A Randomized Controlled Trial on the Efficacy of Xinnaoning Capsule in the Treatment of CSAP Complicated With Qi Stagnation and Blood Stasis Syndrome.

Objective: This study was designed to explore the efficacy and safety of Xinnaoning Capsule (XNNC) in the treatment of patients with chronic stable angina pectoris (CSAP) complicated with Qi stagnation and blood stasis syndrome. Methods: A total of 240 patients with CSAP complicated with Qi stagnation and blood stasis syndrome who met the inclusion criteria were enrolled from 8 medical centers across China. The trial treatment lasted 14 weeks, including a 2-week lead-in period and a 12-week double-blind treatment period. Patients in the experimental group were treated with XNNC, while patients in the control group were treated with placebos. Thereafter, examinations were conducted on the efficacy of angina pectoris before and after treatment and the relief of symptoms, followed by the recording of grading changes in angina severity, changes in the number of angina pectoris, and the amount of taken nitroglycerin. Finally, adverse events were assessed. Results: Compared with the control group, the total score and the effective rate of angina pectoris were significantly increased in the experimental group, accompanied by the statistically significant improvement in the severity of angina pectoris (all p < 0.05). Furthermore, there was no statistically significant difference in the adverse events and serious adverse events between the experimental group and the control group (p = 1.0000) before and after treatment. Conclusion: XNNC is a safe and effective medicine for patients with CSAP complicated with Qi stagnation and blood stasis syndrome.

Acupuncture for treating chronic stable angina pectoris associated anxiety and depression: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Despite that acupuncture is effective in treating anxiety, depression and chronic stable angina pectoris (CSAP), it remains unclear whether acupuncture can treat CSAP, anxiety and depression simultaneously. This systematic review and meta-analysis aimed to investigate the efficacy of acupuncture on CSAP-associated anxiety and depression. METHODS: Eight electronic databases were searched to identify eligible randomized controlled trials (RCTs) or controlled clinical trials (i.e. "acupuncture alone or combined with standard care" versus " sham acupuncture alone, sham acupuncture with standard care, or standard care alone") from their inception to January 2021, which included PubMed, Embase, Web of Science, the Cochrane Library, CBM, CNKI, VIP and Wanfang Database. Data were extracted and meta analyses were performed using the RevMan 5.3. Risk of bias (ROB) 2.0 was used for methodological quality assessment. GRADEprofiler 3.2.2 was used to rate the quality of evidence. RESULTS: Seven trials involving 893 subjects were included. Meta-analysis results showed that acupuncture combined with standard care was more effective in relieving anxiety and depression, reducing angina attack frequency, and angina pain intensity than sham acupuncture with standard care and standard care alone. In addition, the effect remained until 16 weeks after acupuncture. The safety of acupuncture for CSAP-associated anxiety and depression was also high. Nonetheless, the quality of evidence ranged from low to moderate. CONCLUSION: Acupuncture may be used as an adjunctive therapy to treat CSAP-associated anxiety and depression. However, more high-quality RCTs are required to confirm our findings.

Effectiveness and Safety of Acupoint Application of Guan Xin Su He Pill () for Patients with Chronic Stable Angina Pectoris: A Multi-Center, Randomized Controlled Trial.

OBJECTIVE: To assess the clinical effectiveness of acupoint application (AP) of Guan Xin Su He Pill (, GXSHP) for patients with chronic stable angina pectoris (CSAP). METHODS: This study was carried out in 3 local hospitals in Chengdu, China. After baseline evaluation, eligible patients were randomly assigned to the placebo application for acupoints (PAA) group or the herbal application for acupoints (HAA) group. Patients in the HAA group underwent AP with herbal powder, which was mainly GXSHP, and patients in the PAA group underwent AP with sham drugs. For each treatment session, unilateral acupoints including Neiguan (PC 6), Danzhong (RN 17), Xinshu (BL 15) and Jueyinshu (BL 14), were stimulated for both groups. AP was performed 3 times a week with a 2-day interval for 4 weeks. The primary outcome was the frequency of angina pectoris attacks per week, while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale (VAS), dose of rescue oral drugs (nitroglycerin), scores on the Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale scores (SAS) and Self-Rating Depression Scale scores (SDS). Clinical outcomes were measured at week 0, 4 and 8. The safety of AP of GXSHP treatment for CSAP were assessed. RESULTS: A total of 121 patients were enrolled. Baseline characteristics were comparable across the 2 groups. After treatment, the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81 (P<0.05). While, for PAA group, the angina frequency was not significantly improved (baseline 10.55; post-treatment 11.05). The HAA group had significantly fewer angina attacks than the PAA group (P<0.05). Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02 (P<0.05). While, for PAA group, the VAS was significantly increased (baseline 3.62; post-treatment 3.96; P<0.05). Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs, SAS, SDS and SAQ scores (P<0.05). The adverse events were also reported. CONCLUSION: AP of GXSHP is a safe and effective treatment for CSAP patients (Registration No. NCT02029118).

Acupuncture for chronic stable angina pectoris based on the theory of Meridian-Viscera Association: study protocol for a multicenter randomized controlled trial.

BACKGROUND: Acupuncture has long been used to treat chronic stable angina pectoris (CSAP), but the acupuncture prescription for CSAP varies. This trial will compare the therapeutic effects between the acupoints on the Heart Meridian and the acupoints on the Lung Meridian for treating CSAP, so as to provide a better prescription for acupuncture treatment of CSAP. METHODS: This is a multicenter randomized controlled trial. A total of 148 CSAP patients will be randomly allocated into two groups through central randomization in a 1:1 ratio. This trial will include a 2-week screening period, a 4-week treatment period, and a 4-week follow-up period. The primary outcome is the frequency of angina attacks from baseline to 4 weeks after inclusion. Secondary outcomes include the frequency of angina attacks from baseline to 4 weeks after acupuncture treatment, the pain intensity of angina, total ischemia burden, heart rate variability, QT dispersion, the score of Seattle Angina Questionnaire, and the score of Short-Form of McGill Pain Questionnaire. These outcome measures will be evaluated at baseline, at the end of acupuncture treatment, and at the end of follow-up. DISCUSSION: We hypothesize that the effectiveness of puncturing at acupoints on the Heart Meridian will not be the same as those on the Lung Meridian. The results will provide further evidence of Meridian-Viscera Association theory and references for acupoints selection in the clinical practice.
