Peripheral Artery Disease(PAD) Testing
Peripheral artery disease is a common circulatory problem caused by narrowed arteries which reduce blood flow to the limbs. PAD also can be a strong indicator of more widespread fatty deposits being accumulated in the arteries (atherosclerosis). The condition may also reduce blood flow to an individual’s heart and brain.
Often, PAD can be treated by quitting tobacco, exercising, and eating a healthy diet.
Common Tests Used to Diagnose PAD
- The physical exam which sets out to pinpoint the following PAD indicators: signs of a weak or absent pulse below a narrowed area of the artery, evidence of poor wound healing in the area where blood flow is restricted, and decreased blood pressure in an affected limb.
- Ankle-brachial index (ABI): Comparison of the blood pressure in the ankle with the blood pressure in the arm.
- An ultrasound that evaluates blood flow through blood vessels, and identifies blocked or narrowed arteries.
- Angiography: Injection of dye into blood vessels. This test allows the doctor to view blood flow through the arteries as it occurs.
- Blood tests can be taken to measure cholesterol and triglyceride levels in addition to checking for diabetes.
