Dizziness In The Office Employees With Hypertension, Posturography Reveals Vestibular Trigger

Trinus K, Trinus O

Background: It is widespread opinion that cardiovascular disorders can cause dizziness or vertigo. The evidence basis for this statement is poor. That is why the problem of this presentation is establishing of the relationships between vestibular and vascular dysfunction.
Material and methods: 123 patients (office employees) have been studied, with average age of 52,34±14,82 y.o., out of them 42 males and 81 – females. In 51 persons blood pressure (BP) has been increased. Patients with normal BP have been considered to be control group (n=72). BP measurement at the moment of examination has been performed, as well as posturography with the help of posturographic platform “Micromedical Technologies, Inc.” (USA), sensory organization test (SOT) has been done.
Results: The significant decrease of vestibular function has been found in the hypertensive patients: 88,92±24,91% and 68,29±33,01%, Cd=23,20% (Cd absolute figure is almost the same value as for blood pressure). Difference significance according to F-test ?=0,17, and ?-test ?=0,01. Sway square increase in the hypertensive patient group has been the greatest – from 0,08±0,05 to 0,34±1,00 m2, Cd=325,00%, with difference significance according to F-test ?=1,89?-24, and ?-test ?=0,18, thus manifesting the presence of qualitative, related to hypertension difference between the groups and underlining importance of sway square studies with eyes closed in the patients with arterial hypertension.
Conclusion: Vestibular dysfunction might be among the triggers of hypertension.
