Location of 4 somatic measurement sites.

BackgroundAlthough the relationship between viscera and somato remains unclear, a deeper comprehension of the relationship will maximize the diagnostic and therapeutic benefits. Therefore, this study was conducted to explore the specificity of visceral-somatic associations in the pathological state of chronic stable angina pectoris (CSAP).Methods40 individuals with CSAP participated in the study, while 40 individuals in the healthy control group were age-matched healthy individuals. Four distinct somatic locations dispersed along the heart and lung meridians were subjected to laser doppler flowmetry, infrared thermography, and functional near-infrared spectroscopy in order to assess (1) perfusion unit (PU), (2) temperature, and (3) regional oxygen saturation (rSO2). These three outcomes represented the somatic sites’ microcirculatory, thermal, and metabolic properties.ResultsRegarding the microcirculatory characteristics, PU at the somatic sites of the heart meridian (Shenmen(HT7)/Shaohai(HT3)) in the CSAP group substantially increased (P P 2 of the somatic site of the heart meridian (Shaohai (HT3)) in the CSAP group decreased significantly (P ConclusionsSpecific somatic sites in the heart meridian typically exhibit more significant changes in their microcirculatory, thermal, and metabolic characteristics than those in the lung meridian, thereby supporting the relative specificity for the visceral-somatic association in the disease state of CSAP.
