Predicting Ejection Fraction after Myocardial Infarction

Michael J. Zema

FULL TEXT
TO THE EDITOR:
Silver and colleagues [1] describe an algorithm that uses factors derived from patient history and electrocardiographic data and that attempts to reliably identify patients with a resting LVEF of 40% or greater soon after myocardial infarction. This patient group is known to have a better prognosis, to require less initial drug therapy, and to need less specialized testing. Silver and colleagues' “prediction rule” consists of four sequential questions, all of which—if answered negatively—assure a global LVEF of 40% or greater with a predictive accuracy of 99%. Unfortunately, however, 47 of 116 patients (41%) in their “validation set” with an objectively proven LVEF of 40% or greater were not identified because of at least one positive answer to the four questions.
