[The cerebral sodium uretric peptide (see text symbol) patients with chronic cardiac insufficiency under decreased and preserved ejection fraction].

The concentration of cerebral sodium uretic peptide was analyzed in patients with chronic cardiac insufficiency and in healthy volunteers. The study established that concentration of cerebral sodium uretic peptide was higher in patients with chronic cardiac insufficiency as compared control group and reflected severity of pathologic process. In patients with decreased ejection fraction the levels cerebral sodium uretic peptide were higher as compared with patients with preserved ejection fraction. According data of the present study the existing threshold of concentration of cerebral sodium uretic peptide has a lower diagnostic sensitivity to exclude chronic cardiac insufficiency (100 pg).
