Impaired Renal Function and Cerebrovascular Disease

Impaired Cerebrovascular Function in Coronary Artery Disease Patients and Recovery Following Cardiac Rehabilitation

Coronary artery disease (CAD) poses a risk to the cerebrovascular function of older adults and has been linked to impaired cognitive abilities. Using magnetic resonance perfusion imaging, we investigated changes in resting cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) to hypercapnia in 34 CAD patients and 21 age-matched controls. Gray matter volume (GMV) images were acquired an...

Impaired renal function in acute myocardial infarction.

Impaired renal function is a risk factor for cardiovascular disease and an adverse prognostic factor in patients with established cardiovascular disease. In addition, with current widespread use of invasive procedures in the treatment of acute myocardial infarction, contrast-induced nephropathy is a growing problem in this patient population. In acute myocardial infarction, impaired renal funct...

Allopurinol in patients with impaired renal function.

The relationship between impaired retinal vascular reactivity and renal function in patients with degenerative vascular disease.

In hypertension and diabetes retinal vascular changes which are evident on fundiscopic examination are usually accompanied by renal vascular changes which are evident on microscopic examination. It has been found that the retinal vessels of most patients with hypertension or diabetes fail to constrict normally when the blood oxygen tension is elevated. This investigation evaluates the clinical ...

Anticoagulation in patients with impaired renal function and with haemodialysis.

Patients with impaired renal function are exposed to an increased risk for bleeding complications depending on the amount of the anticoagulant eliminated by the kidneys. The elimination of unfractionated heparins, vitamin K antagonists and argatroban is only minimally influenced by a reduced renal function. Low-molecular weight heparins, fondaparinux, danaparoid, hirudins and nonvitamin K antag...
