- For attack reduction in chronic stable angina, acupuncture bested sham treatment or no acupuncture as adjunctive therapy in this randomized trial.
Why this matters
- Many patients turn to alternative therapies, and randomized controlled trials of such interventions are needed.
- Reductions in attack frequency (magnitude of reduction; 95% CIs):
- Acupuncture targeting the “disease-affected meridian” vs targeting the unaffected meridian: 4.07 (2.43-5.71; P<.001>
- Acupuncture targeting the “disease-affected meridian” vs sham: 5.18 (3.54-6.81; P<.001>
- Acupuncture targeting the “disease-affected meridian” vs waitlist: 5.63 (3.99-7.27; P<.001>
- 398 patients (ages 35-80 years) at 5 centers in China were randomly allocated to 12 sessions of “disease-affected meridian” acupuncture, "unaffected meridian" acupuncture, sham acupuncture, or waitlist groups.
- All had chronic stable angina, with attacks at least twice weekly.
- Outcome: change in attack frequency.
- Funding: Chinese government grants.
- Acupuncture not individualized.
- Small study, short duration.
