Resumen

La presión arterial diastólica (PAD) braquial, en relación con la presión arterial sistólica (PAS) braquial, es un útil marcador de la presión arterial (PA) central, ya que no está distorsionada por la amplificación de la presión. Por el contrario, una PAD baja puede ser un marcador temprano del aumento del gasto cardíaco/ volumen sistólico y/o rigidez arterial en los adultos jóvenes y un marcador tardío de rigidez ventricular y arterial en los ancianos. Además, una PAD elevada es, a cualquier edad, un marcador del aumento de resistencia vascular periférica (típico de la hipertensión arterial idiopática en adolescentes y adultos jóvenes) y cuando está gravemente elevada sugiere causas secundarias de hipertensión y urgencia/crisis hipertensiva, especialmente en ancianos. La hipertensión diastólica muy grave debe considerarse una señal de alarma, tanto para realizar un diagnóstico rápido como para aplicar un tratamiento antihipertensivo agresivo y eficaz.

Brachial diastolic blood pressure (DBP), in relation to brachial systolic blood pressure (SBP), is a useful marker of central blood pressure (BP) because it is not distorted by pressure amplification. Discordantly low DBP may be an early marker of increased cardiac output/stroke volume and/or arterial stiffness in young adults and a late marker of ventricular-arterial stiffness in the elderly. Discordantly elevated DBP at any age is a marker of increased peripheral vascular resistance -typical of essential hypertension in adolescents and young adults- and when severely elevated suggestive of urgent/emergent and secondary causes of hypertension, especially in the elderly. Very severe diastolic hypertension should raise a "red flag", both for prompt diagnosis and for aggressive and effective antihypertensive therapy.
