Clinical Risk Factors of ECMO Support in Older Adults

A total of 99 patients (mean age: 76.4±6.4 years) were included. The most common condition requiring VA-ECMO support was cardiogenic shock. Among survivors on VA-ECMO, 28 (28.3%) patients were successfully weaned from support. Thirteen (13.1%) patients were successfully discharged. We found that cardiogenic shock (OR=3.158, P=0.013), acute physiology and chronic health evaluation II (APACHE II) score (OR=1.147, P<0.001), and simplified acute physiology score II (SAPS II) score (OR=1.054, P=0.001) were risk factors associated with survival on VA-ECMO.
