There are no studies investigating the effect of the contrast infusion on the sensitivity and specificity of the main Doppler criteria of renal artery stenosis (RAS). Our aim was to evaluate the accuracy of these Doppler criteria prior to and following the intravenous administration of
This study examined body fluid volumes, the pressor responses to norepinephrine (NE), and the cardiovascular responses to NE before and during infusion of an angiotensin II (ANG II) antagonist in two-kidney rabbits with unilateral renal artery stenosis (RAS) of 3 and 30 day duration. Three separate
We previously showed that renal artery stenosis (RAS) was commonly found in patients with cardiovascular disease (CVD) such as myocardial infarction, stroke, or abdominal aneurysm. The aim of the present study was to evaluate the incidence and risk factors for RAS in patients with severe carotid
OBJECTIVE
Atherosclerotic renal artery stenosis (ARAS) is frequently detected in patients with resistant hypertension (RHTN), but the evidence supporting the utility of renal revascularization in these patients is limited. This prospective, observational study investigates the outcomes of renal
The goal of this review is to summarize recent advances in the field and highlight important new insights from the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) trial regarding the optimal management of patients with renal artery stenosis (RAS).
The CORAL trial demonstrated that
BACKGROUND
Transplant renal artery stenosis (TRAS) is an important cause of hypertension and renal allograft dysfunction occurring in kidney transplant recipients. However, conflicting predisposing risk factors for TRAS have been reported in the literature.
OBJECTIVE
The aim of the present study was
The aim of this study was to evaluate the effect of renal artery stenosis (RAS) correction in hypertensive patients on 24 h SBP, 24 h DBP, creatinine clearance (GFR), urinary albumin excretion (UAE) and LV morphology and mass (LVMI). A total of 61 hypertensive patients with RAS undergoing PTRA
OBJECTIVE
MR angiography is proving to be a useful clinical study for the diagnosis of vascular disorders of renal arteries. However, its utility in terms of stenosis characterization is still limited. Renal perfusion could provide supplemental information that could allow for a comprehensive
It is important to identify patients at risk for atherosclerotic renal artery stenosis because renal artery stenosis is a progressive disease and a potentially correctable problem. To determine the risk factors for atherosclerotic renal artery stenosis, we performed renal arteriography at the time
Renal artery stenosis (RAS) is one of the main reasons of renovascular hypertension and its pathogenesis remains unclear. In this study, we aimed to investigate histopathological characteristics in a rat model of RAS. Sprague-Dawley (SD) male rats were randomly divided into unilateral RAS group
We investigated the impact of renal function on outcomes after percutaneous transluminal angioplasty.
A total of 139 hypertensive patients with atherosclerotic renal artery stenosis (mean age, 70 years, 80.6% men) who underwent renal percutaneous transluminal angioplasty were included. Renal
To perform a post-hoc analysis of the Nephropathy Ischemic Therapy (NITER) trial, which enrolled patients with atherosclerotic renal artery stenosis, to evaluate whether medical therapy plus stent placement is superior to medical therapy alone in patients without elevated albuminuria.
Data from 51
OBJECTIVE
Renal dysfunction occurs occasionally after the repair of abdominal aortic aneurysm (AAA), and preoperative renal function is considered as one of the potential causes. The present study was designed to evaluate and compare renal function and risk factors of AAA patients with those of
We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2011. The major guideline changes this year are: (1) a recommendation was made for using comparative risk analogies when communicating a patient's cardiovascular risk;
Although current guidelines recommend the use of statins for severe atherosclerotic renal artery stenosis (ARAS), the renal protection of intensive lipid-lowering therapy in patients with ARAS who underwent stent placement remains uncertain. The aim of this study was to compare the
