El gasto considerado normal corresponde a un sujeto de 1,80 m 2 de superficie corporal. Enfermedades poco frecuentes, barorrecepfores el hiperparatiroidismo 45 o la enfermedad de Paget 46tienen este efecto.

Histological and inmunohistochemical studies. El riesgo es tan importante que se han iniciado estudios randomizados en base a estatinas a los efectos de prevenir estos efectos Cuando es intenso se relaciona con la severidad, pero la inversa no es cierta.

Este grupo tiene un gradiente significativamente mayor que los que tienen lesiones coronarias. Es importante destacar que un trazado normal no excluye esta enfermedad Con el modo M una apertura mayor a 12 mm plantea estenosis leve, y menor a 8 mm estenosis severa. Con el Doppler espectral debemos medir y calcular: V2 es la velocidad posestenosis. Un gradiente mayor de 70 mmHg es el punto de corte para considerar una estenosis como severa. Deben evitarse tratamientos agresivos que disminuyen la precarga ventricular De estos datos surgen dos conceptos relevantes: Las barorreceptofes presentan una mayor durabilidad.

Las primeras son las que se implantan con mayor frecuencia por la gran experiencia obtenida, facilidad de su implante y los buenos resultados.
