Abstract





Purpose: To evaluate the association between common single nucleotide polymorphisms (SNPs) in angiotensin converting enzyme (ACE) gene and the risk of in-stent restenosis (ISR) and/or the response to angiotensin converting enzyme inhibitor ACEI in individuals with stable coronary artery disease (CAD) after stent implantation.


Methods: The total population of this study consisted of 200 Egyptian individuals divided into 2 groups - in-stent restenosis (ISR) and non ISR group). Genomic DNA was withdrawn from EDTA whole blood applying a spin column approach and ACE gene insertion/deletion (I/D) polymorphisms were determined by polymerase chain reaction (PCR).


Results: Carriers of allele D of ACE gene were significantly more liable to ISR occurrence. However, carriers of allele I were significantly more liable to ISR occurrence after administration of ACEI. There is a negative interaction between DD genotype of ACE gene and ACEI administration on ISR after percutaneous coronary intervention (PCI). However, there is a positive interaction between II and ID genotype of ACE gene and ACEI administration on ISR after PCI with bare metal stents (BMS).


Conclusion: It is beneficial to implement ACEI in therapeutic regimen in individuals with ID or II genotypes of ACE gene, especially with BMS implementation.
