RESUMEN
Introducción y

objetivos:

El objetivo del estudio es evaluar el efecto de aliskireno en la rigidez aórtica del paciente con síndrome de Marfan (SM).

Métodos:

Se reclutó a 28 pacientes con SM (media ± desviación estándar de edad, 32,6 ± 10,6 años) entre noviembre de 2009 y octubre de 2014. Todos estaban tratados con atenolol como terapia estándar con bloqueadores beta. Mediante un proceso prospectivo de aleatorización, se asignó a los participantes a tratamiento con aliskireno (150-300 mg/día vía oral) o sin tratamiento con aliskireno (controles negativos) en un diseño de etiquetado abierto. Se examinaron al inicio y a las 24 semanas la distensibilidad aórtica central y la velocidad de la onda de pulso (PWV) cuantificadas con resonancia magnética (RM), la PWV periférica, la presión aórtica central y el índice de aumento medidos por tonometría y la dilatación aórtica por ecocardiografía. El objetivo primario fue la distensibilidad aórtica central por RM.

Resultados:

En el análisis de la diferencia entre el examen basal y a las 24 semanas en el grupo tratado frente a los controles negativos, la distensibilidad aórtica central (general; p = 0,26) y la PWV central (0,2 ± 0,9 frente a 0,03 ± 0,7 m/s; p = 0,79) medidas con RM no fueron significativas. La presión sistólica central en la aorta era de 14 mmHg, menor en los pacientes tratados que en los controles (p = 0,09). Se observó una reducción significativa de la PWV periférica (brazo-tobillo) en el grupo tratado (-1,6 m/s) respecto a los controles (+0,28 m/s; p = 0,005).

Conclusiones:

En los pacientes con SM, la incorporación de aliskireno a los bloqueadores beta no mejora la rigidez de la aorta central a las 24 semanas de tratamiento
ABSTRACT
Introduction and

objectives:

The aim of this study was to evaluate the effect of aliskiren on aortic stiffness in patients with Marfan syndrome (MS).

Methods:

Twenty-eight MS patients (mean age ± standard deviation 32.6 ± 10.6 years) were recruited from November 2009 to October 2014. All patients were receiving atenolol as standard beta-blocker therapy. A prospective randomization process was performed to assign participants to either aliskiren treatment (150-300 mg orally per day) or no aliskiren treatment (negative control) in an open-label design. Central aortic distensibility and central pulsed wave velocity (PWV) by magnetic resonance imaging (MRI), peripheral PWV, central aortic blood pressure and augmentation index by peripheral tonometry, and aortic dilatation by echocardiography were examined initially and after 24 weeks. The primary endpoint was central aortic distensibility by MRI.

Results:

In analyses of differences between baseline and 24 weeks for the aliskiren treatment group vs the negative control group, central distensibility (overall; P = .26) and central PWV (0.2 ± 0.9 vs 0.03 ± 0.7 [m/s]; P = .79) by MRI were not significantly different. Central systolic aortic blood pressure tended to be lower by 14 mmHg in patients in the aliskiren treatment group than in the control group (P = .09). A significant decrease in peripheral PWV (brachial-ankle PWV) in the aliskiren treatment group (-1.6 m/s) compared with the control group (+0.28 m/s) was noted (P = .005).

Conclusions:

Among patients with MS, the addition of aliskiren to beta-blocker treatment did not significantly improve central aortic stiffness during a 24-week period
