A recent report has suggested that the E4 allele of apolipoprotein (apo) E increases the risk of restenosis after percutaneous transluminal coronary angioplasty (PTCA) and also that it interacts synergistically with the deletion (D) allele of the angiotensin-converting enzyme (ACE) to increase the risk sixteen-fold. To investigate this further, we genotyped 231 subjects with successful PTCA who underwent planned repeat angiography at 4 months to assess the degree of restenosis. Subjects carrying the apo E4 allele (n = 71) were well matched with non-carriers (n = 160) for clinical and pre- and post-PTCA angiographic features. We found no increase in either apo E4 allele frequency (18.4% versus 15.6%, P = 0.42) or apo E4 homozygosity (2/106 versus 5/125, P = 0.30) in those with restenosis compared with those without. The relative risk of restenosis for apo E4 carriers was 1.11 (95% CI = 0.87-1.42). In apo E4 carriers, restenosis frequency was similar in those also carrying the ACE D allele and those without (28/55 (50.9%) versus 9/16 (56.2%), P = 0.71) and there was no significant increase in restenosis risk in carriers of both the apo E4 and ACE D alleles compared to the rest (odds ratio 1.30, 95% CI 0.68-2.50, P = 0.39). We conclude that in our cohort, the apo E4 allele does not either independently or acting synergistically with the ACE D allele increase the risk of restenosis after PTCA, and that apo E genotyping will not be a useful predictor of risk before the procedure.
