ABSTRACT
Extracorporeal membrane oxygenation (ECMO) has become an effective method in the treatment of adults and children with severe cardiac and pulmonary dysfunction that is resistant to conventional therapy. The aim of this article was to summarize an experience of ECMO usage for cardiac dysfunction, which develops in patients with coronary heart disease (CHD) during percutaneous transluminal coronary angioplasty. The study comprised a retrospective, single-center analysis of 23 patients with CHD (19 men and four women, average age 65.7 ± 12.3 years), who undertook the ECMO technique during percutaneous transluminal coronary angioplasty. A total of 13 (56.52%) patients died directly in the hospital, or 30 days after a discharge. Independent predictors of fatal outcomes were diabetes mellitus (odds ratio [OR] = 17.58; 95% confidence interval [CI] = 6.47-47.48; p = .00125), chronic renal failure (CRF) (OR = 20.81; 95% CI = 5.95-72.21; p = .00014), and damage to the right coronary artery (RCA) (OR = 25.51; 95% CI = 8.27-79.12; p = .00013). For deceased patients, the "no reflow" phenomenon was indicated in a larger percentage of cases (23.1% in the group of deceased, vs. 10% in the group of survivors). A routine connection to ECMO before the occurrence of cardiac events was significantly more often used in the group of survived patients (90% of cases) than in the deceased (p = .0000001). Diabetes mellitus, CRF, and damage to the RCA were independent predictors of mortality during percutaneous transluminal coronary angioplasty in patients with CHD. The routine use of ECMO in high-risk patients with percutaneous transluminal coronary angioplasty was a positive prognostic factor of patient survival.
