To the Editor: Dr Najjar and colleagues1 reported that infarct size, assessed by cardiac magnetic resonance imaging (CMR) performed 2 to 6 days after study medication administration, did not differ between the erythropoietin and placebo groups. However, I am concerned whether infarct size is the optimal primary end point. It seems premature to replace traditional hard end points with infarct size as a surrogate end point to evaluate therapeutic efficacy of new drugs.
