Predicting Ejection Fraction after Myocardial Infarction

FULL TEXT
IN RESPONSE:
We appreciate the opportunity to respond to the comments of Dr. Darbar and colleagues and Dr. Zema on our clinical rule to identify patients with preserved LVEF after myocardial infarction.
Darbar and colleagues applied our clinical prediction rule to a subset of patients admitted to their coronary care unit. They had data on 55 of 75 randomly selected patients; only 13 of these patients were predicted to have an LVEF of 40% or greater. Measurements showed that only 9 of these 13 patients had preserved LVEF, yielding a positive predictive value of 69%; this is apparently much lower than the 98% positive predictive value yielded in our patient population. On the basis of their results, Darbar and colleagues question the generalizability of our prediction rule to patients after myocardial infarction. They suggest that their patients were unselected and heterogeneous and that our patients were, in part, selectively screened.
