Abstract
- espanolAntecedentes: el sincope vasovagal (VVS) es una condicion clinica comun que involucra antecedentes geneticos. El papel de los betabloqueantes en el tratamiento es controvertido. Objetivo: El objetivo de este estudio fue investigar el efecto del polimorfismo del gen beta-1 en la terapia con betabloqueantes en pacientes con VVS. Metodos: se incluyeron 123 pacientes que fueron diagnosticados de VVS despues de la prueba de la mesa basculante. Buscamos el polimorfismo Arg389Gly (rs1801253) en el gen del adrenoceptor beta-1. Resultados: En general, 64 pacientes (52%) tenian el genotipo Arg389Arg y 59 pacientes (48%) tenian el genotipo Arg389Gly. Los episodios sincopales de los pacientes con genotipo Arg389Arg fueron mas frecuentes en comparacion con los pacientes con genotipo Arg389Gly (episodios sincopales totales [TSE], 7,9 ± 3,7 frente a 6,4 ± 3,0; p = 0,012). La TSE en pacientes con genotipo Arg389Arg disminuyo significativamente despues de 18 meses de tratamiento con betabloqueantes (7,9 ± 3,7 frente a 3,0 ± 1,4, p Conclusiones: Los resultados de la terapia con betabloqueantes en pacientes con genotipo Arg389Arg sugieren que la fisiopatologia del VVS es una condicion multifactorial, con componentes geneticos, psicologicos y ambientales, por lo que la seleccion del tratamiento puede basarse en el polimorfismo de genes.

The role of beta-blockers in the treatment is controversial. Objective: The aim of this study was to investigate the effect of beta-1 gene polymorphism on beta-blocker therapy in patients with VVS. Methods: We included 123 patients who were diagnosed with VVS after the tilt-table test. We searched for the polymorphism Arg389Gly (rs1801253) in the beta-1 adrenoceptor gene. Results: Overall, 64 patients (52%) had Arg389Arg genotype and 59 patients (48%) had Arg389Gly genotype. The syncopal episodes of patients with Arg389Arg genotype were more frequent compared with patients having Arg389Gly genotype (total syncopal episodes [TSE], 7.9 ± 3.7 vs. 6.4 ± 3.0; p = 0.012). TSE in patients with Arg389Arg genotype decreased significantly after 18 months of beta-blocker treatment (7.9 ± 3.7 vs. 3.0 ± 1.4, p Conclusions: Results of beta-blocker therapy in patients with Arg389Arg genotype suggest that VVS pathophysiology is a multifactorial condition, with genetic, psychological, and environmental components, and therefore, treatment selection can be based on gene polymorphism.
