Microhemodynamics Disorders in the Lung Microcirculatory System in Rheumatoid Arthritis Patients Living in the North Caucasus

Abstract

Rheumatoid arthritis is a systemic autoimmune disease of unknown etiology, characterized by the development of chronic erosive arthritis and systemic inflammatory lesions of the internal organs. A significant number of patients have interstitial lung damage. 70 patients with rheumatoid arthritis were examined. In order to study the hemodynamics of the microcirculatory bed of the pulmonary circulation, the lungs were scanned using a scanner with a Scinticard-Numbering registration system. Blood flow disorders in the microvasculature of the lungs were identified in 67.1 % of patients. The severity of hemodynamic disturbances in the pulmonary capillaries did not depend on the duration of the disease and accompanying pathological processes of the respiratory system. Damage probability for the microvasculature of the pulmonary circulation increases with the degree of disease activity.
