Procedure for Detecting Clogged Arteries

A wide variety of tests help physicians and patients determine the extent and location of arterial disease. Early determination and action against clogged arteries can stave off amputation, heart attack or stroke.

  1. Differences

    • Peripheral arterial disease (PAD) designates blockage of arteries in extremities like legs and arms. Coronary arterial disease (CAD) is a blockage or narrowing of arteries leading to the heart. Each requires differing procedures for detection.

    PAD Procedures

    • The ankle/brachial index (ABI) measures the difference between blood pressure in the lower legs and blood pressure in the arms. "The ABI screening helps evaluate the amount of blood flow to the legs and feet, which is decreased in a person with PAD," according to the Cleveland Clinic.

    Other PAD Procedures

    • A pulse volume recording investigates blood volume changes occurring in the legs, while a vascular ultrasound measures blood circulation around an affected artery. An angiography utilizes dye and x-rays to detect blockages; CT scans and MRIs provide images of arteries for study.

    CAD Procedures

    • An electrocardiogram, also referred to as an ECG or EKG, provides an overview of the heart's electrical activity. An echocardiogram uses soundwaves to produce an image of the heart. These tests can detect signs of CAD, says the Mayo Clinic.

    Other CAD Procedures

    • A stress test, either on a treadmill or exercise bike, is a common procedure; sometimes, medication will be used to simulate exercise. A nuclear stress test measures blood flow to the heart, and a coronary catheterization, CT scan or MRI can detect clogged arteries.
