Low adherence to treatment is an important cause of resistant hypertension. [48] This low adherence to blood pressure treatment is the result of many patients’ generally poor health literacy, costly antihypertensive medications, and inability to accurately follow complex regimens. [49]
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia. This narrowing of the renal artery can impede blood flow to the target kidney , resulting in renovascular hypertension – a secondary type of high blood pressure .
Renal infarction is a medical condition caused by an abrupt disruption of the renal blood flow in either one of the segmental branches or the major ipsilateral renal artery. [3] Patients who have experienced an acute renal infarction usually report sudden onset flank pain , which is often accompanied by fever , nausea , and vomiting .
A retrospective analysis of five million patient records with the US Department of Veterans Affairs system found different types of commonly used antihypertensive medications had very different AD outcomes. Those patients taking angiotensin receptor blockers (ARBs) were 35 to 40% less likely to develop AD than those using other antihypertensives.
English: What is renal artery stenosis? Renal artery stenosis describes a condition where the artery delivering blood to kidney becomes narrowed. Sources: Sattar, H. A. (2013). Fundamentals of Pathology (2013 Edition ed.). Chicago, Il
Familial renal disease is an uncommon cause of kidney failure in dogs and cats. Most causes are breed-related (familial) and some are inherited. Some are congenital (present at birth). Renal dysplasia is a type of familial kidney disease characterized by abnormal cellular differentiation of kidney tissue.
Radioisotopes can differentiate between passive dilatation and obstruction. It is widely used before kidney transplantation to assess the vascularity of the kidney to be transplanted and with a test dose of captopril to highlight possible renal artery stenosis in the donor's other kidney, [12] and later the performance of the transplant.
Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys. RAS is typically diagnosed with duplex ultrasonography of the renal arteries. It is treated with the use of balloon angioplasty and stents, if necessary.
