Besides, we found that PFN2 was negative associated with creatinine kinase-myocardial band (CK-MB) (Pearson correlation = −0.321, p = 0.012) and diastolic blood pressure (DBP) (Pearson correlation = −0.300, p = 0.020) (Supplementary Figure 1), which both indicated poor prognosis of MI (30, 31). This evidence concerns the gene PFN2 and myocardial infarction.
