Blood Flow Is Key To Early Diagnosis And Treatment For People

Detection and treatment
Pharmacology and Therapeutics

The study find that the 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 journal 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).

The detection and treatment

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 note sex and ethnic differences in how critical limb ischemia is diagnose; 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.

Blood flow is the flow of blood in the cardiovascular system. It can be calculated by dividing the vascular resistance into the pressure gradient. Black and Hispanic patients with critical limb ischemia are more likely to have diabetes and chronic kidney disease and are more likely to develop gangrene. White patients are more likely to have ulcers and pain in their legs while at rest.

Critical limb ischemia

Black patients are also 78% more likely to receive lower extremity amputation for critical limb ischemia compared to their white peers, even after adjustment for socioeconomic status; access to facilities with revascularization services and other factors. Critical limb ischemia is the most severe form of peripheral artery disease (PAD); which affects an estimated 12 million Americans. It occurs when the arteries leading to the legs become narrowed or blocked. The condition can lead to gangrene; wounds that don’t heal and amputations if blood flow is not return to the limbs.

Despite the high prevalence of critical limb ischemia, strategies to assess blood flow remain limited. New technologies offer potential opportunities to improve the precision and quality of criticail limb ischemia management, with the goal of earlier detection and treatment to reduce amputations and disability as well as improving the quality of life for patients. Chronic kidney disease (CKD); also known as chronic renal disease, is a progressive loss of renal function over a period of months or years.

The symptoms of worsening kidney function are unspecific, and might include feeling generally unwell and experiencing a reduced appetite. Often, chronic kidney disease is diagnose as a result of screening of people know to be at risk of kidney problems, such as those with high blood pressure or diabetes and those with a blood relative with chronic kidney disease.
