When we analyzed these parameters in CAD-related HF patients stratified according to combined GSTA1/GSTP1 (rs1695) genotypes (Table 7), only carriers of variant GSTA1∗B/GSTP1∗Val (rs1695) alleles had significantly decreased LVESD compared to individuals with GSTA1∗AA/GSTP1∗IleIle (p = 0.021). Here, GSTP1 is linked to coronary artery disorder.
