Objective: Coronary slow flow phenomenon (CSFP) is characterized by the decreased rate of contrast progression in epicardial coronary arteriesin the absence of significant coronary stenosis. Mounting evidence has showed a significant association between inflammation and CSFPseverity. This study aimed to evaluate possible associations between interleukin-1 receptor antagonist (IL-1ra) gene variable number tandemrepeat (VNTR), IL-1β -511 single nucleotide (SNP), and IL-1β+3954 SNP mutations with CSFP.Methods: Forty-eight patients with CSFP and 62 controls with angiographically normal coronary arteries were prospectively enrolled in the study.Genotypes were assessed using the polymerase chain reaction (PCR)-based restriction fragment length polymorphism (PCR-RFLP) technique.Results: Homozygote genotype for allele 2 of+3954 C>T 2/2 genotype was significantly more frequent in patients with CSFP than in the controlgroup, whereas 1/2 genotype was more frequent in the control group (35.4% versus 14.5% for 2/2 genotype and 25% versus 35.5% for 1/2 genotypein CSFP and control groups, respectively, X2=6.6; p=0.04). The allelic frequency of allele 2 of this polymorphism was significantly higher inthe CSFP group than in the control group (47.9% versus 28.6% in the control group, X2=5.6; p=0.02). However, there was no significant differencewith regard to genotype or allelic frequencies of IL-1ra VNTR or IL-1β -511 SNP polymorphisms between patients with CSFP and controls.Conclusion: IL-1β+3954 SNP mutations are significantly more common in patients with CSFP. It may suggest that the tendency for inflammationmay contribute to the presence of this phenomenon.
