The aim of the investigation was to compare a hemodynamic load on the intracranial arterial system assessed by the indices of 24-hours ambulatory blood pressure monitoring and ultrasonography of the large cervical arteries between the group of patients with essential arterial hypertension in 6 months after a hemorrhagic stroke and a group of patients with essential arterial hypertension without complications The first one was the main group n 94 age 54 4 0 9 years m the second one the comparison group n 104 age 53 7 0 9 years The indices of 24-hours ambulatory blood pressure monitoring in the main group and the comparison group were the following the mean daytime systolic blood pressure was 109 6 1 6 and 121 1 1 1 mm Hg the minimal one was 74 4 2 0 mm Hg and 82 3 12 5 mm Hg and the maximal one was 168 2 1 9 and 161 9 1 7 mm Hg p 0 05 The daytime systolic blood pressure sigma 17 9 0 6 and the average real variability of systolic blood pressure 11 31 2 52 mm Hg were bigger in the main group p 0 01 The daytime index of hyperbaric load of systolic blood pressure was bigger in the main group it was 403 6 25 9 against 231 7 12 1 mm Hg h in the comparison group p 0 01 The maximal pulse pressure for a 24-hours interval was 74 2 2 0 and 66 4 0 9 mm Hg respectively p 0 01 The indices of ultrasonography of the large cervical arteries in the right and left vessels of the main group were the following the Gosling s pulsatility index was 1 578 0 059 and 1 552 0 042 for the common carotid artery 1 210 0 044 and 1 102 0 037 for the internal carotid artery 1 191 0 030 and 1 150 0 023 for the vertebral artery The above-mentioned indices were bigger in the main group than in the comparison one p 0 01 The diameters of all the large cervical arteries were bigger in the main group p 0 01 Therefore according to the above-mentioned indices which are associated with a bigger risk of cerebrovascular events a bigger hemodynamic load on the intracranial arterial system was found in the main group than in the comparison one despite the smaller mean systolic blood pressure indices
