[A dynamic study of plasma fibronectin in patients undergoing heart operations under extracorporeal circulation].

In a preliminary analysis the level of plasma fibronective as well as the total protein and albumin were followed dup in cardiac patients. The dynamic changes of values of the parameters perioperatively and up to the 96-th postoperative hour were taken into consideration. The authors make the conclusion that the fibronectine reduction is not specific and reflects not so much the destruction of the heart muscle but the reparation processes following the surgical trauma.
