Blood Flow Characteristics in Rheumatoid Arthritis, Interrelation of Blood Flow Changes with an Endothelium Functional State
76 patients with rheumatoid arthritis have been investigated by means of echography. Endothelium-dependent vasodilation decrease in patients with rheumatoid arthritis was attended with arterial wall elastic properties changes. Significant changes of blood flow in patients with rheumatoid arthritis were found. Peak systolic velocity in medial cerebral artery and resistance index in the main renal artery were increasing, and blood flow velocities at the level of interlobar renal arteries were decreasing. Interrelation of blood flow changes with an endothelium functional state in rheumatoid arthritis are shown.
