ABI/ PVR Testing
The Ankle/Brachial Index, or ABI compares the systolic blood pressure of the ankle to that of the arm (brachial) using regular blood pressure cuffs. These measurements are useful in the diagnosis of patients with peripheral vascular disease (PVD). ABI’s provide an objective baseline to follow the progression of the disease process and evaluate the effectiveness of the treatment plan. Importantly, an abnormal ABI is also correlated with a significantly elevated risk of having a heart attack or stroke, so serves as a marker of overall vascular disease as well. The ABI results are usually combined with Doppler or pulse volume waveform analysis (PVR).
