Popis:	Aim. To study laboratory and magnetic resonance imaging (MRI) characteristics of infarction area depending on left ventricular (LV) global systolic function in patients with acute myocardial infarction (AMI) after revascularization.Material and methods. A total of 78 patients with primary AMI were included. On days 7-10, contrast-enhanced cardiac MRI was performed. Blood brain natriuretic peptide (BNP) was analyzed. Cardiac MRI was used to determine the characteristics of scar tissue, peri-infarct zone (PIZ), microvascular obstruction (MVO), intramyocardial hemorrhage (IMH) and the global contrast index.Results. According to the MRI, patients were divided into following groups: group 1 — LV ejection fraction (LVEF) ≥50% (n=50), group 2 — LVEF 40-49% (n=21), group 3 — LVEF
