Acupuncture in Arterial Hypertension: Evaluation of its Efficacy with Both Office and Ambulatory Blood Pressure Measurements.

INTRODUCTION

A possible alternative to pharmacological antihypertensive therapies in grade 1 low risk hypertensive patients or in those experienced drugs adverse effects could be acupuncture.

AIM

we focused on its possible effects on BP both as Office BP (OBP) and as Ambulatory BP Monitoring (ABPM) evaluating it before starting a 6 weeks twice weekly (total 12 session) acupuncture cycle and after 2 months from its completion.

METHODS

in this prospective study we treated with acupuncture 45 patients: 24 of them presents high-normal BP values and low cardiovascular risk while 21 patients were on anti-hypertensive drug with slightly uncontrolled BP values (from 140 to 145 mmHg for Systolic BP-SBP-and/or from 90 to 95 mmHg for Diastolic BP-DBP).

RESULTS

regarding SBP, a significant reduction have been observed for office values (from 134.2 ± 15.7 to 125.1 ± 12.2, p = 0.03), and for ABPM 24 h (from 131.1 ± 10.7 to 126.0 ± 10.1, p = 0.01) and day-time values (from 134.7 ± 10.5 to 127.1 ± 18.4, p = 0.02). For DBP, only ABPM 24 h and day-time values showed significant changes (from 85.3 ± 9.1 to 82.1 ± 7.5, p = 0.03; and from 88.5 ± 9.3 to 85.7 ± 7.8, p = 0.02). Within session SBP decrease was - 5.8 mmHg (-3.75%) during the first session while it falls to - 2.1 mmHg (- 1.25%) and stands firmly under 2 mmHg for all the next session. At the last session SBP reduction was - 1.9 mmHg (- 1.6%).

CONCLUSIONS

we found a significant reduction in office, 24 h and day-time ABPM SBP determined by a 6-weeks twice weekly acupuncture cycle that lasts at least for the first two months after its completion.
