TL;DR: A DASI score of 34 represents a threshold for identifying patients at risk for myocardial injury, myocardia infarction, moderate-to-severe complications, and new disability, and a nested cohort analysis of the Measurement of Exercise Tolerance before Surgery study characterised the association of preoperative DASi scores with postoperative death or complications.

TL;DR: Both anaemia and poor functional capacity are associated with postoperative complications and may therefore be modifiable targets for preoperative optimisation.
