[Fractalkine level in chronic heart failure of varying severity]

Purpose of research. To examine the level changes of fractalkine in patients with chronic heart failure (CHF) depending on the ejection fraction of the left ventricle and the stage of the disease.

In total 340 people were examined. Of these, 280 patients with CHF divided into groups depending on the ejection fraction of the left ventricle (with a preserved and reduced ejection fraction) and the stage of the disease (stage I to III). Fractalkine level was determined by method of enzyme immunoassay in blood plasma.

We revealed an increase in the level of fractalkine in patients with CHF with preserved and reduced ejection fraction compared with the control group. An increase in the level of fractalkine was more pronounced in patients with reduced ejection fraction. In the group of patients with preserved ejection fraction of stage IIB+III, a statistically significant decrease in the level of fractalkin was observed in comparison with patients with stage I to stage III. The method of correlation analysis established that there is a correlation between the level of fractalkine and clinical manifestations of CHF.

It was revealed an increase in the level of fractalkine in blood plasma in patients with CHF with the control group, which was more pronounced in patients with reduced ejection fraction and the presence of correlation level fractalkine with indicators of clinical manifestations of CHF.
