Résumé
Objective To explore the association between precordial skin temperature and coronary heart disease and effect of moxibustion at Neiguan (PC 6) on precordial skin temperature in patients with coronary heart disease. Method Thirty healthy volunteers (control group) and thirty patients with coronary heart disease (treatment group) received infrared thermal imaging examination on region A (precordial region) and region B on chest. Afterwards, all subjects were given moxibustion at Neiguan (PC 6) and then received infrared thermal imaging examination again. The temperatures of before and after moxibustion were compared. Result In the treatment group, there was a significant difference in comparing the average temperature in region A and B before moxibustion (P<0.05), and the difference was statistically significant after moxibustion (P<0.05). After moxibustion, there was a significant difference in comparing the average temperature in region A between the two groups (P<0.05). Conclusion To some extent, the precordial skin temperature reflects the blood supply condition of coronary artery. Moxibustion at Neiguan (PC 6) can change the temperature and improve the coronary blood supply.
