To test the utility of endoprosthetic treatment for ostial renal artery stenosis, and to examine blood pressure and its treatment, serum creatinine, and restenosis rate, 44 ostial renal stent placements were performed in 30 patients with concomitant coronary artery disease, arterial hypertension, and the indication for angiotensin converting enzyme (ACE) therapy. There was a marked decrease in systolic and diastolic blood pressure (163 ± 30 to 145 ± 17 and 93 ± 18 to 83 ± 10 mm Hg; P < 0.008) with a decrease in number of medication (3.2 ± 0.9 to 2.8 ± 1.0; P = 0.005). In 5 out of 8 patients not receiving an ACE inhibitor, this drug could be added. Serum creatinine changed from 1.46 ± 0.7 mg/dl to 1.39 ± 0.58 mg/dl (P = ns). Three patients showed restenosis (12.5%). Ostial stenting lowers blood pressure, decreases antihypertensive drugs and increases medication flexibility. Cathet. Cardiovasc.

Objective : To provide safety and performance goals for prospective single‐arm trials of bare metal renal artery stenting in patients with resistant hypertension associated with high grade atherosclerotic renal artery stenosis. Background : To date, there have been no US Pre‐Market Approval (PMA) bare metal renal stent device trials which have focused on improvement of blood pressure control as a primary effectiveness endpoint. Methods : Analysis of subject‐level data from three large industry sponsored pre‐market approval (PMA) trials was performed. Hypertensive patients (≥155 mmHg) with a ≥50% atherosclerotic renal artery stenosis were included. Thirty day and 9‐month systolic and diastolic blood pressure measurements, renal function and 9‐month duplex ultrasound assessment of renal artery patency were analyzed. Results : Initial data analysis of 600 patients from the 3 PMA trials identified 286 patients who met inclusion criteria. The mean baseline systolic blood pressure was 177.8 ± 19.3 mmHg with a mean 68.1% diameter renal artery stenosis. Nine months after successful stenting, the mean SBP was 156.7 ± 24.1 mmHg; the 9 month restenosis rate was 14.4%. Conclusion : Based on the statistical modeling of these data and a priori established performance criteria, the co‐primary endpoints of 9 month reduction in blood pressure and in‐stent restenosis are proposed. The reduction in blood pressure will be analyzed as a continuous variable and will be compared to this performance goal. © 2011 Wiley‐Liss, Inc. 相似文献

Prevalence and predictors of renal artery stenosis in Chinese patients with coronary artery disease 总被引:11,自引:0,他引:11

Abstract
Background: Ischaemic nephropathy is currently a major public health issue in atherosclerotic populations. Although atherosclerotic cardiovascular disease in Asia has reached epidemic proportions over the last two decades, there is little published data on the prevalence of atherosclerotic renal artery stenosis (ARAS) in Oriental subjects. Because ARAS may be clinically silent until end-stage renal failure sets in, it is important to identify patients with significant but clinically unsuspected ARAS. ARAS and coronary artery disease (CAD) often coexist.
Aims: The purpose of the present study was to evaluate the prevalence and predictors of ARAS among Chinese patients with CAD.
Methods: A total of 230 consecutive Chinese patients with CAD confirmed by coronary angiography underwent an abdominal aortogram in the same sitting to screen for ARAS. Patient demographics and comorbidities were analysed for any association with ARAS.
Results: A total of 34 (14.8%) patients was found to have significant ARAS. Age and multivessel CAD were independent predictors of ARAS. Hypertension, renal insufficiency, extracranial cerebrovascular disease and female gender were also associated with a higher risk of ARAS but did not independently predict ARAS.
Conclusion: Clinically silent yet angiographically significant ARAS is common among CAD patients. The prevalence and predictors of ARAS among Chinese patients with CAD are similar to those reported for Caucasian subjects. Underlying ARAS should be suspected in CAD patients with such comorbidities as hypertension, renal insufficiency, extracranial cerebrovascular disease, and more so in the elderly and those with multivessel disease.

Idiopathic mediastinal fibrosis (IMF) is an uncommon clinical condition and the manifestations of this disease vary from a relatively benign disorder with minor symptoms to severe pulmonary vascular occlusion leading to mortality, commonly presenting a diagnostic and therapeutic challenge. Here, we present the case of a Taiwanese woman with obstruction of the left pulmonary veins and artery and stenosis of the left main coronary artery (LMCA) resulting from IMF. To our knowledge, this is the first reported case of IMF successfully treated with percutaneous balloon angioplasty with stent placement for the LMCA stenosis. © 2011 Wiley Periodicals, Inc. 相似文献
