Why the study?
Does passive tilting improve the diagnostic accuracy of the renal venous PRA ratio for predicting surgical curability in hypertensive patients with renal artery stenosis?
Does passive tilting improve the diagnostic accuracy of the renal venous PRA ratio for predicting surgical curability in hypertensive patients with renal artery stenosis?
Determination of plasma renin activity after passive tilting provides a more accurate indicator for predicting surgical curability in patients with renal artery stenosis compared to the prolonged recumbent position.
No takes yet. Share an insight, caveat, or question.
May enhance renal venous PRA ratio accuracy for RAS; leaves open prospective validation for surgical curability prediction.
Morimoto et al. (1977) studied this question.
