Abstract：Objective o retrospectively study the outcome of extracorporeal membrane oxygenation (ECMO) in elderly pa?tients with refractory postoperative cardiogenic shock ( PCS) after coronary artery bypass grafting ( CABG) from our center, and to ana?lyze the possible risk factors. Methods A total of 119 consecutive patients treated with ECMO because of PCS after CABG or unsuc?cess fully weaning from cardiopulmonary bypass ( CPB) during surgery from January 2011 to December 2014 were reviewed. Logistic a?nalysis was performed to identify the risk factors of the clinical outcome. Results There were 42 elderly patients (>=65years) with a mean age of 69.4±3.5 years. Twenty cases (47.6%) success fully weaned from ECMO and ten cases (23.8%) were discharged from hospital. There were 77 non-elderly patients (<65 years) with a mean age of 55.1±6.6 years. Forty-one (53.2%) cases success fully weaned from ECMO and 33 (42.9%) cases were discharged from hospital. Between the elderly and non-elderly patients, significant difference was noted in lower limb ischemia (21.4% vs 6.5%), renal failure (42.9% vs 16.9%) and the frequency of dialysis (31.0%vs 13.0%) . Logistic analysis found that renal failure and lower limb ischemia wereindependent risk factors associated with theclinical outcome of patients. Conclusions ECMO is an effective treatment for eldely patients with PCS after CABG; Renal failure and lower limb ischemia are indepedent risk factors of the outcome of ECMO support.
