Dazhu Hongjingtian (Herba Rhodiolae) for unstable angina pectoris: Protocol for a systematic review and meta-analysis.

ABSTRACT: BACKGROUND:Dazhu Hongjingtian (DZHJT), also named Herba Rhodiolae, has been frequently introduced for patients with angina pectoris in China. However, the add-on effect of DZHJT in unstable angina pectoris (UAP) has not been systematically evaluated. The purpose of this protocol is to provide the methods used to assess the efficacy and safety of DZHJT as adjuvant therapy for management of UAP. METHODS:We will extensively search for eligible studies in PubMed, Emase, Cochrane Library, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang, and VIP databases up to October 2018. Only randomized controlled trials comparing DZHJT in combination with Western medicine vs Western medicine alone were selected.The primary outcomes are above 50% reduction in frequency of angina attacks and weekly frequency of angina attacks reduction. The secondary outcomes are the blood rheology parameters (whole-blood viscosity, plasma viscosity, and fibrinogen) and adverse events. We will use RevMan V.5.0 software to perform meta-analysis. RESULTS:The pooled results will provide a high-quality of evidence of DZHJT as adjuvant therapy in patients with UAP. CONCLUSION:This systematic review and meta-analysis will provide up-to-date evidence to evaluate DZHJT as adjuvant therapy in patients with UAP. PROSPERO REGISTRATION NUMBER:PROSPERO CRD42018111885.

Project description:IntroductionPrevious reviews indicate that the effect of acupuncture on stable angina pectoris (SAP) remains controversial. The results of trials published in the past 5?years may possibly change this situation, but an updated systematic review is not available. We therefore designed this study to systematically assess the efficacy and safety of acupuncture for treating SAP.Methods and analysisNine online databases will be searched without language or publication status restrictions from their inception to September 2017. Randomised controlled trials that include patients with stable angina receiving acupuncture therapy versus a control group will be deemed eligible. The selection of studies, data extraction and risk of bias assessment will be carried out by two independent reviewers. Data synthesis will be performed using RevMan V.5.3 software with either a fixed effects model or random effects model, depending on the heterogeneity test. Evidence quality will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation system. The efficacy-effectiveness spectrum for each included trial will be rated using the Rating of Included Trials on the Efficacy-effectiveness Spectrum tool. Outcomes of interest include the improvement of weekly angina attacks and reduction of nitroglycerin medication use after receiving acupuncture treatment, the incidence of cardiovascular events, heart rate variability, pain intensity measured on a visual analogue scale, total workload and exercise duration at peak exercise, safety and adverse events. A meta-analysis will be conducted if no considerable heterogeneity is detected. The results will be presented as risk ratios with 95% CIs for dichotomous data and weighted mean differences or standardised mean differences with 95% CIs for continuous data.Ethics and disseminationThis systematic review will not involve private information from individuals or endanger their rights, and therefore does not necessarily require ethical approval. The results may be published in a peer-reviewed journal or disseminated in relevant conferences.Trial registration numberCRD42015016201.

Project description:Objective: Xueshuantong (lyophilized) for injection (XST) is an effective botanical drug for treating unstable angina pectoris (UAP). However, a meta-analysis of XST combined with conventional treatment (CT) against UAP has not been conducted. Therefore, this study aimed to investigate the effectiveness and safety of XST combined with CT for UAP patients compared to CT alone. Methods: Randomized controlled trials (RCT) of XST in UAP patients were retrieved from the Cochrane Library, PubMed, Web of Science, EMBASE, CNKI, VIP, Wanfang, and Chinese Biological Medicine Database databases. A meta-analysis was performed using Revman 5.4 and Stata 16.0, and the quality of the included literature was evaluated based on the Cochrane risk-of-bias 2.0 (RoB2.0) tool. The aggregate 95% confidence intervals (CIs), mean difference (MD), and relative risk (RR) estimates were calculated. A GRADE assessment was performed using GRADEprofiler 3.6, and trial sequent analysis was performed using TSA 0.9. Results: Thirty-four studies involving 3,518 patients were included in the analysis. The combination of CT with XST improved the comprehensive clinical efficacy (RR = 1.22, 95% CI: 1.18-1.26, p < 0.00001) and ECG improvement (RR = 1.24, 95% CI: 1.18-1.31, p < 0.00001). The frequency of angina attacks was lower (MD = -0.73, 95% CI: -0.92 to -0.55, p < 0.00001), and the duration was shorter (MD = -1.08, 95% CI: -1.44 to -0.72, p < 0.00001) in the group that received CT combined with XST compared to the one without XST. Total cholesterol levels (MD = -1.30, 95% CI: -1.83 to -0.78, p < 0.00001) and triglyceride levels (MD = -0.76, 95% CI: -0.93 to -0.59, p < 0.00001) were lower in patients who received CT in combination with XST than those who received CT alone. CT combined with XST reduced whole blood viscosity (MD = -0.72, 95% CI = -0.99 to -0.44, p < 0.00001) and plasma viscosity (MD = -0.24, 95% CI: -0.46 to -0.03, p = 0.03). There was no statistically significant difference in the incidence of cardiovascular events or adverse events among patients treated with the combination of XST and CT compared to CT alone. The GRADE assessment indicated that the composite quality of the evidence was low. The trial sequent analysis showed an adequate sample size and stable findings for the clinical efficacy of CT combined with XST for unstable angina. Conclusion: The present systematic review and meta-analysis conditionally indicate that XST combined with CT improved the clinical outcomes of patients with unstable angina more than CT alone with a better safety profile. However, the results need further validation due to limitations in the quality of the included studies.

Project description:Objective: Dazhu hongjingtian [DZHJT, Rhodiola wallichiana var. cholaensis (Praeger) S.H. Fu] preparation as an add-on therapy has been applied to the treatment of angina pectoris. We aimed to evaluate the efficacy and safety of DZHJT as adjuvant therapy for the treatment of unstable angina pectoris (UAP). Methods: An extensive literature search was conducted on PubMed, Emase, Cochrane Library, Wanfang, CNKI, and VIP databases from inception to January 2019. Randomized controlled trials (RCTs) comparing DZHJT in combination with Western medicine with Western medicine alone were included. Two authors independently performed the literature search, data extraction and risk of bias assessment of included studies, and conducted the statistical analysis. Results: A total of 18 RCTs involving 1,679 patients were included in the meta-analysis. Adjuvant treatment with DZHJT significantly decreased ?80% reduction in the frequency of angina attacks [risk ratio (RR) 1.57; 95% CI 1.36-1.81], weekly frequency of angina attacks [mean difference (MD) -1.03 times; 95% confidence interval (CI) -1.51 to -0.55], marked improved abnormal electrocardiogram (RR 1.46; 95% CI 1.23-1.74). In addition, DZHJT significantly reduced the whole-blood viscosity (MD -0.70 mPa.s; 95% CI -0.84 to -0.55), plasma viscosity (MD -0.28 mPa.s; 95% CI -0.38 to -0.19), serum level of fibrinogen (MD -0.67 g/L; 95% CI -0.79 to -0.54), thromboxanes B2 (MD -14.01 ng/L; 95% CI -20.86 to -7.15), and C-reactive protein (MD -1.48 mg/L; 95% CI -2.72 to -0.25). No significant differences in headache/dizziness (RR 0.72; 95% CI 0.31-1.67) were observed between two groups. Conclusion: Adjuvant treatment with DZHJT has an add-on effect in reducing angina pectoris attacks in patients with UAP. The beneficial effect may be correlated with regulating whole-blood viscosity, plasma viscosity, fibrinogen, thromboxanes B2, and CRP level. However, future well-designed prospective, randomized, double-blind placebo-controlled trials with large sample sizes are required to evaluate the evidence.
