[Analysis of results of surgical treatment of patients with infectious endocarditis].

The results of surgical treatment of 180 patients were studied according to the character of infectious endocarditis (primary--PIE and secondary--SIE), the functional class (FC) in the preoperative period, and the patients' immune status. The survival of patients with PIE (with hospital mortality taken into account) was somewhat higher than that of patients with SIE. Survival in the late-term periods was significantly higher in patients with PIE. There were no fatal outcomes among patients with PIE of FC III, mortality among patients with SIE was 7.7%; mortality in FC IV was, respectively, 10 and 21.6%; the mortality rate among patients with PIE and SIE of FC V was 43.5 and 57.5%, respectively. The late-term results were good in 85.5 and satisfactory in 14.5% of patients. Twenty-one (16%) patients died. Cardiac failure and recurrent sepsis were the main causes of fatal outcomes. The preoperative immunological parameters (the concentration of ceruloplasmin, blood serum IgG and IgM, the activity of lymphocyte mitochondrial enzymes and the neutrophil test) reflect the activity of infectious endocarditis and have an effect on the development of postoperative complications and on the mortality.
