Peripheral Artery Disease
Risk Factors for Peripheral Artery Disease
- High blood pressure
- History of smoking
- High cholesterol (high LDL and low HDL)
- High-fat diet
- Being overweight
Treatment for Minor PAD
- Eating a healthy diet to control weight and lower cholesterol.
- Quitting smoking
- Exercising regularly.
- Taking medication to control symptoms and lower cholesterol and blood pressure
Imaging tests, such as the Doppler/Duplex ultrasound and X-ray exam, may be used to diagnose PAD.
The Doppler/Duplex ultrasound
This test detects and measures blood flow and blood pressure behind the knees and at the ankles. Patients with PAD in the legs have a lower blood pressure in the ankles than in the arms. This ankle pressure is called Ankle Brachial Index or ABI. If your Doppler/Duplex ultrasound shows a decrease in pressure in your ABI, your doctor might order a CT scan (also called a CAT scan) .
This exam uses a computer or scanner to help identify where your blockages are in the blood vessels in your legs. A scan called Magnetic Resonance Imaging (MRI) may also be performed to identify where blockages are in your body.
