Abstract

Objectives: The aim of the study was to determine rheoencephalography parameters and some relative factors of abnormal rheoencephalography in patients with hypertension. Materials and methods: A cross-sectional study was carried out in 50 hypertensive patients and 50 healthy ones. Results: The results showed that the crest obtuse wave was 72% and the crest auxiliary wave was 84%. The intensity of cerebral blood flow in hypertensive patients was less than that in normal people (p<0,05). The parameters showed that cerebral blood pressure in hypertensive patients was higher than that in healthy people (p<0,05). In hypertensive patients, the rates of patients who had decreased cerebral blood flow in their arteries were 50%, 48%, and 38%, respectively. The rates of patients who had decreased cerebral blood pressure in their arteries were 54%, 58%, and 58%, respectively. The decreased cerebral blood flow rate in patients who are over 60 years old with dyslipidemia is higher than in the others. Patients with grade III hypertension have a higher decrease in cerebral blood flow intensity and the increased cerebral blood pressure rate compared with grade I hypertension. Conclusions: The decreased cerebral blood flow and the increased cerebral blood pressure in hypertensive patients are higher than that in normal people.
