| Description | Reproducibility of relationship between carotid intima-media thickness (IMT) and baroreflex sensitivity (BRS) was studied in normotensives and hypertensives with respect to the signs of tonic and reflex autonomic control of heart rate and blood pressure (BP). After one year, SBP measured by Finapres decreased by 9 mmHg (p<0,05) in Nnorm. In Hy, ABP values decreased - DBP during day by 4 mmHg (p<0.05), mean DBP in 24h by 3 mmHg (p<0.05), and Finapres values as well - SBP by 13 mmHg (p<0.01), DBP by 12 mmHg (p<0.05), variability of SBPsd decreased by 1 mmHg (p<0.05), of DBPsd by 0,5 mmHg, (p<0,05), but variability SBPrel increased by 0,023 r.u. (p<0,05). 24-h index variability of IBI SDANN decreased by 22 ms (p<0,01). Other parameters were unchanged after one year. A mild decrease of BP, a decrease of short-term blood-pressure variability and the increase of the power in spectra of SBP into range of 0.1 Hz is a positive effect of the therapy. |
