METHOD FOR PREDICTION OF ADDITIONAL RISK OF THROMBOEMBOLIC COMPLICATIONS IN SENILE PATIENTS WITH ATRIAL FIBRILLATION Russian patent published in 2020 - IPC A61B5/00 G16H50/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, cardiology, gerontology. Age is determined in the patients, collect data of anamnesis on the presence of atrial fibrillation (AF), arterial hypertension, diabetes mellitus, ischemic heart disease – acute myocardial infarction, peripheral arterial atherosclerosis, congestive chronic cardiac failure (CCF), thromboembolic complications (TEC), including cerebral strokes. Diagnosing the presence of AF by analyzing the recorded electrocardiogram (ECG) or the Holter ECG monitoring results, the presence of atherosclerotic plaques by duplex scanning of the arteries; reduction of ejection fraction (EF) in patients with CCF symptoms accompanying echocardiography. Prescription/non-prescription of oral anticoagulants (OAC) is assessed. Using the questionnaire, the patient's adherence to the recommended OAC intake is determined. According to the declared mathematical formula additional risk index of TEC (TEC ARI) is calculated. Value ARI TEC shows the low risk – if the value is up to 0.2, the average risk is 0.3–0.6, the high risk is 0.7–0.9 and the ARI TEC is more than 1.0 – a very high additional risk of TEC.

EFFECT: method provides a universal and accurate assessment of the additional risk of TEC in elderly patients suffering AF, by determining the total risk of TEC, evaluating the conducted anticoagulant therapy, as well as diagnosing adherence of the patients to the recommended treatment.
