Role of the APOE polymorphism in carotid and lower limb revascularization: A prospective study from Southern Italy.
PloS One 2017
BACKGROUND: Atherosclerosis is a complex multifactorial disease and the apolipoprotein E (APOE) polymorphism has been associated to vascular complications of atherosclerosis.
OBJECTIVES: To investigate the relationship between the APOE genotypes and advanced peripheral vascular disease.
MATERIALS AND METHODS: 258 consecutive patients (201 males and 57 females, mean age 70.83 ± 7.89 years) with severe PVD were enrolled in a 42-months longitudinal study (mean 31.65 ± 21.11 months) for major adverse cardiovascular events. At follow-up genotypes of the APOE polymorphism were investigated in blinded fashion.
RESULTS: As compared with ε3/ε3, in ε4-carriers a significant higher incidence of major adverse cardiovascular events (35.58% vs. 20.79%; p = 0.025) and total peripheral revascularization (22.64% vs. 5.06%; p < 0.001) was observed. Prospective analysis, showed that ε4-carriers have an increased hazard ratio for major adverse cardiovascular events (adjusted HR 1.829, 95% CI 1.017-3.287; p = 0.044) and total peripheral revascularization (adjusted HR = 5.916, 95% CI 2.405-14.554, p <0.001).
CONCLUSIONS: The ε4 allele seems to be risk factor for major adverse cardiovascular events, and in particular for total peripheral revascularization in patients with advanced atherosclerotic vascular disease.
