As shown in Fig. 1; Table 1 circulating GIP levels were significantly lower in patients with STEMI compared to clinically stable patients without myocardial infarction (216.82 pg/mL [Q1–Q3: 52.37–443.07] vs. 271.54 pg/mL [Q1–Q3: 70.12–542.41], p = 0.0266). This evidence concerns the gene GIP and myocardial infarction.
