The polymorphisms of ApoE and paraoxonase (PON1) L55M (Met < Leu) allele genes lead to disorders in lipid metabolism and are related to atherosclerosis.
We related the PON1 M55L genotypes to the extent of atherosclerosis in left anterior descending coronary artery (LAD) in alcohol abstainers (0-1 g of alcohol/day), moderate consumers (1-36 g of alcohol/day) and drinkers (> 36 g of alcohol/day).
In logistic regression analysis, age (P<0.001) and the PON M/L55 genotype (P=0.015) were associated significantly with the severity of atherosclerosis in the common iliac arteries independent of smoking status, R/Q192 genotype, hypertension, diabetes mellitus, BMI and sex.
