The common carotid circulation in patients with essential hypertension.
نویسندگان
چکیده
We review carotid artery hemodynamics in hypertensive men, with particular reference to common carotid artery diameter and blood flow, and emphasize the changes in artery diameter and compliance implied by antihypertensive therapy.

Background and purpose : Ârterial embolism is one of the most prevalent cause of transient ischemic attack (TÏÂ) and other types of brain ischemias and about 5o% of TÏÂ patiens have vascular stenosis. Therefore the presence of mild atherosclerotic plaques in carotid arteries, as a source of embdlism in causing TÏÂ and other brain strokes are of a great importance. Ïn present study the ...

Background and purpose: Ischemic brain stroke is one of the most common neurologic diseases and the second cause of death among adults. There is currently no information on the relationship between risk factors influencing anterior and posterior circulation. The most common ischemic strokes occur in the (anterior circulation) AC, while strokes occurring in the posterior circulation (PC) are...
متن کاملProgress Review The Common Carotid Circulation in Patients With Essential Hypertension
Based on the interpretation of several experimental investigations, the study of carotid hemodynamics in hypertension has long been restricted to the pathophysiologic problems related to high-pressure baroreceptors.Indeed, the arterial wall of the carotid bifurcation contains receptors that play a large part in the regulation of blood pressure and that are considered to be reset to higher press...
متن کاملEffect of reflection of arterial pressure on carotid circulation in essential hypertension.
Pressure wave reflection plays a pivotal role in the augmentation of systolic blood pressure. In the present study, the association between reflection of pressure wave and structural and functional alteration, including blood flow, in the common carotid artery was investigated in 70 hospitalized essential hypertensive patients. The reflection of pressure was estimated by the "augmentation index...

We performed simultaneous noninvasive measurements of common carotid artery and brachial artery hemodynamics in nine normal subjects and 10 subjects with sustained essential hypertension. In hypertensive subjects, brachial artery blood flow and forearm vascular resistance were in the normal range while carotid artery blood flow and carotid artery resistance were decreased and increased, respect...
