Condition(s) targeted: Hypertension
Intervention: clinical hypertension specialist-no specific med. Any anti-hypertension meds. (Drug); renin guided therapeutics-no specific med. Any anti-hypertensive med. (Drug)

Plasma renin values determine whether volume or vasoconstrictor (renin) factors predominate
in elevating blood pressure and are useful in selecting effective antihypertensive
The researchers hypothesize that:
1. Plasma renin-guided therapeutics will improve systolic and diastolic blood pressure
control in patients with untreated hypertension as well as in patients with treatment
refractory or resistant hypertension that are managed by Clinical Hypertension
2. Renin-guided therapeutics will reduce the number of medications required to maintain
blood pressure control to <140/90 mmHg in hypertensive patients receiving 3 or more
medications, while under the care of a Clinical Hypertension Specialist.
3. Renin-guided therapeutics selection will reduce the total cost of antihypertensive care
provided by Clinical Hypertension Specialists.

Study design: Treatment, Non-Randomized, Open Label, Parallel Assignment
Hypertension affects ~25% of adults. The prevalence of hypertension and related
complications is greater among the elderly, obese, and ethnic minorities. Unfortunately,
hypertension control rates remain in the 25% range and are often significantly lower for the
high-risk groups noted. 1 Since the high-risk groups are growing more rapidly than the
general population, the prevalence of hypertension and associated morbidity and mortality
will probably increase sharply in the years ahead unless successful strategies are
implemented for dramatically improving blood pressure control.
Direct measurements of plasma renin reflect the relative balance between volume (V) and
vasoconstrictor (renin [R]) factors underlying the elevated blood pressure in patients with
essential hypertension. 2 While many antihypertensive medications have effects on both the
volume (V) and vasoconstrictor (renin [R]) components of elevated blood pressure, one or the
other usually predominates
