Abstract

Objectives: Survey on the characteristics of cerebral blood flow in elderly hypertensive patients with vertigo at Hue Central Hospital. Materials and methods: The study was conducted on 183 elderly inpatients at the Department of General Internal Medicine - Geriatrics, Hue Central Hospital, with a cross-sectional descriptive study. Results: The most common age group was 70-79 years (43.2%), with an average age of 74.09±7.96 years. The female-to-male ratio was 2.2. The highest percentage of blood pressure classification was in the well - controlled blood pressure group, with 42.1%. The rate of increased vascular tone in the mastoid occipital lead (67.2%) was higher than in the frontal mastoid lead (51.9%), while the rates of decreased blood flow intensity in both leads were nearly similar, at 32.8% and 39.9%. Regarding traditional medicine's clinical classification of hypertension, most patients belonged to the yin deficiency of the liver and kidney type (44.3%) and the phlegm - dampness type (30.6%), with the lowest being the dual deficiency of yin and yang type (7.1%). Conclusion: Characteristics of cerebral hemodynamics in elderly hypertensive patients with dizziness include increased vascular tone in both the frontal - mastoid and mastoid - occipital leads. The most commonly encountered clinical syndrome is liver and kidney yin deficiency with phlegm - dampness.
