title: [Morphologic festures of cardiac lesions in rheumatoid arthritis].
abstract: Morphological examinations of the heart in cases of articulo-visceral rheumatoid arthritis revealed in 20 of the 35 conducted observations certain changes attributable to the underlying disease. The following groups of changes were revealed: 1) endocarditis; 2) myocarditis; 3) pericarditis; 4) rheumatoid nodules; 5) valvular sclerosis and mural endocarditis; 6) cardiosclerosis; 7) amyloidosis; 8) coronaritis and coronary sclerosis; 9) adhesions in the pericardial cavity. The severity of cardiac leasion in rheumatoid arthritis is determined by the involvement of the serosa into the pathological process. Inflammatory and sclerotic changes in the myocardium are predimonantly of a subepicardial and subendocardial nature, usually non-accompanied by any clear clinical symptoms, or taking a latent course. Rheumatoid nodules typical of rheumatoid arthritis, and deposits of amyloid masses in the walls of the coronary arteries are noted rarely. Changes in the heart are observed mostly in "septic", subacute rheumatoid arthritis and in Still's disease. Cardiac lesions in rheumatoid arthritis are connected with microcirculatory disorders caused by immunopathological processes.
