Furthermore, using Pearson's correlation analysis, TCF21 CC genotypes showed positive correlations with stable angina (r = 0.130, p = 0.001) and STEMI (r = 0.203, p < 0.0001), while TCF21 GG genotypes exhibited a negative correlation with STEMI (r = -0.148, p = 0.003; Figure 1). This evidence concerns the gene TCF21 and angina pectoris.
