ECHOCARDIOGRAPHIC PARAMETERS OF MYOCARDIAL REMODELING IN PATIENTS WITH ATRIAL FIBRILLATION IN COMBINATION WITH ARTERIAL HYPERTENSION
Introduction: Atrial fibrillation (AF) is the most common, sustained supraventricular arrhythmia. The prevalence of this heart rhythm disturbance is 1-2% in the general population. AF is combined with many cardiovascular diseases, but most often with arterial hypertension. As a result of the irregular contraction of certain muscle atrial fibers, the mechanical systole of the atria and the irregular contraction of the ventricular myocardium are lost, the process of changing the electrophysiological and structural properties starts, which leads to changes in the geometry of the heart and intracardiac hemodynamics, as a result of which myocardial remodeling, impaired systolic and diastolic function of the heart develops.
