Abstract
Objective: Ambulatory blood pressure monitoring (ABPM) plays an important role in monitoring the effectiveness of antihypertensive treatment. It enables to obtain clear information about absolute values and variability of blood pressure in time-defined periods. The aim of our work was to evaluate the clinical benefit not only from the point of view of BP control, but also from the prognostic aspect by determining the diurnal index. Design and method: To control the effectiveness of antihypertensive treatment, we used ABPM - Cardiosoft-Tonoport V, General Electric (USA) with oscillometric blood pressure measurement. We analyzed 206 ABPM records in hospitalized patients. There were 93 men (45%) and 113 women (55%). The monitored group of patients was divided into 4 groups according to age. There were 31 persons in the age group of 18-44 years, 78 persons in the age group of 45-64 years, 52 persons in the age group of 65-74 years and 45 persons in the oldest age group (75 years and over). In 15 patients (7.3%), we did not determine the diurnal sign for night waking. Results: The group of dippers consisted of 79 people (38.3%), there were also 79 people (38.3%) in the group of non-dippers, there were 30 risers (14.6%) and 3 extreme dippers (1.5%). Following the further fate of the investigated persons, we found that 19 persons (9.2%) died within 2 years, of which 14 were from groups with a disturbed diurnal index (9 non-dippers and 5 risers). Conclusions: Our results point to the fact that in addition to the basic parameters of BP used as an indicator of blood pressure control, the analyses of diurnal character disturbances has a importance in prognostic aspect. Identifying these patients may therefore be helpful in the management of hypertension and comorbidities.
