THE SIGNIFICANCE OF HIGH-SENSITIVE TROPONIN I UNDER VARIOUS FORMS OF INFECTIOUS ENDOCARDITIS

The study was carried out to analyze dynamics of highly sensitive Troponin I in patients with infectious endocarditis with the purpose of specifying its role in evaluation of myocardium condition and prognosis of disease. The sampling included 241 patients being on treatment in the S.P. Botkin municipal clinical hospital. The article presents characteristics of disease at actual stage, clinical laboratory and instrumental comparisons permitted to establish features and patterns of alterations of hsTnI in patients with primary and secondary infectious endocarditis. The relationship is established between increasing of indicator and clinical expression of infectious toxic syndrome, presence of complications, multi-functional alterations of myocardium and functional class of cardiac insufficiency. It is demonstrated that absence of positive dynamics of marker against the background of therapy is a unfavorable prognostic indication and increases a risk of lethal outcome.The obtained results testify undeniable involvement of cardiac muscle into development of pathological process under infectious endocarditis that alongside with valvular pathology determines severity of cardiac insufficiency and prognosis of disease.
