METHOD FOR PREDICTION OF THROMBOEMBOLIC COMPLICATIONS IN PATIENTS WITH HIGH-RISK ARRHYTHMIAS Russian patent published in 2021 - IPC A61B5/00 G01N33/48 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to cardiology, and is intended to predict the possibility of developing thromboembolic complications in various types of extrasystolic arrhythmia and atrial fibrillation. The risk of thromboembolic complications in high-risk arrhythmias is determined as follows: 1 point is assigned for the presence of each of the following signs: heart failure of II functional class and higher according to NYHA; arterial hypertension; diabetes mellitus; the presence of heterogeneous atheroma of any localization; extrasystoles after the peak of transmitral blood flow in the phase of rapid filling; the patient's age up to 65 years; 2 points are assigned in the presence of: stroke, transient ischemic attacks or systemic thromboembolism in history; hemodynamically significant stenosis of carotid bifurcation; extrasystoles in the phase of isovolumic decrease in intraventricular pressure before the mitral valve opens; extrasystoles to the peak of transmitral blood flow in the phase of rapid filling; group extrasystole, paroxysms of ventricular tachycardia; the patient is over 65 years old. Additionally, atrial fibrillation is assessed depending on the duration of pauses between ventricular contractions: atrial fibrillation with a pause between ventricular contractions of less than 1 second is estimated at 1 point; atrial fibrillation with a pause between ventricular contractions of more than 1 second, but less than 2 seconds at 2 points; atrial fibrillation with a pause between ventricular contractions of 2 seconds or more at 3 points. The points are summed up, assessing the risk of thromboembolic complications as very high with a total of 15 to 17 points, high with a total of 11 to 14, medium with a total of 7 to 10, low with a total of 3 to 6, very low with total points from 1 to 2.

EFFECT: allows predicting thromboembolic complications in patients with high-risk arrhythmias due to additional assessment of atrial fibrillation, depending on the duration of pauses between ventricular contractions.
