The ABPI test is a popular tool for the non-invasive assessment of Peripheral vascular disease (PVD). Studies have shown the sensitivity of ABPI is 90% with a corresponding 98% specificity for detecting hemodynamically significant ( stenosis of more than 50%) in major leg arteries, defined by angiogram.
Critical limb ischemia is diagnosed by the presence of ischemic rest pain, and an ulcers that will not heal or gangrene due to insufficient blood flow. [3] Insufficient blood flow may be confirmed by ankle-brachial index (ABI), ankle pressure, toe-brachial index (TBI), toe systolic pressure, transcutaneous oxygen measurement (TcpO2 ), or skin perfusion pressure (SPP).
Sudden stabbing chest pain Classic chest pain typically feels like pressure, fullness, or squeezing, and it often gets worse with exertion and then goes away before coming back again later.
Measuring the ankle-brachial index. Diagnosing or identifying peripheral artery disease requires a history of symptoms and a physical exam, followed by confirmatory testing. [20] These tests could include CT scans (Computed Tomographic Angiography), MRA scans (Magnetic Resonance Angiography), or ultrasounds for imaging. [31]
On inspection the clinician looks for signs of: trauma; previous surgery ()muscle wasting/muscle asymmetry; edema (swelling) erythema (redness); ulcers – arterial ulcers tend to be on the borders / sides of the foot, neuropathic ulcers on the plantar surface of the foot, venous ulcers tend on be on the medial aspect of the leg superior to the medial malleolus.

The use of lower leg compression stockings has been found to reduce symptoms and heart rate when standing upright, in patients with postural orthostatic tachycardia syndrome. Usage of compression garments on abdomen and thighs, and a combination of abdominal/thigh and leg covering compression was found to be more effective, with the latter ...
Repeat the test with both legs, testing each leg at least twice for consistency." More than 30 seconds: Indicates excellent balance. Being able to stand on one leg for over 30 seconds generally ...
