In the August issue of this journal, Reffelmann and Kloner [1] reported the effects of sildenafil (Viagra) on myocardial infarct size following ischemia–reperfusion (I–R). These authors showed that pretreatment with 0.7 or 1.45 mg/kg of sildenafil prior to ischemia resulted in no protection against myocardial infarction. These findings are in contrast with a previous study from our laboratory [2] that demonstrated a significant reduction of infarct size in the rabbits
