Effects of electroacupuncture in acute myocardial ischemia patients

A study published in the Journal of Traditional Chinese Medicine looked at the effect of electroacupuncture in acute myocardial ischemia patients.

  • The researchers of the study examined the impact of electroacupuncture of acupoints Neiguan (PC 6) and Tianquan (PC 2) on the skin temperature, blood perfusion, and alpha1- and beta2- adrenoceptor protein (?1-AR and ?2-AR) and mRNA levels in rats with acute myocardial ischemia.
  • They prepared the rat model by closing up the left anterior descending coronary artery.
  • In conducting the study, the researchers randomly assigned thirty male adult rats into five groups – control group, placebo operation group, model group, the model group treated with electroacupuncture at low frequency, and the model group treated with electroacupuncture at high frequency.
  • The treatment groups received electroacupuncture at the left Neiguan for 20 minutes each day for three days.
  • Then, the researchers measured skin blood perfusion and temperature in Neiguan and Tianquan in all groups with the use of laser speckle contrast imaging and infrared thermal image instrument.
  • Results revealed that both low- and high-frequency electroacupuncture could enhance the skin temperature and blood perfusion.
  • The effect can be promoted by reducing the level of ?1-AR and increasing the level of ?2-AR of the Neiguan and Tianquan in the rat with acute myocardial ischemia.

In conclusion, the findings of the study indicate that low- or high-frequency electroacupuncture can enhance the skin temperature as well as blood flow in acute myocardial ischemia.
