True left ventricular aneurysm in acute myocardial infarction: immediate and long-term outcomes, prognostic factors, and treatment

An important place in the structure of cardiovascular morbidity is occupied by myocardial infarction (MI), especially complicated MI, including complicated by the formation of left ventricular (LV) aneurysm. The latter is a very formidable complication and leads to such life-threatening conditions as ventricular arrhythmias, heart failure, thromboembolism. The purpose of the review is to analyze the publications of foreign and Russian authors on risk factors, outcomes and treatment of patients with postinfarction LV aneurysm. Attention is paid to the role of registers in the study of this problem, as well as the analysis of literature data on the prevalence of such a complication as MI during the COVID-19 pandemic (COrona VIrus Disease 2019). It is shown that the registers of acute coronary syndrome, as a rule, do not contain separate data on patients with a formed LV aneurysm, risk factors for its development and outcomes in this group of patients. Postinfarction LV aneurysm can form only after transmural MI; therefore, it is important to keep records of patients diagnosed with transmural MI, primarily in the form of a register.
