Role of micronutrients in congestive heart failure: A systematic review of randomized controlled trials.

ABSTRACT: To assess the effect of micronutrients on health outcomes in patients with heart failure.Only randomized controlled trials testing the effectiveness of different micronutrients either singly or combined versus placebo in heart failure patients were included. We conducted a search in different databases such as Medline from PubMed, Embase and Scopus from Elsevier, and Google Scholar. The keywords used in the search were "Heart Failure" and its cognates, "Micronutrient," "Minerals," and names of individual micronutrients.Out of 3288 titles and abstracts reviewed, only 11 trials comprising 529 individuals were found to be appropriate to be included in the final review. It was found that micronutrients, either single or combined, improved the health outcomes of heart failure patients by improving exercise tolerance, functional capacity, left ventricular function, flow-dependent dilation, and inflammatory milieu, thereby improving the quality of life of health failure patients. Certain micronutrients also normalized endothelial dysfunction.Overall, this systematic review found sufficient evidence to support a large-scale trial on micronutrient supplementation in patients with heart failure.

Project description:Background:Shengmai injection (SMI) is made from purified ginseng, Radix Ophiopogonis, and Schisandra chinensis. It has cardiotonic effects and is clinically used for the adjuvant treatment of chronic heart failure (CHF). However, its efficacy and safety are uncertain. The purpose of this study was to systematically evaluate the existing efficacy and safety evidence in randomized controlled trials (RCTs) that studied SMI for the treatment of CHF. Methods:PubMed, Embase, Cochrane Library, clinicaltrials.gov, CNKI, Wanfang, VIP, and CBM databases were searched up to September 10, 2019. RCTs that compared basic Western medicine treatment with SMI?+?basic Western medicine were included. The Cochrane Collaboration Risk of Bias Tool was used to assess the risk of bias in the RCTs. The meta-analysis used the random effects model; the mean difference (MD) and 95% confidence intervals (CIs) were combined using the inverse variance method, and the Mantel-Haenszel method was used to combine the relative risk (RR) and 95% CIs. Heterogeneity was assessed using I2 and Q tests, and the source of heterogeneity was explored by analyzing three preset subgroup hypotheses. Results:A total of 20 RCTs were included (n?=?1562), with a moderate-to-high risk of bias. The meta-analysis showed that, compared with Western medicine alone, SMI adjuvant therapy significantly improved cardiac function indicators, including left ventricular ejection fraction (MD 6.8%, 95% CI 4.68 to 8.91), stroke volume (MD 9.81?ml, 95% CI 5.67 to 13.96), cardiac output (MD 0.96?L/min, 95% CI 0.66 to 1.25), and cardiac index (MD 0.53?L/min, 95% CI 0.36 to 0.70); heterogeneity was generally high among these outcomes. Compared with the controls, patients receiving SMI adjuvant therapy also had a higher response to treatment (RR 2.89, 95% CI 2.10 to 3.99; I2?=?0%), a greater decrease in brain natriuretic peptide levels (MD -284.66?ng/l, 95% CI -353.73 to -215.59, I2?=?0%), and a greater increase in six-minute walk test performance (MD 70.67?m, 95% CI 22.92 to 118.42; I2?=?84%). Nine studies reported mild adverse events, such as gastrointestinal reactions, and no serious adverse events were reported. Conclusion:Currently, available evidence indicates that SMI, as an adjuvant for basic Western medicine treatment, can improve the cardiac function of patients with CHF with good safety outcomes. Because of the high risk of bias among the included RCTs and the large heterogeneity of partial outcomes, the findings of this study must be verified by high-quality studies with large sample sizes.

Project description:BackgroundHeart failure hospitalization (hHF) with dipeptyl-dipeptidase-4 inhibitors (DPP-4Is) remains at the center stage since the publication of Saxagliptin Assessment of Vascular Outcomes Recorded in Patients with Diabetes Mellitus - Thrombolysis in Myocardial Infarction (SAVOR-TIMI) in 2013 showing significant increase with saxagliptin, compared to placebo. This outcome led to additional label of hHF to both saxagliptin and alogliptin in April 2016 and eventual labelling of hHF to all the four approved DPP-4Is in United States in August 2017, by US Food Drug Administration. To note, neither Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS), nor Cardiovascular and Renal Microvascular Outcome Study with Linagliptin (CARMELINA), showed any signals of hHF with these two agents. These developments have seriously generated an uncertainty among clinicians with regards to hHF effect of DPP-4Is in type 2 diabetic patients with high risk of cardiovascular (CV) disease.Aims and objectivesWe systematically searched the database of PubMed, Embase, Cochrane Central library, ClinicalTrials.gov, and International conference presentation from the inception up to October 25, 2018 using MeSH and specific key words. We retrieved all those studies that explicitly looked for hHF as a prespecified end point and were conducted for ≥52 weeks. Subsequently, we conducted the meta-analysis using comprehensive meta-analysis software Version 3, using different sensitivity analysis to study the effect of DPP-4Is on hHF in both dedicated CV outcome trials as well as randomized controlled trials.ResultsThe meta-analysis of four exclusive dedicated CV outcome trials (N = 43,522) did not find significant increase in hHF with DPP-4 inhibitors (Fixed model Relative Risk [RR] 1.06; 95% Confidence Interval [CI], 0.96-1.17; P = 0.25; I2: 53.95%, tau2: 0.012, P = 0.089). Meta-analysis of all randomized controlled trials that explicitly looked for hHF for ≥52 weeks (N = 48,199) also did not show any significant increase in hHF (fixed model peto odds ratio 1.05; 95% CI 0.95-1.15, P = 0.36; I2: 43.74%, tau2: 0.016, P = 0.10).ConclusionsThis meta-analysis suggests no significant increase in hHF with DPP-4 inhibitors, although a nonsignificant heterogeneity across the trials might limit this observation.
