MARTINEZ GONZALEZ, Aniley; LEON ALVAREZ, Jorge Luis e MARCOS GUTIERREZ, Yamilé. Basal diameter of brachial artery when assessing patients with essential hypertension. Rev cubana med [online]. 2020, vol.59, n.2 Epub 01-Jun-2020. ISSN 1561-302X.
Introduction:
The most prevalent cardiovascular diseases and high blood pressure are supported by atherosclerosis and endothelial dysfunction. The non-invasive assessment of subclinical atherosclerosis complements the cardiovascular risk stratification when evaluating hypertensive patients.
Objective:
To determine the value of the basal diameter of the brachial artery in assessing patients suffering from essential arterial hypertension.
Method:
An analytical cross-sectional study was carried out in 30 patients with essential arterial hypertension. They underwent ultrasonography to measure the basal diameter of the brachial artery, endothelium-dependent vasoreactivity and carotid mean intima thickness, as well as the cardiovascular risk, time of evolution and degree of arterial hypertension. Statistical tests such as one-way ANOVA and Pearson's correlation coefficient were used to determine the association between arterial diameter and the rest of the variables.
Results:
Endothelial dysfunction was present in 83.3% of the studied patients. Both the thickness of the carotid media intima complex and endothelium-dependent vasoreactivity were adequate markers for atherosclerotic disease. The basal diameter of the brachial artery had inverse correlation with endothelium-dependent vasoreactivity, and it showed expected mean values in relation to the presence of smoking, and with the worst degrees of hypertensive disease and cardiovascular risk.
Conclusions:
The basal diameter of the brachial artery did not show the expected association for the evaluation of essential hypertensive patients in the studied population.
