Features of blood flow velocity and intima-media thickness of peripheral arteries in idiopathic arterial hypotension in young women
Two groups of patients (age 18-25 years) were examined: 73 women with idiopathic arterial hypotension (SBP 90-98 mmHg) and 37 women with normal arterial pressure (SBP 120-129 mmHg). A comparative analysis of the thickness of the intima-media (IMT) and the integral of linear flow velocity in symmetric vessels was performed: vertebral, internal carotid, brachial, radial, posterior tibial arteries. It was revealed that, with hypotension, the blood flow velocity in the vertebral and internal carotid arteries was reliably higher by 11%-15% than at normal arterial pressure. There were no differences in the IMT between the study groups, no cases of IMT 1.0 mm or more, which indicates the absence of signs of early atherosclerosis in young women with idiopathic arterial hypotension.
