FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to cardiology, and can be used to determine a risk of developing atrial fibrillation in patients with ischemic heart disease, taking omega-3 polyunsaturated fatty acids in coronary bypass. Following parameters are determined: age in years, left atrial diameter in millimeters, concentration of reduced glutathione in mcmol/g of blood plasma erythrocytes hemoglobin after operation, concentration of malonic dialdehyde in mcmol/g of blood plasma erythrocytes hemoglobin after operation, activity of matrix metalloproteinase-9/mg of blood plasma after operation, omega-3 index in blood plasma erythrocytes membrane after operation. Risk index of the atrial fibrillation P is calculated by an original calculation formula. If P is less than 0.5, developing atrial fibrillation is not predicted; if the P index is greater than or equal to 0.5, the patient is predicted to develop atrial fibrillation.
EFFECT: method enables determining a risk of developing atrial fibrillation in patients with ischemic heart disease, taking omega-3 polyunsaturated fatty acids in coronary artery bypass grafting.
