STRUCTURAL AND FUNCTIONAL PARAMETERS OF THE CARDIOVASCULAR SYSTEM IN PATIENTS WITH ATRIAL FIBRILATION AFTER A STROKE
Atrial fibrillation (AF) is an important medical problem due to its high prevalence and increased mortality. With the development of a stroke, the patient has a fatal situation not only for the brain, but also for the whole organism, which leads to a deterioration in the general somatic status. In this article, we analyze the structural and functional parameters of the cardiovascular system during AF in patients who have had a stroke, in order to identify the dynamics of indicators in patients after a stroke. The aim of the study was to evaluate the structural and functional parameters of the cardiovascular system in patients with stroke after atrial fibrillation. In the main group, we selected 28 patients with non-valve atrial fibrillation, who had previously suffered an ischemic stroke. The comparison group (30 people) included patients with non-valve AF without stroke and transient ischemic attacks in history, comparable in age and gender. All patients underwent laboratory diagnostics by electrocardiographic and echocardiography, ultrasound duplex scanning of the arteries of the brachiocephalic zone, and also filled out an individual questionnaire. As a result of the study, we revealed statistically significant differences between the groups with respect to echocardiographic parameters (thickness of the interventricular septum, thickness of the posterior wall of the left ventricle (LV) and myocardial mass index) in patients after ischemic stroke. An increase in the risk of stroke with an increase in the thickness of intima media complex > 0.9 mm is shown. The left atrial volume index is higher than normal in both groups, which indicates the presence of LV diastolic dysfunction.
