AbstractBackgroundThe prevalence of essential hypertension contributed significantly to morbidity and mortality rates. Acupuncture‐related therapies were commonly employed in hypertension treatment. Nevertheless, a lack of conclusive evidence left uncertainties regarding the optimal strategies for managing hypertensive populations.ObjectivesConduct a comprehensive systematic review to evaluate the existing clinical evidence about the effectiveness of acupuncture and moxibustion‐related therapies in managing hypertension, by employing network meta‐analysis techniques.MethodsA comprehensive electronic search was conducted across n of databases. This search covered studies available up to October 2022. Randomized controlled trials assessing acupuncture and moxibustion‐related therapies in managing hypertension based on traditional Chinese medicine were screened. Primary outcome measures included the antihypertensive effectiveness rate, variations in blood pressure and the incorporation of Traditional Chinese Medicine (TCM) syndrome manifestations. The review follows the guidelines outlined in the PRISMA statement.ResultsWe identified a total of 24 trials with 1867 patients, which evaluated the efficacy of various acupuncture‐related therapies for hypertension management. Network meta‐analysis showed that moxibustion and auricular point sticking combined with medication therapy had the best effect in terms of antihypertensive effective rate (medication + moxibustion + auricular pressure vs. medication = 1.29 [1.09, 1.54]; sucra = 85.9, p < .05) and hypertension symptom improvement (medication + moxibustion + auricular pressure vs. medication = −1.55 [−2.98, −0.13]; sucra = 96.1, p < .05). Acupuncture combined with moxibustion combined with medication therapy had the best effect in reducing systolic pressure (medication + moxibustion + acupuncture vs. medication = −8.50 [−10.19, −6.80]; sucra = 100, p < .05) and diastolic blood pressure (medication + moxibustion + acupuncture versus medication = −4.72 [−6.71, −2.72]; sucra = 99.71, p < 0.05).ConclusionsNetwork meta‐analysis suggested that the combined use of moxibustion and auricular point application in conjunction with drug therapy showed the highest likelihood of being the most effective treatment in terms of antihypertensive efficiency rates and improvement in hypertension symptoms. Furthermore, the combination of acupuncture and moxibustion alongside drug treatment emerged as the most promising approach for reducing systolic blood pressure and diastolic blood pressure. Limited by the methodological quality and quantity of the included studies, the results need to be interpreted with caution. It is necessary to conduct more high‐quality randomized controlled trials of acupuncture‐related therapies for the adjuvant treatment of hypertension in the future.Implications for practiceClinicians can use acupuncture‐related therapies to inform their treatment decisions and potentially incorporate acupuncture‐related therapies into their hypertension management protocols.
