people are free of health problems, age is less likely to be associated with an increase in BP.…”

“…1 On the other hand, studies investigating the relationship between age and ambulatory BP have yielded conflicting findings, ranging from no change in BP to moderately higher BP as a function of age. [2][3][4][5][6][7] The relationship between gender and age-related BP changes is unclear, as most studies do not report on the association between these variables. In a meta-analysis of 23 ambulatory studies including subjects between the ages of 17-80, Staessen and colleagues 8 reported that SBP increases on the average 2.8 mm Hg per decade in women, but only 0.2 mm Hg per decade in men, whereas DBP increases 1.1 mm Hg per decade in both men and women.…”

Vascular and neuroendocrine components in altered blood pressure regulation after surgical repair of coarctation of the aorta

“…as the norm, four of the 20 patients examined had an increased SAP and three (including two of the above four patients) an increased DAP. 19 One of these five patients, treated with a calcium antagonist because of an ischaemic cardiopathy, also had increased sphygmomanometric brachial arterial pressure. Contrary to this, six of the 15 patients with normal BP values had increased sphygmomanometric brachial arterial pressure; the sphygmomanometric DAP of three of them was also increased.…”
