The plasma level of adrenomedullin in the anterior MI group (0.42 ± 0.15 ng/ml) was significantly higher than that in the group with no previous MI (0.30 ± 0.07 ng/ml) and the posterior/inferior MI group (0.33 ± 0.05 ng/ml) (p = 0.002 and p = 0.043, respectively) (Fig. 1A). This evidence concerns the gene ADM and myocardial infarction.
