Features of late coronary artery revascularization in patients with acute myocardial infarction

Objective. To compare the results of surgical and conservative treatment of patients with acute myocardial infarction admitted to a medical institution 48 hours after the occurrence of a coronary event.Materials and methods. The analysis of surgical treatment and postoperative observation of 43 patients with acute coronary syndrome admitted to hospital treatment within 72 to 120 hours from the onset of acute myocardial infarction was performed. All patients were divided into 2 groups: Group 1 (n = 17) included patients who underwent PCI for vital indications due to the presence of one or more emergency conditions in patients. Group 2 (n = 26) included patients who were hospitalized in a stable condition: they had no pain syndrome, life-threatening cardiac arrhythmias; hemodynamic parameters were within normal limits. The patients underwent complex conservative therapy, PCI was recommended on a delayed basis.Results. Two months after the treatment, higher myocardial functioning indices, and, as a result, better quality of life, were recorded in patients in the surgical treatment group. A greater number of fatal complications were recorded in patients after myocardial revascularization (which is explained, in all likelihood, by the extensive area and depth of damage to the heart muscle), and the number of non-fatal complications prevails in the conservative treatment group.
