ABSTRACT

Objective:

The aim of this study was to test for association between MHC2TA gene polymorphisms and risk for restenosis after coronary stent placement in a group of Mexican patients.

Methods:

The MHC2TA-168A>G (rs3087456), 1614C>G (rs4774), and 2536G>A (rs2229320) single nucleotide polymorphisms were genotyped using 5' exonuclease TaqMan genotyping assays in a group of 202 patients, who underwent coronary artery stenting. Basal and procedure coronary angiography were analyzed, looking for angiographic predictors of restenosis and follow-up angiography was performed to screen for binary restenosis.

Results:

The results obtained in this study showed that the frequency of the three polymorphisms studied was similar in patients with and without restenosis. Univariate analysis showed that the use of drug-eluting stent (DES) reduces the risk of developing restenosis (p < 0.001, OR = 0.26). In contrast, the diameter< 2.5 mm of the stent and bifurcations increased the risk of developing restenosis (p = 0.049, OR = 1.74 and p = 0.041, OR = 1.8).

Conclusion:

The present study suggests that the MHC2TA polymorphisms are not involved in the risk of developing restenosis after coronary stent placement.
RESUMEN

Objetivo:

El propósito de este estudio fue evaluar la asociación de los polimorfismos del gen MHC2TA y el riesgo de desarrollar reestenosis, después del implante de stent coronario en un grupo de pacientes mexicanos.

Métodos:

Los polimorfismos de un solo nucleótido MHC2TA-168A>G (rs3087456), 1614C>G (rs4774) y 2536G>A (rs2229320), se determinaron en un grupo de 202 pacientes tratados con stent coronario. Los polimorfismos fueron evaluados utilizando ensayos de genotipificacion Taq-Man 5' exonucleasa. El procedimiento basal y la búsqueda de predictores de reestenosis fueron analizados por medio de angiografía coronaria, y seguimiento angiográfico con el fin de detectar reestenosis binaria.

Resultados:

Los resultados obtenidos en este estudio mostraron que la distribución génica de los tres polimorfismos estudiados fue muy similar, en pacientes con o sin reestenosis. Sin embargo, el análisis univariado mostró que el uso de los stent medicados reducen el riesgo de desarrollar reestenosis (p < 0.001, OR = 0.26). En contraste, con las bifurcaciones y el diámetro < 2.5 mm del stent que se incrementa el riesgo de desarrollar reestenosis (p = 0.049, OR = 1.74 y p = 0.041, OR = 1.8).

Conclusión:

El presente estudio sugiere que los polimorfismos del gen MHC2TA no están asociados con el riesgo de desarrollar reestenosis, después del implante de stent coronario.
