Results: After 8 weeks, 33 patients treated with EA at PC 5-6+ST 36-37 had decreased peak and average SBP and DBP, compared with 32 patients treated with EA at LI 6-7+GB 37-39 control acupoints. Changes in blood pressures significantly differed between the two patient groups. In 14 patients, a long-lasting blood pressure–lowering acupuncture effect was observed for an additional 4 weeks of EA at PC 5-6+ST 36-37. After treatment, the plasma concentration of norepinephrine, which was initially elevated, was decreased by 41%; likewise, renin was decreased by 67% and aldosterone by 22%.
Conclusions: EA at select acupoints reduces blood pressure. Sympathetic and renin-aldosterone systems were likely related to the long-lasting EA actions.
UCI researchers have found that electroacupuncture – a form of acupuncture that employs low-intensity electrical stimulation – can reduce high blood pressure in hypertensive patients for up to six weeks. Chris Nugent / UCI
