ABSTRACT
AIM:
To study hemodynamic responses early in the course of active tilt table testing, their correlation with changes in cerebral blood flow in hypertensive patients. MATERIAL ANDMETHODS:
A total of 41 patients with essential hypertension (EH) stage I-II at moderate and high risk (10 males, 31 females aged 48-75 years) were examined using standard clinical and device tests. Ultrasonic investigation of the extracranial arteries was made in duplex scanning regime (Acuson XP 128, USA). To determine initial orthostatic depression reactions we conducted active tilt table testing according to the protocol developed in the department of innovative diagnostic techniques.RESULTS:
In conduction of the modified active tilt table testing 2 types of initial depression orthostatic reaction (OR) were identified with short and long fall of blood pressure. In the latter type BP regressed more (18+/-8 vs 22+/-10), they had more frequent atherosclerosis of extracranial arteries.CONCLUSION:
Hypertensive patients with prolonged initial orthostatic reactions had frequent cerebral hypertensive crises and syncope, initial higher BP, multivessel atherosclerotic lesions of the carotid arteries aggravating cerebral circulation.
