Evaluating blood flow is key to early diagnosis and treatment for people with critical limb ischemia

Non-invasive techniques and devices for assessing blood flow and other diagnostic considerations for people with critical limb ischemia are addressed in a new scientific statement from the American Heart Association, published in the Association’s flagship journalĀ Circulation.

The statement provides perspective on the strengths and limitations of current imaging techniques, including the ankle-brachial index, toe brachial index, toe systolic pressure, transcutaneous oximetry (TcPO2) and skin perfusion pressure (SPP). It also examines tools such as the laser Doppler, speckle imaging devices and others, as well as identifying opportunities for technology improvement and reducing disparities in detection and treatment.

The authors noted sex and ethnic differences in how critical limb ischemia is diagnosed, coexisting conditions and disparities in treatment. Women are more likely to experience emergency hospitalization, have differences in blood flow, and higher disability and death rates.
