    Abstract:
    Given that functional abnormalities of the microcirculation are one of the primary abnormalities in cardiovascular disease pathogenesis, various noninvasive clinical tools have been developed recently to assess the microvascular function, particularly at the skin. The common techniques used to assess cutaneous microvascular function in vivo include capillaroscopy, venous occlusion plethysmography, and laser-Doppler instruments (laser-Doppler fluximetry and laser-Doppler imaging). These noninvasive techniques can be used as an early measure of functional abnormalities within the microvascular tree, predominantly in population at high risk for cardiovascular events. This review discusses some underlying application principle of these techniques, including its clinical significance, method reproducibility and limitations.
