The Effect of Balloon Angioplasty on Hypertension in Atherosclerotic Renal-Artery Stenosis

Abstract

In the treatment of patients with hypertension and renal-artery stenosis, angioplasty has little advantage over antihypertensive-drug therapy.

Renovascular disease in patients with hypertension: detection with duplex ultrasound

“…Identification of renal artery stenosis still seems useful since surgical or percutaneous treatment of these lesions may improve blood pressure control and/or stabilise renal function, even though the latter has been disputed in a recent publication. 14 Numerous diagnostic tests have been proposed to identify patients with renovascular disease. However, none of them has received widespread clinical acceptance.…”

The effect of treatment on health-related quality of life in patients with hypertension and renal artery stenosis

“…7 Besides treatment with medication, patients with hypertension and renal artery stenosis can be treated by percutaneous transluminal renal angioplasty, which may lead to improvement or even cure of hypertension. 8 In our trial on diagnosis and treatment of patients with hypertension and renal artery stenosis, we found that the patients who were treated with angioplasty needed less antihypertensive drugs to control blood pressure than the patients who were treated with medication only 9 ( Table 1). Since it has been demonstrated that patients who use less antihypertensive medication report a better health status, 10 the patients in our trial who received angioplasty may have experienced an improvement in their quality of life compared to the patients who received medication only.…”

“…The patients were randomly allocated to balloon angioplasty (n ¼ 56) or to increased antihypertensive drug therapy (n ¼ 50). 9 The primary outcome of the trial was diastolic blood pressure. Quality of life was measured as a secondary outcome measure.…”

Angioplasty for atheromatous renal artery stenosis: current knowledge and trial results awaited

“…Only three such trials have been published so far and all were quite small. [4][5][6] Of the patients randomised to PCTA, only a tiny minority underwent stent insertion. In general the improvement in blood Table 1 Question (with regard to angioplasty and stenting) Answer…”
