Comparative estimation of secondary infectious endocarditis course with atrioseptal defect among inhabitants of the Far North and middle zone of Russia

Abstract

Aim. Comparative estimation of infectious endocarditis (IE), complicating secondary artioseptial defect course (SADC) among people living in the Far North and the middle zone of Russia.

Methods and materials. The retrospective analysis of medical histories was conducted in 2 groups of patients with a congenital valvular disease complicated with IE. There were used general clinical methods, electrocardiographic diagnostics, Xray study of the lungs, bacterial research of an operational material (inoculation from a pericardium and defect).

Results. The greatest frequency IE complicating SADC is observed in both groups of patients with duration of disease more than 21 years. Insufюciency of blood circulation (BC) in group of patients from Yakutia was detected authentically more often. A microthromboemolic syndrome was more often marked in group of sick northerners. Frequency of chronic tonsillitis among patients from Yakutia authentically exceeded a corresponding parameter among inhabitants of Western Siberia. After inoculation from a pericardium and edges of atrioseptial defect staphylococcus were sowed more often.

Conclusion. Secondary IE, complicating SADC, among people living in the Far North has severer clinical symptomatology on a background of the multiple nidus of chronic infections, than in group of inhabitants of the middle zone of Russia. In conditionalpathogenic microЯora sick northerners have prevailing staphilococcus.
