Effectiveness of telemedicine-guided home blood pressure compared to 24 h-ambulatory blood pressure monitoring in patients with and without chronic kidney disease.

Background. Only few direct comparative studies evaluated the effectiveness of telemedicine-guided home blood pressure (tele-HBPM) compared to 24 h ambulatory blood pressure monitoring (ABPM) in assessing blood pressure (BP) and BP control. Material and methods. This prospective clinical trial included patients with arterial hypertension, with (n = 23) and without (n = 18) chronic kidney disease and normal volunteers (n = 16). All subjects underwent with a 1-month interval twice one-week of BP monitoring with office BP (3 measurements at 2 visits), 24 h-ABPM and tele-HBPM during 7 consecutive days. Results. Mean (SD) BP levels were 128/77 [19/11] mm Hg and 126/75 [14/9] mm Hg for tele-HBPM, 129/78 [17/11] mm Hg and 127/75 [14/9] mm Hg for daytime-ABPM, and 133/77 [23/12] mm Hg and 130/74 [17/11] mm Hg for office BP, all respectively at the first and the second measurement periods. Blood pressure and BP control were comparable between the two out-of-office techniques. Conclusion. Both out-of-office techniques (tele-HBPM and 24h-ABPM) show good agreement for systolic as well as diastolic BP, and are equally effective in assessing BP and BP control, explicitly during daytime.
