[Clinical and morphological aspects of infectious endocarditis]

Comparative analysis of anamnestic, clinical, laboratory and instrumental data involved 106 patients with infectious endocarditis treated in S.P. Botkin City Clinical Hospital in 2000-2011 and 92 ones admitted in 1985-1977. The results give evidence of ongoing pathomorphosis of infectious endocarditis as is apparent from the growing number of male patients, increased frequency of primary cases and previous invasive or intravascular manipulations, thromboembolic complications including pulmonary thromboembolism, right heart chamber endocarditis. Over half of the patients are socially unadapted C-peptide level is of diagnostic value for the assessment of inflammation activity, precursors of natriuretic peptide can be used to detect preclinical and clinical stages of cardiac failure related to infectious endocarditis. There is correlation between severity of inflammation and myocardial dysfunction. Early surgical intervention in the absence of effect of combined antibacterial therapy improves prognosis. Morphological studies of inflammation-related changes in myocardium, destruction of cardiomyocytes, dystrophic processes, and fibrosis play an important role in the development of cardiac insufficiency and prognosis of infectious endocarditis.
