When LVEF is added to this system, non-inferior MI has 0 points, and LVEF has 10 points if ≤15%, 7 points if 16–25%, 5 points if 26–35%, 2 points if 36–45%, and 0 points if >45%.

on support measures, including vasopressors, inotropes±IABP. Obtained prior to or without IABP support in 76%.
‡
When dichotomized to assess elderly risk, patients ≥75 years assigned 9 points and patients <75 years assigned zero points.
