Relationship between Plasma Aldosterone Levels and Left Ventricular Mass in Hypertensive Africans

International Journal of Hypertension, 2013
Background. Hypertension is the most common cardiovascular disease worldwide and is a major cause of morbidity and mortality. Studies have suggested that the activity of the renin-angiotensin-aldosterone system play a major role in the target organ ...

Twenty-Four-Hour Urinary Aldosterone Predicts Inappropriate Left Ventricular Mass Index in Patients with Primary Aldosteronism

The Scientific World Journal, 2013
Objective. Primary aldosteronism (PA) is associated with inappropriate left ventricular hypertrophy (LVH) in relation to a given gender and body size. There is no ideal parameter to predict the presence of LVH or inappropriate LVH in patients with PA. We

Effect of a SGLT2 inhibitor on the systemic and intrarenal renin–angiotensin system in subtotally nephrectomized rats

Journal of Pharmacological Sciences, 2018
We aimed to examine the effects of a sodium glucose co-transporter 2 (SGLT2) inhibitor on systemic and intrarenal renin–angiotensin system (RAS) in subtotally nephrectomized non-diabetic rats, a model of chronic kidney disease (CKD).

Alterations in vascular function in primary aldosteronism - a cardiovascular magnetic resonance imaging study [PDF]

, 2014
Introduction: Excess aldosterone is associated with increased cardiovascular risk. Aldosterone has a permissive effect on vascular fibrosis. Cardiovascular magnetic resonance imaging (CMR) allows study of vascular function by measuring aortic ...

Activation of the Human Angiotensin-(1-12)-Chymase Pathway in Rats With Human Angiotensinogen Gene Transcripts

Frontiers in Cardiovascular Medicine, 2019
Angiotensin-(1-12) [Ang-(1-12)], an alternate substrate for tissue angiotensin II (Ang II) formation, underscores the importance of alternative renin-independent pathway(s) for the generation of angiotensins.

PLASMA RENIN ACTIVITY IN RENOVASCULAR HYPERTENSION

Japanese Circulation Journal, 1971
Dynamics of plasma renin activity (PRA) in peripheral and renal vein was studied in 22 patients with various types of renovascular hypertension. Significant elevation of resting peripheral vein PRA (PPRA) was observed in 7 out of 8 cases with unilateral main renal artery stenosis (type I).

Bi-directional actions of estrogen on the renin-angiotensin system

Brazilian Journal of Medical and Biological Research, 1999
Estrogen stimulates the renin-angiotensin system by augmenting both tissue and circulating levels of angiotensinogen and renin. We show, however, that angiotensin converting enzyme (ACE) activity in the circulation and in tissues is reduced in two animal

Characterization of resistant hypertension: Association between resistant hypertension, aldosterone, and persistent intravascular volume expansion [PDF]

, 2008
Background: Resistant hypertension is a common clinical problem and greatly increases the risk of target organ damage. Methods: We evaluated the characteristics of 279 consecutive patients with resistant hypertension (uncontrolled despite the use of 3 ...

Effect of Dehydration on Plasma Renin Activity

Japanese Circulation Journal, 1967
To elucidate the effect of plasma volume on renin secretion, plasma renin activity was measured in 10 normal and hypertensive subjects during water test of VOLHARD. Water deprivation resulted in a significant increase in plasma renin activity, plasma sodium concentration and hematocrit in them except 2 patients with primary aldosteronism. Estimation of
