We investigated the association between histologically defined atherosclerotic lesions in the carotid arteries and the genetic variants of APOE and LPL in a population-based sample of Finns aged 85 or over. Post-mortem analysis of carotid arteries was performed in 240 subjects. Atherosclerotic lesions were categorized according to the modified American Heart Association criteria, and classified into four different categories: pathological intimal thickening (PIT), fibrous cap atheromas (FCA), calcified lesions (CL), and atherosclerotic burden (AB) (a combination of the other three categories). APOE epsilon 4 genetic variant was associated with PIT (p = 0.018) and AB (p = 0.006) in the carotid arteries, and its effect was independent of the serum lipid levels. The genetic variant LPL Ser447Ter was protective against FCA (p = 0.031) and AB (p = 0.012), while APOE epsilon 2 was protective against FCA (p = 0.035). Our results suggest that the APOE epsilon 4, epsilon 2 and LPL Ser447Ter variants may have different roles in the atherosclerotic process and their effects are seen even in the oldest old population.
