Aim:
To evaluate the effect of body composition on prediction of community-acquired pneumonia caused by Str. pneumoniae in patients with decompensated CHF.
Materials And Methods:
The study included 216 patients. The pneumonia agent was identified by sputum culture. Body composition with determining lean body mass and fat mass was evaluated using a bio-impedance analysis; body mass index (BMI) was calculated. Patients with BMI 18.5-24.9 kg/m2 were included into the study. Statistical analysis of obtained data was performed using the IBM SPSS Statistics 20 software.
Results:
The in-hospital mortality was 13.4 %; the one-year mortality was 29.6 %. Fat mass strongly, negatively correlated with a fatal outcome within a year, and the degree of lean body mass shortage moderately, positively correlated with the life span of patients.
Conclusion:
Body composition is significantly predictive for patients with decompensated CHF and community-acquired pneumonia caused by Str. pneumoniae.

According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
