Moderate exercise may benefit people with peripheral artery diseaseDecember 26th, 2008 - 1:26 pm ICT by ANI
Washington, Dec 26 (ANI): A new research has shown that regular, moderate exercise can go a long way to relieving the symptoms of peripheral artery disease (PAD).
It is known that poor diet and lack of exercise can lead to dangerous deposits of fatty plaques in arteries.
But it is not just the heart that is affected blood flow can be blocked to the legs too, leading to pain when walking, immobility and even in extreme cases, amputation.
Surgical intervention can sometimes help, but the prognosis is not good, so the new study seems to be significant.
When a major artery in the leg becomes blocked, the body naturally seeks another route for the blood to pass through by expanding and multiplying the surrounding smaller blood vessels in the area, called collateral blood flow.
For the study, researchers examined rats with a blocked femoral artery and found that collateral blood flow was much more effective in restoring normal muscle function in rats that were put on regular exercise training.
The collateral vessels themselves were larger and less prone to constriction a problem exacerbated with PAD than in sedentary animals.
Surprisingly, the function of blood vessels downstream of the blockage also changed, making them more efficient.
Researchers predict that a suitable exercise programme would delay the onset of pain and increase mobility for people suffering with PAD.
Our findings raise the potential that new collateral vessels, that can develop in patients with PAD who are physically active, will function effectively to help minimize the consequences of the original vascular obstruction, the Science Daily quoted Dr Ronald Terjung, as saying.
The study is published in The Journal of Physiology. (ANI)
