Why the study?
Does upright posture and furosemide administration affect plasma renin activity and angiotensin II levels in patients with various forms of hypertension?
Does upright posture and furosemide administration affect plasma renin activity and angiotensin II levels in patients with various forms of hypertension?
The response of plasma renin activity and angiotensin II to upright posture and furosemide administration can serve as a diagnostic index for primary aldosteronism and renovascular hypertension.
