Objectives: The quality of life after extracorporeal membrane oxygenation therapy has emerged as an important issue for extracorporeal membrane oxygenation survival; however, its association with long-term prognosis has not been identified. We investigated the changes in the quality of life after extracorporeal membrane oxygenation among the survivors and examine the association between a worse quality of life and 3-year all-cause mortality.Design: This was a population-based cohort study.Setting: Data were obtained from the National Health Insurance Service database in South Korea.Patients: Adult individuals (≥ 18 yr old) who received extracorporeal membrane oxygenation therapy from 2006 to 2017 were included. Extracorporeal membrane oxygenation survivors were defined as patients who had survived for 1-year after the initiation of extracorporeal membrane oxygenation therapy.Interventions: None.Measurements and Main Results: The income level, employment status, and registered disability were examined before and 1-year after extracorporeal membrane oxygenation therapy. The decreased income level, job loss, and newly acquired disability were considered as change in the quality of life among extracorporeal membrane oxygenation survivors. A total of 5,821 adult extracorporeal membrane oxygenation survivors were included in the final analysis, and 2,959 patients (50.8%) experienced quality of life change. Specifically, 1,782 patients (30.6%) experienced a decrease in income, 682 (11.7%) lost their jobs, and 1,540 (26.5%) had a new disability within 1-year after extracorporeal membrane oxygenation therapy. In the multivariable Cox regression model, newly acquired disability was associated with 2.31-fold higher 3-year all-cause mortality among extracorporeal membrane oxygenation survivors (hazard ratio, 2.31; 95% CI, 1.79-2.97; p < 0.001), while job loss (p = 0.180) and decreased income (p = 0.993) were not associated with the 3-year all-cause mortality.Conclusions: At 12 months after extracorporeal membrane oxygenation therapy, nearly half survivors experienced quality of life worsening such as unemployment, decreased income, and new disability. Additionally, among the three factors, acquiring a new disability might significantly increase the 3-year mortality. This is the first study to report the association between changes in the quality of life and long-term prognosis in extracorporeal membrane oxygenation survivors. [ABSTRACT FROM AUTHOR]

Objectives: To identify whether the prognostic implications of Vasoactive Inotropic Score according to use of mechanical circulatory support differ in the treatment of acute myocardial infarction complicated by cardiogenic shock.Design: A multicenter retrospective and prospective observational cohort study.Setting/patient: The REtrospective and prospective observational Study to investigate Clinical oUtcomes and Efficacy registry includes 1,247 patients with cardiogenic shock from 12 centers in Korea. A total of 836 patients with acute myocardial infarction complicated by cardiogenic shock were finally selected, and the study population was stratified by quartiles of Vasoactive Inotropic Score (< 10, 10-30, 30-90, and > 90) for the present study.Interventions: None.Measurements and Main Results: Primary endpoint was in-hospital mortality and secondary endpoint was follow-up mortality. Among the study population, 326 patients (39.0%) received medical treatment alone, 218 (26.1%) received intra-aortic balloon pump, and 292 (34.9%) received extracorporeal membrane oxygenation. In-hospital mortality occurred in 305 patients (36.5%) and was significantly higher in patients with higher Vasoactive Inotropic Score (15.6%, 20.8%, 40.2%, and 67.3%, for < 10, 10-30, 30-90, and > 90; p < 0.001). Vasoactive Inotropic Score showed better ability to predict in-hospital mortality in acute myocardial infarction patients with cardiogenic shock who received medical treatment alone (area under the curve: 0.797; 95% CI, 0.728-0.865) than in those who received intra-aortic balloon pump (area under the curve, 0.704; 95% CI, 0.625-0.783) or extracorporeal membrane oxygenation (area under the curve, 0.644; 95% CI, 0.580-0.709). The best cutoff value of Vasoactive Inotropic Score for the prediction of in-hospital mortality also differed according to the use of mechanical circulatory support (16.5, 40.1, and 84.0 for medical treatment alone, intra-aortic balloon pump, and extracorporeal membrane oxygenation, respectively). There was a significant interaction between Vasoactive Inotropic Score as a continuous value and the use of mechanical circulatory support including intra-aortic balloon pump (interaction-p = 0.006) and extracorporeal membrane oxygenation (interaction-p < 0.001) for all-cause mortality during follow-up.Conclusions: High Vasoactive Inotropic Score was associated with significantly higher in-hospital and follow-up mortality in patients with acute myocardial infarction complicated by cardiogenic shock. The predictive value of Vasoactive Inotropic Score for mortality was significantly higher in acute myocardial infarction patients with cardiogenic shock treated by medical treatment alone than in those treated by mechanical circulatory support such as intra-aortic balloon pump or extracorporeal membrane oxygenation.

The article discusses a retrospective, single-center observational study on the survival of patients with inhospital cardiac arrest who received extracorporeal cardiopulmonary resuscitation (E-CPR) and those who underwent the conventional CPR. A total of 406 adult patients were involved in the study at Samsung Medical Center in Seoul, South Korea. It found that E-CPR had more survival benefits than conventional CPR.
