We reviewed the autopsy material of 169 patients with rheumatoid arthritis (RA) and studied the cardiac changes is these patients. Systemic vasculitis was observed in 26 cases (15.38%) among 169 patients with RA. In 17 cases (10%) we found vasculitis of the subepicardial and/or intramural coronary vessels. Coronary arteritis or arteriolotis has led to multifocal small, and/or large myocardial infarctions in 10 cases (5.9%) and was the cause of progressive cardiac insufficiency, the direct cause of death. Multifocal circumscribed myocardial infarction reported in rheumatoid disease. In 8 cases rheumatoid nodules were found in the myocardium, 3 of them related to vasculitis. We suggest that rheumatoid nodules are the most severe form of necrotizing granulomatous vasculitis. Pathognomic nodular rheumatoid pericarditis was seen in 3 cases and diffuse rheumatoid pericarditis in another case. Pathognomic nodular valvulitis was found in 7 cases. Rheumatoid nodules localized to the epi-, myo-, or endocardium were observed on 9 patients. Generalized secondary amyloidosis was observed in 32 (18.93%) of the 169 patients with RA. Secondary amyloidosis was prevalent in the heart in 29 of 32 cases (relative frequency: 90.62%).
