A Pilot Study of Plasma Renin Activity Guided vs Generic Combination Therapy for Hypertension
| Status: | Completed |
|---|---|
| Conditions: | High Blood Pressure (Hypertension) |
| Therapuetic Areas: | Cardiology / Vascular Diseases |
| Healthy: | No |
| Age Range: | 18 - Any |
| Updated: | 4/21/2016 |
| Start Date: | October 2012 |
| End Date: | July 2014 |
The purpose of this study is to investigate the effect of plasma renin activity-guided
therapy for determining hypertension treatment. Plasma renin is an enzyme in your blood that
can be measured to determine your hypertension subtype. Once the subtype is known, doctors
can prescribe specific medications to target your specific hypertension subtype. This study
will investigate whether targeting the specific hypertension subtype helps to achieve blood
pressure control sooner and with fewer medications compared to a standard fixed dose
combination therapy.
