[Cardiac lesion in the Churg-Strauss syndrome].

The Churg-Strauss syndrome is a systemic vasculitis, the manifestations of which are asthma, eosinophilia, pulmonary infiltrates, poly- and mononeuropathy, polyserositis. Along with nodular polyarteritis and nonspecific aortoarteritis, the Churg-Strauss syndrome belongs to a group of systemic vasculitis, in the clinical picture of which cardiac lesion is recognized as one of the leading visceral manifestations and may be a common cause of fatal outcomes. In the Churg-Strauss syndrome, cardiac pathology may be associated with the involvement of the endocardium, myocardium, and pericardium. The paper describes a case showing the poor course of the disease in a young female patient in whom the heart is involved in a pathological process with the development of severe heart failure, resulting in death. There is a rare concomitance of diffuse myocardial damage, coronary lesion, and valvular pathology - eosinophilic endocarditis. The diagnosis has been verified on the basis of the data of clinical and additional studies and the results of microscopic studies. The data available in the Russian and foreign literature on cardiac pathology in patients with the Churg-Strauss syndrome are analyzed.
