The distributions of ALDH2 rs671 genotypes in patients with arteriosclerosis in single artery (χ2 = 0.492, P = 0.483) and patients with arteriosclerosis in multiple arteries (χ2 = 1.551, P = 0.213) were consistent with Hardy-Weinberg equilibrium, respectively. Here, ALDH2 is linked to arteriosclerosis.
