Diffuse Optical Spectroscopy Measure Microvascular Changes in Metabolic Syndrome and Diabetes Mellitus in Order to Assess Cardiovascular Disease Risk.
Metabolic Syndrome is a highly prevalent condition that is comprised of several major
clustering factors that increase the risk for developing cardiovascular disease. Diffuse
Optical Spectroscopy is a non-invasively measure can show changes in the microvasculature of
human. Diffuse Optical Spectroscopy measures the optical absorption and scattering
properties of near-infrared light in tissues such as muscle in order to quantify the
absolute concentration of oxygenated and deoxygenated hemoglobin, water, and lipids. It
provides quantitative and functional information on the microvasculature related to tissue
perfusion, metabolic changes, and indicators of tissue damage.

The researchers can use Diffuse Optical Spectroscopy to monitor changes in the
microvasculature of patients with Metabolic Syndrome and diabetic mellitus, and patients
with Diabetic Peripheral and Autonomic Neuropathy, versus non-diseased and predisposed
subjects by evaluating the changes in oxygen metabolism. The Diffuse Optical Spectroscopy
measure the changes in the concentration and oxygen saturation of hemoglobin in the
microvasculature under stress, for example, during exercise and in response to changes in
breathing habits. The sensitivity of Diffuse Optical Spectroscopy to tissue hemodynamics
provides an impressive arena of useful clinical applications..
