May flag impaired LVEF pre-CABG; observational data leaves open prospective validation for risk stratification.
Do clinical and exercise test findings predict depressed LVEF in patients undergoing CABG?
Clinical data, such as history of myocardial infarction and pathological Q-waves, are better predictors of depressed LVEF than exercise test findings in patients undergoing CABG.
Herlitz et al. (2008) studied this question.
