Abstract

V originále

Objective: Co assess the Orcadian and half-weekly variability of 7-da\ 24-hour ambulatory blood pressure (BP) and heart rale (HR) monitoring. Design and method: Hundred and thirty men and fifty-seven lemales without antihypertensive therapy (age between 20 and 80 years) were recruited for 7-day ambulatory BP monitoring (TM-2421 A and D, Japan). The obtained data were fitted with sinusoid curve (wave length 24 hours) by the least square method and mean value (M) and amplitude (A) were determined for every subject Double amplitude roughly corresponds to the night-day BP difference Results: BP overswingmg (excessive dipping, circadian hyper-amplitude-tension). a vascular disease risk factor was detected in 8.5co SBP and 7 0% SBP and DBP BP overswinging vvas associated with evening exercise in one subject. Decreased heart rate vanabilily oceuircd in 2.2%. In the data from the whole group, women had a lower SBI'-Ivl (p 0 026) and a higher HR-M (p-^0 005) than men SBP increased linearly with age (r"0.341, p<0 001) The M of DBP and HR and the circadian amplitudes of SBP and DBP followed a quadratic model, reaching maximum values around 40-60 years of age.
