Researchers from the Beijing University of Traditional Chinese Medicine suggest that electro-acupuncture can enhance blood flow and skin temperature of patients with myocardial ischemia.
According to the study published in Traditional Chinese Medicine, researchers studied the effects of electro-acupuncture on blood flow and skin temperature of the patients. Electro-acupuncture is similar to traditional acupuncture; needles are inserted at particular points on the body where a connected device generates continuous electric pulses using small clips.
In the study, mouse models received electro-acupuncture at the left Neiguan (Pericardium 6) for 20 minutes for three days. Researchers measured the mice’s skin blood flow and temperature using laser speckle contrast imaging and infrared thermal image instruments. They also measured mRNA levels and protein levels of alpha1-adrenoreceptor and beta2-adrenoreceptor (α1-AR and β2-AR) that play help to regulate the skin temperature and blood flow in closing the link to the sympathetic nerve. The serum levels of cardiac troponin T (cTnT) and electrocardiogram were also observed to determine the condition of the myocardium.
Results of the study showed decrease in the levels of α1-AR and increase in the level of β2-AR in models with acute myocardial ischemia. Researchers concluded that low-frequency or high-frequency electro-acupuncture could enhance the skin temperature as well as blood flow in acute myocardial ischemia.
