Characteristic of infectious status in patients with acutely decompencated chronic heart failure and its impact on annual prognosis

Abstract

Aim. The assessment of infectious status in patients with acutely decompensated chronic heart faiure (ADCHF) without evident signs of acute inflammatory stress and its impact on the 1 year prognosis. Materialandmethods. Totally, 65 patients with ADCHF of ischemic origin investigated, age 67,3±2,3 y.o. All patients were taken markers of phagocytosis and inflammatory stress as well as antibodies to Streptococcus, Cytomegalovirus (CMV), Epstein-Barr virus (VEB), Candida albicans, Toxoplasma gondii, Aspergillus, Mycoplasma hominis and pneumonia and also level of lipopolysaccharids (LPS) of gram-negative bacteriae. Results. More often LPS of gram-negative bacteriae were revealed in patients with ADCHF and further in decreasing order - antibodies to CMV, VEB, Streptococcus, Candida, Aspergillus and LPS. All patients have been infected by at least 2 pathogens, more than 90% of them had 3 ones or more. Mortality in first 12 months observation correlated with quantity of patient's pathogenic patterns (r=0,52, p=0,004). Dependency of one-year mortality from degree of viral-bacterial mixt contamination was almost linear. CMV was a monopathogen with strongest correlation with mortality (r=0,39, p=0,001). In patients with more significant infection bigger rate of re-hospitalizations about new ADCHF correlated with number of pathogens was observed (r=0,61, p=0,001). Conclusion. Chronic latent infection with a significant number of pathogens is characteristic of patients with low-ejection ADCHF of ischemic genesis with a significant number of pathogens: more than 90% of patients had three or more. The most common exogenous pathogens in the study sample of patients with chronic obstruc- tive heart failure were CMV, EBV, and hemolytic streptococcus, of the potentially endogenous ones, gram-negative intestinal bacteria. The number of infectious agents in patients with chronic obstructive heart failure has a direct correlation with deaths and re-admission to hospital with total heart failure within 1 year after discharge from the hospital.
