Clonidine and carotid baroreflex in essential hypertension.
Clonidine is believed to reduce blood pressure by a neural action and animal experiments suggest that this consists in potentiation of baroreflexes. In 16 patients with essential hypertension we studied the effects of alterations in carotid sinus baroreceptor activity (neck chamber technique) on arterial blood pressure (catheter measurements) and heart rate, before and after intravenous adminis...
متن کاملTarget Organ Damage in Essential Hypertension
Epidemiological data suggests that hypertension remains a major modifiable risk factor for cardiovascular disease in Western countries. The prevalence of the disease among adults in Slovenia aged 25–64 years is between 40–50% (CINDI, 2006). The early detection and severity of typical target organ damage and secondary diseases are key determinants of cardiovascular prognosis in patients sufferin...
متن کاملIntrarenal and carotid hemodynamics in patients with essential hypertension.
BACKGROUND The pulsatility index (PI) and resistive index (RI) are used as markers of peripheral vascular resistance. Recently intrarenal PI and RI were introduced for the evaluation of the severity of acute and chronic renal failure, as well as for the diagnosis of renal artery stenosis and kidney graft rejection. In the present study, we evaluated intrarenal PI and RI in patients with essenti...
متن کاملThe common carotid circulation in patients with essential hypertension.
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.
متن کاملHemodynamics of the carotid artery after vasodilation in essential hypertension.
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...
