Ethnic differences in aortic aneurysm and peripheral vascular disease

Section 5. Atherosclerotic Peripheral Vascular Disease and Aortic Aneurysm

Profiles in Aortic and Peripheral Vascular Disease

The indications for revascularization of the vertebral arteries are symptoms of vertebrobasilar insufficiency, namely, dizziness, visual disturbances, and confusion or coma. There is a great deal of variation from patient to patient in the severity of lesions causing symptoms . In some patients the degree of stenosis may be severe yet the patient may experience minimal or no symptoms; in others...

Atherosclerotic Peripheral Vascular Disease Symposium II: controversies in abdominal aortic aneurysm repair.

Abdominal aortic aneurysms (AAAs) are the result of a progressive degenerative process characterized by elastin depletion and inflammatory changes of the aortic wall. The process leads to gradual enlargement and a localized weakening of the aorta, with eventual rupture. Risk factors include age, sex, family history, and smoking.1 The normal aortic diameter varies with age, sex, and body size. A...

Gender differences in experimental aortic aneurysm formation.

OBJECTIVE It is hypothesized that a male predominance, similar to that in humans, persists in a rodent model of experimental abdominal aortic aneurysm (AAA) via alterations in matrix metalloproteinases (MMPs). METHODS AND RESULTS Group I experiments were as follows: elastase perfusion of the infrarenal aorta was performed in male (M) and female (F) rats. At 14 days, aortas were harvested for ...

Risk Stratification of Patients with Peripheral Arterial Disease and Abdominal Aortic Aneurysm Using Aortic Augmentation Index

BACKGROUND Central augmentation index (cAIx) is an indicator for vascular stiffness. Obstructive and aneurysmatic vascular disease can affect pulse wave propagation and reflection, causing changes in central aortic pressures. AIM To assess and compare cAIx in patients with peripheral arterial disease (PAD) and / or abdominal aortic aneurysm (AAA). METHODS cAIx was assessed by radial applana...
