A Vascular Abnormality in Hypertension
T HE increased peripheral resistance associated with hypertension has been demonstrated for the circulation as a whole by measurements of blood pressure and cardiac output.l 2 The site of this resistance has not been precisely identified but it is believed to reside in the smallest arteries and arterioles.3'4 Since the activity of the smooth muscle in these vessels is readily affected by humora...
متن کاملDiminished finger volume pulse in borderline hypertension: evidence for early structural vascular abnormality.
Digital volume pulse maximum dilation was determined in 27 patients with borderline essential hypertension (BHT) and 28 age-matched normotensive controls (NT). Finger pulse volume (PV) and finger systolic pressure (SBP) were measured by pneumoplethysmography during vasodilation induced by combining direct and reflex heat dilation and reactive hyperemia. Finger SBP was higher (p less than 0.01) ...
متن کاملMoyamoya-like vascular abnormality in pulmonary sarcoidosis.
Cigarette smoking, alcohol ingestion and any regular medications including birth control pills were denied. Family history of stroke was also denied. Physical and neurological examination revealed no abnormal signs except for bilaterally decreased superfi cial sensation in the distribution from the right 2nd thoracic and left 8th cervical to bilateral 2nd lumbar segments. Laboratory results rev...
متن کاملArterial vascular abnormality accompanying cerebral cortical dysplasia.
We report a case of dysplastic arterial vascular abnormality in a 32-year-old man with overlying neuronal cell migration disorder. MR images showed a thickened left insular cortex adjacent to the abnormal vascular network. These findings suggest the possibility of leptomeningeal damage during neuronal cell migration as the cause of the overlying vasculopathy. The true pathogenesis of these seem...
متن کاملStructural Abnormality or Vascular Dysfunction? A Road to Ruin
Changes in vascular function and structure of vessels are evaluated by flow-mediated vasodilation (FMD) and intima-media thickness (IMT), respectively , which are surrogate markers for atherosclero-sis 1-3). Increased IMT of the carotid artery and impaired brachial FMD are indeed prevalent in patients with a high risk of cardiovascular diseases, such as those with diabetes, dyslipidemia, and hy...
