Hipertrofia ventricular izquierda y variabilidad de la presión arterial en la hipertensión arterial esencial

Abstract

Fundamento y objetivo Las fluctuaciones de la presion arterial (PA) parecen influir en el desa-rrollo de lesiones de organo diana en la hipertension arterial, si bien su relacion con la hipertro-fia ventricular izquierda (HVI) es objeto de discusion. El objetivo de este estudio ha sido eva-luar la relacion entre la variabilidad de la PA, definida mediante distintos instrumentos de medida, y la HVI en un grupo de pacientes hipertensos esenciales. Pacientes y metodo Se estudio a 43 pacientes hipertensos que nunca habian recibido trata-miento. La variabilidad de la PA se evaluo utilizando monitorizacion continua no invasiva de 24 h latido a latido a traves de un pletismografo digital (Portapres), asi como monitorizacion discontinua de 24 h mediante un aparato oscilometrico automatico (MAPA). A todos los pa-cientes se les practico un ecocardiograma con el fin de detectar la presencia de HVI. Resultados Se detecto HVI en 30 de los 43 pacientes del estudio (70%). Los valores de PA sistolica fueron significativamente mas elevados en los pacientes con HVI, tanto en la consulta (167,7 [19,5] frente a 156,7 [14,9] mmHg; p = 0,032) como en la media de 24 h obtenida a traves de MAPA (146,6 [15,7] frente a 131,9 [15,1] mmHg; p = 0,003) y en la media de 24 h obtenida por monitorizacion continua latido a latido (147,5 [21,3] frente a 135,7 [14,2] mmHg; p = 0,046) respecto a los que no tenian HVI. No se observaron diferencias significati-vas en cuanto al descenso nocturno de PA en los pacientes con o sin HVI. Igualmente, las des-viaciones estandar de 24 h obtenidas por MAPA o los estimadores de variabilidad a largo y cor-to plazo obtenidos por monitorizacion continua no mostraron diferencias significativas entre pacientes con y sin HVI. Conclusion El presente estudio indica que la presencia de HVI en el paciente hipertenso esta relacionada, fundamentalmente, con la elevacion de los valores de PA sistolica pero no con la variabilidad de la PA a corto ni a largo plazo.
