PFKFB2 and myocardial infarction: To further explore the expression characteristics of PFKFB2, we also studied on its expression level in patients with UA and no previous history of MI, we found that the expression of PFKFB2 in UA was similar to that in AMI, with no significant difference, but higher than that in OMI (Supplementary Figures 3A,B and Supplementary Tables 3, 4).
