title: Candidate genetic markers and the risk of restenosis after coronary angioplasty.
abstract: The aim of the present study was to test for possible associations between candidate gene polymorphisms and the risk of restenosis and recurrent restenosis after percutaneous transluminal coronary angioplasty (PTCA) without stenting. We followed up 511 PTCA patients, and restenosis and recurrent restenosis were defined according to angiographical criteria. Genotyping of the beta-fibrinogen -455 G/A, glycoprotein (GP) IIIa PlA1/PlA2, plasminogen activator inhibitor-1 (PAI-1) 4G/5G, factor V Leiden 1691 G/A, tumour necrosis factor alpha (TNFalpha) -238 G/A, TNFalpha -308 G/A, interleukin (IL)-1alpha -889 C/T, IL-1beta -511 C/T, methylenetetrahydrofolate reductase (MTHFR) 677 C/T and endothelial nitric oxide synthase (eNOS) 4 b/a gene polymorphisms was performed by PCR and restriction-fragment-length-polymorphism-based techniques. One hundred and sixty patients (31.3%) developed restenosis and in 130 of these patients, of whom 123 were available for analysis, a second PTCA without stenting was performed. Of these patients, 35 (28.5%) developed recurrent restenosis. None of the investigated genotypes were associated with the risk of restenosis or recurrent restenosis after PTCA. The degree of stenosis before and immediately after PTCA and the severity of the lesion were independent predictors for restenosis after PTCA. In conclusion, there was no association between the beta-fibrinogen -455 G/A, GP IIIa PlA1/A2, PAI-1 4G/5G, factor V Leiden 1691 G/A, TNFalpha -238 G/A, TNFalpha -308 G/A, IL-1alpha -889 C/T, the IL-1beta -511 C/T, MTHFR 677 C/T and eNOS 4 b/a gene polymorphisms and the risk of restenosis after PTCA as well as recurrent restenosis after repeated PTCA.
