The results of percutaneous intervention in acute coronary syndrome depending on the type of mechanical hemodynamic support of blood circulation

Aim. To compare the results of high-risk percutaneous coronary intervention (PCI) in patients with acute non-ST elevation myocardial infarction and multivessels lesion of the coronary arteries (CA) with the support of extracorporeal membrane oxygenation (ECMO) and intra-aortic balloon counterpulsation (IABC). Methods. 34 patients aged 68.2 ± 10.6 were included in the study. 18 patients underwent PCI + ECMO (PCI + ECMO group) and 16 patients underwent PCI + IABC (PCI + IABC group). The major adverse cardiovascular events (MACE) in the follow-up included death, myocardial infarction, stroke, repeated non-elective myocardial revascularization. Results: At the 12-months follow-up, the combined endpoint of MACE was 22.4% (n = 4) in the PCI + ECMO group vs. 68.7% (n = 11) in the PCI + IABC group (p = 0.002).
