Arterial stiffness is measured by carotid–femoral pulse wave velocity (cfPWV) or brachial–ankle PWV (baPWV). [ 7 ] cfPWV is the standard for measuring large artery stiffness in Europe. [ 7 ] For baPWV, general cutoff values for cardiovascular risk assessment are <1400 cm/s for low risk, 1400–1800 cm/s for intermediate risk, and >1800 cm/s ...
Other causes include vasculitis and in situ thrombosis related to hypercoagulable states. [53] Additional mechanisms of peripheral artery disease include arterial spasm and fibromuscular dysplasia. [19] The cause and pathophysiology of arterial spasm are not fully understood, but it is hypothesised that they can occur secondary to trauma. [54]
The arterial compliance - the amount of tension produced per stretch of arteries, decreases with age, and the stiffness of arteries increases with age. [3] The structural change in blood vessels causes the elderly to be more susceptible to hypertension, which leads to complications in arteries, the heart and even the brain. [citation needed]
The theory of the velocity of the transmission of the pulse through the circulation dates back to 1808 with the work of Thomas Young. [9] The relationship between pulse wave velocity (PWV) and arterial wall stiffness can be derived from Newton's second law of motion (=) applied to a small fluid element, where the force on the element equals the product of density (the mass per unit volume ...
There is a recurrent acute and chronic inflammation and thrombosis of arteries and veins of the hands and feet. The main symptom is pain in the affected areas, at rest and while walking (claudication). [1] The impaired circulation increases sensitivity to cold. Peripheral pulses are diminished or absent. There are color changes in the extremities.
Heavy legs is a condition described as an unpleasant sensation of pain and heaviness in the lower limbs. Symptoms include legs feeling weighted, stiff, and tired. Heavy legs can be caused by a wide-ranging collection of disorders including but not restricted to varicose veins, peripheral artery disease, restless legs syndrome, multiple sclerosis, venous insufficiency.
This is probably due to vascular calcification causing increased arterial stiffness, increased pulse pressure and resulting in exaggerated damage to the heart and kidneys. [12] The clinical symptoms of Mönckeberg's arteriosclerosis are similar to giant cell arteritis in which the two can be mistakenly interchanged.
Diabetic foot ulcer is a breakdown of the skin and sometimes deeper tissues of the foot that leads to sore formation. It is thought to occur due to abnormal pressure or mechanical stress chronically applied to the foot, usually with concomitant predisposing conditions such as peripheral sensory neuropathy, peripheral motor neuropathy, autonomic neuropathy or peripheral arterial disease.
