艾灸内关穴对冠心病患者心前区皮温的影响

Effect of Moxibustion at Neiguan(PC 6) on Precordial Skin Temperaturei in Patients with Coronary Heart Disease

目的探讨心前区皮温与冠心病的发病关系以及艾灸内关穴对冠心病患者心前区皮温的影响。方法对30例健康志愿者(对照组)和30例冠心病患者(治疗组)进行常规胸部A区(心前区)和B区红外线热成像检查,检查后所有受试者给予艾灸内关穴,再对艾灸前后热像图的温度进行对比分析。结果治疗组治疗前A区平均温度与同组B区比较,差异具有统计学意义(P<0.05)。治疗组治疗后A区平均温度与同组B区比较,差异具有统计学意义(P<0.05)。治疗组治疗后A区平均温度与对照组比较,差异具有统计学意义(P<0.05)。结论胸部A区(心前区)皮温在一定程度上反应了冠脉供血状态。艾灸内关穴可以改变胸部A区(心前区)的皮温,具有改善心肌供血的作用。

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.
