The level of IL-6 in the pericardial fluid in the anterior MI group (193.51 ± 62.29 pg/ml) was significantly higher than that in both the group with no previous MI (105.25 ± 69.71 pg/ml) and the posterior/inferior MI group (139.91 ± 54.18 pg/ml) (p = 0.000and p = 0.033, respectively) (Fig. 2B). This evidence concerns the gene IL6 and myocardial infarction.
