Ivabradine for the Therapy of Chronic Stable Angina Pectoris: a Systematic Review and Meta-Analysis.

ABSTRACT: BACKGROUND AND OBJECTIVES:Coronary artery disease (CAD) is the number one cause of death worldwide. The If channel inhibitor ivabradine serves as second line medication for the CAD leading symptom angina pectoris. This systematic review and meta-analysis assess the existing evidence of ivabradine in angina pectoris. METHODS:We systematically searched MEDLINE, Embase, CENTRAL, and Web of Science (September 2019) for randomized controlled trials (RCTs) that compared ivabradine versus placebo, standard therapy (ST) or other anti-anginal drugs. Two review authors independently assessed trials for inclusion and performed data extraction. We completed a 'risk of bias' assessment for all studies and assessed quality of the trial evidence using the Grading of Recommendations Assessment, Development and Evaluation methodology. We meta-analysed data were applicable and calculated mean differences (MDs) and risk ratios using a random-effects model. RESULTS:A total of 11 RCTs (n=16,039) were included. Compared to placebo/ST, we found significant effects on the frequency of hospitalisation in a small cohort (n=90; hazard ratio [HR], 0.19; 95% confidence interval [CI], 0.04, -0.92; p=0.04), but no effects on cardiovascular mortality (n=19,102; HR, 1.10; 95% CI, 0.94, 1.28; p=0.25) or the frequency of angina pectoris episodes (n=167; weighted MD, -1.06; 95% CI, -2.74, -0.61; p=0.21). CONCLUSIONS:The present work makes an important contribution to optimal patient care in angina pectoris by complementing the current European Society of Cardiology guideline-recommending class IIa with evidence level B-decisively with 8 further studies.

Project description:IntroductionBeta-blockers are recommended by the European Society of Cardiology as first-line antianginal therapy for reducing heart rate (HR) and symptoms in patients with chronic coronary syndrome, despite a lack of data showing superiority to other antianginal agents. Most patients with angina pectoris require combination therapy to manage symptoms, with a second-line agent chosen to manage the predominant cardiovascular problem. Ivabradine, a selective sinus node If channel inhibitor shown to reduce HR and protect against anginal symptoms, has previously demonstrated noninferior anti-ischaemic and antianginal efficacy to beta-blockers.MethodsThis systematic review and meta-analysis assessed the efficacy and safety of ivabradine in patients with stable angina pectoris who remained symptomatic despite receiving beta-blockers. Keyword searches of PubMed, The Cochrane Central Library Register, ClinicalTrials.gov, The World Health Organization International Clinical Trials Registry Platform (ICTRP) and Google Scholar identified studies comparing ivabradine plus beta-blockers with placebo or other first- or second-line antianginal agents in patients with stable angina pectoris. No date limits or language restrictions were applied. Outcomes were evaluated after 1 and 4 months of treatment, including changes in HR, angina attacks, use of short-acting nitrates, quality of life and safety. Risk of bias was evaluated on the basis of recommendations of the Cochrane Handbook for Systematic Reviews of Interventions.ResultsSeven relevant studies were identified (N = 6821). Ivabradine plus a beta-blocker consistently reduced HR, anginal symptoms and short-acting nitrate consumption within 1 month of initiating therapy, with continued reductions for up to 4 months. Furthermore, ivabradine plus beta-blocker therapy was well tolerated, with bradycardia rarely reported (0.1% of patients overall). This study is limited by the inclusion of only two randomised studies, which may lead to result interpretation bias.ConclusionsIvabradine may be valuable for tailoring early antianginal treatment when used in combination with beta-blockers for chronic stable angina inadequately controlled by beta-blockers.

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:BackgroundChronic stable angina (CSA) resulted in a considerable burden for both individuals and the society. In this study we aimed to critically evaluate the effectiveness and safety of Compound salvia pellet compared with nitrates in the treatment of Chronic Stable Angina (CSA) pectoris, and to provide more credible evidence for clinical practice.MethodsA comprehensive and exhaustive search strategy was formulated to identify potential RCTs of compound salvia pellet for CSA in international and Chinese databases from their inception to July 4th, 2018. We also searched the bibliographies of relevant studies. Two reviewers independently assessed the quality of included trials by using Cochrane Risk of Bias Tool.ResultsThe literature search yielded 1849 citations and 51 RCTs (n = 4732) were included for meta-analysis after titles, abstracts and full text selection according to eligibility criteria. The pooled results suggested that compound salvia pellet was much more effective than nitrates in the improvement of angina symptoms (therapy = 4 weeks, RR = 1.23, 95%CI = [1.17, 1.30], P < .001, I = 0%; therapy = 4 weeks, RR = 1.13, 95%CI = [1.08, 1.17], P < .001, I = 45.6%), and ECG test (therapy = 4 weeks, RR = 1.24, 95%CI [1.14, 1.35], P < .001, I = 51.5%; and therapy > 4 weeks, RR = 1.30, 95%CI[1.20, 1.42], P < .001, I = 36.4%) in CSA. Compared with nitrates, the percentage of patients with adverse events significantly decreased when prescribed with compound salvia pellet (3.2% vs 17.0%).ConclusionCompound salvia pellet might be more effective on the improvement of angina symptoms, ECG test and with few adverse events compared with nitrates. While there are some limitations in this study, which may weaken the results, we believe the findings could provide useful information for stakeholders concerned with outcomes in patients with CSA. More rigorous RCTs with high quality are needed to confirm these findings.
