PREVENTION OF THROMBOTIC COMPLICATIONS IN PATIENTS WITH REDUCED LEFT VENTRICULAR EJECTION FRACTION UNDER THE CONTROL OF LOW-FREQUENCY VISCOMETRY
Keywords:
left ventricular ejection fraction, thrombotic complications, cardiac surgeryAbstract
In patients with reduced left ventricular ejection fraction who underwent cardiac surgery, risk of perioperative thrombotic complications is elevated. The emergence of these complications in patients with reduced left ventricular ejection fraction (LVEF) significantly impairs the survival in early and late postoperative periods. In order to determine the adequacy of thromboprophylaxis, an observational study of the hemostasis system was performed using low-frequency viscometry in 42 patients of the study group in the early postoperative period. The obtained results indicate that the prevention of thrombotic complications carried out with continuous intravenous infusion of small doses of unfractionated heparin is adequate. Further research is needed to improve the methods of preventing the thrombotic complications.
