Postural plasma renin activity response in renovascular hypertension is either normal or exaggerated, but does not predict surgical success.
No takes yet. Share an insight, caveat, or question.
Postural PRA testing does not predict surgical success in renovascular hypertension; leaves open its value for patient selection in future studies.
Nielsen et al. (1971) studied this question.
