Plasma Renin Activity Is a Predictive Biomarker of Blood Pressure Response in European but not in African Americans With Uncomplicated Hypertension.

The article reports the response of antihypertensives to the response of Interindividual variability in blood pressure (BP.) Topics discussed include that using systematic-phased approach, plasma renin activity (PRA's) clinical utility was assessed; and categorizing by baseline PRA; and concluded that PRA at the previously established 0.60–0.65 ng/ml/hour cut point is an effective predictive biomarker of BP response in European Americans.
