Sobre nuestros pacientes con ERCA, existen otros beneficios en esta poblacion, con algunas pruebas especificas como el indice tobillo-brazo o el analisis de la onda de pulso arterial (arteriograph), que nos permitira detectar el paciente de mayor riesgo con calcificacion de rigidez a nivel del arbol vascular (20).
Arteriograph (TensioMed Kft., Hungary) was used to measure aortic pressure indices, aortic PWV (PWVao), and aortic augmentation index (AIx), with the subject lying supine for at least 10 minutes in a temperature-controlled room (22 [+ or -] 2[degrees]C).
To the best of our knowledge, the largest databases of RIs of cSBP and cAIx in pediatrics come from Hungary  and Germany, in which the Arteriograph and Mobil-O-Graph System were respectively used .
The vessels are studied in an isobaric arteriograph. Arterial diameter measurements are made over a range of pressures (20-120mmHg) to assess the vessels' myogenic reactivity responses (n=6 per group).
The RHR (beat/min) and blood pressures (mmHg) were calculated in accordance with suggestions of the European Society of Hypertension (ESH).19 The volunteers, who took a rest in the supine position at least five minutes, were evaluated by the commercially available TensioMedTM Arteriograph (TensioMed Ltd, Hungary) to calculate these parameters.
Peripheral systolic/diastolic BP and the central aortic systolic blood pressure (SBPao, representing the actual cardiac pressure load) were measured using an Arteriograph v.22.214.171.124 (TensioMed Ltd, Budapest, Hungary) instrument.
