CODYETAL. EDITORIALCOMMENT

Therapeuticimplications.As stated in a now classic clinical review (I), “truly resistant” hypertension is not that common in the era of effective pharmacologic therapy. Although practicingclinicians welcome reports of “effective monotherapy” of hypertension in the hope of achieving favorable blood pressure control at minimal cost and morbidity, the reality of clinical practice is that ,nany patients continue to require several agents for blood pressure control. The current study by Julien et al. (6) adds further convincing evidence to the concept that blood pressure reduction alone may not be a sufficientend point of antihy pertensive therapy. A combination of therapies that ameliorates target organ abnormalities may be preferable, particularly by blocking adverse contributions of neurohormonal pathways. The evidence for the adverse influence of the sympathetic nervous system and renin-angiotensin system on left ventricular hypertrophy continues to increase (B-10). Unfortunately, these abnormalities are often best addressed in experimental studies that do no: closely mimic human resistant hypertension. Nonetheless, the observations and implications from drug interventions specifically targeted toward neurohormonal pathways is very convincing. “Resistant hypertension,” defined as the requirement of two or more antihypertensive drugs for blood pressure control, will continue to include a significant proportion of the hypertensive population. Therefore, well defined and executed studies such as that by Julien and coworkers (6)

will help delineate pragmatic and clinically relevant a proaches to effective and antihypertensive the
