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

Introduction Only few direct comparative studies evaluated the effectiveness of telemedicine-guided home blood pressure (tele-HBPM) compared to 24h ambulatory blood pressure monitoring (ABPM) in assessing blood pressure (BP) and BP control. 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), 24h-ABPM and tele-HBPM during 7 consecutive days. Results Mean+-SD BP levels were 128/77+-19/11 mmHg and 126/75+-14/9 mmHg for tele-HBPM, 129/78+-17/11 mmHg and 127/75+-14/9 mmHg for daytime-ABPM, and 133/77+-23/12 mmHg and 130/74+-17/11 mmHg 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.
