The CHD patients had higher levels of apoB (P = 0.022), TG/HDL-C (P = 0.036), TC/HDL-C (P = 0.001) and apoB/apoAI (P = 0.002), and lower levels of HDL-C (P = 0.010) and apoAI (P = 0.002) than the CHD-free subjects in men; the CHD patients had higher levels of TG (P = 0.016), LDL-C (P = 0.017), apoB (P = 0.020), TG/HDL-C (P = 0.015), TC/HDL-C (P = 0.001), LDL-C/HDL-C (P < 0.001) and apoB/apoAI (P = 0.004) than the CHD-free subjects in women. This evidence concerns the gene APOB and coronary artery disorder.
