Atrial fibrillation (AF) is the most widespread rhythm disturbance among the population of all countries of the world. Moreover, in recent years, there has been a further increase in the prevalence of AF. The adverse effect of AF on life prognosis in patients of this profile is primarily due to a significant increase in the incidence of cardioembolic stroke and systemic thromboembolic complications.
The clinical significance of atrial fibrillation (AF) is associated with a five-fold increase in the risk of stroke and a 1.5-2-fold increase in mortality in the population of patients suffering from this type of arrhythmia. Therefore, there is no doubt that the use of effective strategies for the prevention of cardiovascular complications and the development of chronic heart failure is the most important component in the management of a patient with AF. The prognosis in patients with AF with the development of heart failure (HF) significantly increases the risk of lethal cardiothromboembolism (CTHE), therefore, the diagnosis of CHF in early functional classes allows for timely enhancement of preventive antithrombotic therapy in accordance with the increased risk of CTHE.
The study of the prevalence of AF among patients with coronary artery disease in the center, taking into account the clinical manifestations and characteristics of AF episodes in order to predict complications and CHF remains an urgent problem.
