METHOD FOR PREDICTING A COMPLICATED COURSE OF THE POSTOPERATIVE PERIOD IN PATIENTS WITH ISCHEMIC HEART DISEASE WITH A REDUCED CONTRACTIVE HEART FUNCTION AFTER OPEN HEART OPERATION

摘要

The invention relates to medicine, namely to cardiac surgery, laboratory diagnostics. In accordance with the invention, a method for predicting a complicated course of the postoperative period in patients with coronary heart disease with reduced contractile heart function after open heart surgery is described, which consists in the fact that the patient undergoes an echocardiographic study in the preoperative period, in which they confirm the presence of a reduced contractility of the heart and determine the severity of functional ischemic mitral insufficiency, then assess the level in cr the ovaries of the sST2 myocardial fibrosis biomarker, compare it with a reference threshold value and at a sST2 level of less than 45 ng / ml establish a low risk of complicated postoperative course, and at an sST2 level of more than 45 ng / ml, a high risk of developing low cardiac output syndrome in postoperative period after open heart surgery. The technical result achieved by the invention is to improve the accuracy, reliability and quality of the prognosis of the complicated course of the postoperative period in patients with coronary heart disease with reduced contractile heart function after open heart surgery.
