Introduction. Acute myocardial infarction (AMI) is one of the leading causes of death worldwide, and its combination with atrial fibrillation (AF) significantly aggravates the course of the disease and increases the risk of thromboembolic complications. The relationship between AF and coronary artery disease remains an important problem in modern cardiology, as AF can be both a consequence and a cause of coronary blood flow deterioration.
Materials and Methods. The study was conducted at the Republican Specialized Scientific and Practical Medical Center of Cardiology, involving 236 patients with AMI of various localizations, of which 98 had AF. Results. Analysis of angiographic data revealed that: In patients with anterior AMI and AF, damage to the left anterior descending artery (LAD) and its diagonal branches is more common. The involvement of the right coronary artery (RCA) and the circumflex artery (CX) is characteristic of inferior AMI. Patients with persistent AF have more pronounced multifocal coronary artery lesions compared to those with paroxysmal AF. A high frequency of chronic occlusions and thrombotic complications has been identified in patients with AMI and AF, which requires early and aggressive revascularization tactics.
Conclusion. In patients with AMI and AF, a high frequency of multifocal lesions of the coronary arteries is noted, which requires an individualized approach to managing such patients. Angiographic assessment of coronary artery condition is an important tool for choosing optimal treatment tactics and preventing complications. Timely revascularization in combination with adequate anticoagulant therapy plays a key role in improving the prognosis of patients with combined pathology.
