Objective:To obtain the infrared thermogram characteristics of patients with coronary heart disease of phlegm-stasis intertwined pattern.Methods:In the First Affiliated Hospital of Hunan University of Chinese Medicine,Sichuan Provincial Integrated Hospital of Traditional Chinese and Western Medicine,health management Center of Dongzhimen Hospital of Beijing University of Chinese Medicine,and TCM outpatient center,a total of 277 patients with stable phlegm-stasis intertwined pattern of coronary heart disease were screened,and basic personal information,related clinical auxiliary examination results,infrared thermograms were collected.Infrared thermogram software analysis platform was used to extract temperature data of body surface areas,meridians and acupoints of sample population,to analyze and summarize the infrared thermogram characteristics of patients with coronary heart disease of phlegm-stasis intertwined pattern.Results:The left and right sides of the front and back images of patients were asymmetrical,the local color of the infrared thermogram was uneven,and the color between the high temperature area and the low temperature area was abrupt(specific areas that did not meet the symmetry,uniformity and gradual change should be described specifically for specific individuals).Cool deviations were observed in the middle-Jiao,left chest,right chest,Daling(PC7),Shenmen(HT7).The temperature difference(△T)of the left chest was smaller than that of the right chest,and the discrepancy was most pronounced in winter.The △T of the Conception Vessel was lower than that of the Governor Vessel,with the surface temperature of the frontal torso being higher than that of the dorsal torso.The△ T difference between the left and right Neiguan(PC6)reached the maximum in summer,whereas the △T difference between the left and right Xinshu(BL15)attained its peak in winter.Conclusion:The symmetry,uniformity and gradual degeneration of infrared thermogram are abnormal in patients with coronary heart disease of phlegm-stasis intertwined pattern.The larger △ T between the left and right chest,the left and right Xinshu and the left and right Neiguan,the more insufficient the cardiac blood supply.This can serve as a specific index for evaluating cardiac function status,and has certain clinical value in assessing cardiac blood supply capacity.By conducting a multidimensional analysis of infrared thermographic characteristics in patients with coronary heart disease of presenting phlegm-stasis intertwined pattern,infrared thermal imaging technology can be utilized to assess the severity of myocardial ischemia and evaluate therapeutic outcomes in such patients.This approach facilitates the digitization,visualization and objectification of traditional Chinese medicine syndrome differentiation,thereby holding important clinical application value.
