A $3.7 million government grant was recently awarded to University Health System researchers to fund their studies of diagnostic tools and drug treatment for peripheral arterial disease, or PAD.
The grant, from the National Heart Lung and Blood Institute of the National Institutes of Health, will pay for a five-year study of PAD physiology. Studies also will look into whether cholesterol-lowering statins can help sufferers of the disease.
According to the NIH, eight to 12 million people in the US may be living with PAD. The disease is caused by blockages in the arteries which deliver blood to the legs, and sufferers have an increased risk of heart attack and stroke.
Classic PAD symptoms include cramping in the leg or hip muscles, numbness or weakness in the leg and burning pain in the foot or toes. However, many people with PAD have no symptoms. When identified at a mild to moderate stage, the disease can be treated with medication.
