Should the blood pressure or the blood vessel be the target of therapy?

Measured blood pressure is an insensitive and moderately nonspecific guide to the presence of vascular or cardiac diseases likely to progress to cardiovascular morbid events. Since the goal of the diagnosis and treatment of hypertension is to prevent or forestall such morbid events, blood pressure measurements should be supplemented by studies of the health of the cardiovascular system in defining the syndrome of hypertension and in monitoring its response to therapy.
