1. 1. Renal hemodynamics in renal artery stenosis and angiotensin II-dependent hypertension. Pathophysiological and diagnostic aspects

   Författare :Aso Saeed; Göteborgs universitet; []
   Nyckelord :angiotensin II; autoregulation of renal blood flow; color duplex sonography; endothelin-1; oxidative stress; renal artery stenosis; renal hemodynamics; renovascular hypertension;

   Sammanfattning : Patients with renovascular hypertension have a poor renal and cardiovascular prognosis. To improve the care of these patients, we need to increase knowledge about the pathophysiological mechanisms involved. LÄS MER

   Sammanfattning : Background: The measurement of effective renal plasma flow (ERPF) by calculation of p-aminohippurate (PAH) clearance is an invasive, time-consuming procedure. In nonpregnant humans, the clearance of isotopes can be used to measure renal plasma flow, but the use of these radioactive substances during pregnancy is unsuitable. LÄS MER
