Pathological Information on Infrared radiation spectrums at the Neiguan acupoint in patients with coronary atherosclerotic heart disease

BACKGROUND: Infrared spectrum technology has potential and important value of application in diagnosing disease and analyzing pathology, as well as providing references for proper treatment. OBJECTIVE: To analyze the distinctive pathological information in the spectrums of infrared radiation at Neiguan (PC 6) acupoint of patients with coronary atherosclerotic heart disease (CAHD). DESIGN: Case-control study.SETFING: Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. PARTICIPANTS: The study was conducted from April 2003 to April 2005 in patients with CAHD from Out-Patient Clinic in Longhua Hospital (21 males and 29 females, averagely 58.1 years). Forty-seven healthy volunteers were all from advertisement (25 males and 22 females, averagely 50.6 years). All the subjects were voluntary. METHODS: PHE201, a high-sensitive infrared spectrum detective device (Shanghai Institute of Technical Physics of Chinese Academy of Sciences, China) was applied to detect the spectrums of infrared radiation at Neiguan in 50 patients with CAHD and 47 healthy adults were selected as control for comparison. The scanning range was from 1.5μ m to 16μ m,73 detected wavelength spots were scanned at Neiguan of all the subjects, and the scanning spacing was 0.2μ m. MAIN OUTCOME MEASURES: Intensity of infrared radiation at Neiguan between CAHD patients and normal controls at different wavelengths. RESULTS: The intensities of infrared radiation of CAHD patients were significantly different from that of the healthy volunteers at 32 spots of the right Neiguan as well as at 23 spots of the left Neiguan among the 73 detected wavelength spots(P < 0.05-0.001). At 2-2.5μ m wavelength spots that were related to the energy metabolism, the intensities of infrared radiation of CAHD patients were significantly lower than the healthy volunteers (P < 0.05-0.005). Concerning the difference in intensities of infrared radiation between the left and the right Neiguan, the CAHD patients had more wavelength spots than healthy volunteers did (P < 0.001). CONCLUSION: ①Distinctive pathological information exists in the infrared spectrums at Neiguan in CAHD patients. ②CAHD patients have hypo-activities of energy metabolism and hypo-function ofqi and blood in the area of Neiguan.
