Project description:Sacubitril-valsartan has been shown to have superior effects over angiotensin-converting enzyme inhibitors and angiotensin receptor blockers in patients with heart failure (HF) and hypertension. The efficacy and safety of sacubitril-valsartan in patients with HF are controversial. We performed a meta-analysis of randomized controlled trials to assess and compare the effect and adverse events of sacubitril-valsartan, valsartan, and enalapril in patients with HF. We conducted a systematic search using PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov. Randomized controlled trials involving the use of sacubitril-valsartan in patients with HF were included. We assessed the pooled odds ratio (OR) of all-cause mortality, cardiovascular mortality, and hospitalization for HF in fixed-effects models and the pooled risk ratio (RR) of symptomatic hypotension, worsening renal function, and hyperkalaemia in fixed-effects models. Of the 315 identified records, six studies involving 14 959 patients were eligible for inclusion. Sacubitril-valsartan reduced the endpoints of all-cause mortality and cardiovascular mortality in patients with HF with reduced ejection fraction (HFrEF) in three trials with pooled ORs of 0.83 (P = 0.0006) and 0.78 (P < 0.0001), respectively. Regarding the composite outcome of hospitalization for HF in five trials, the pooled OR was 0.79 (P < 0.00001). Compared with enalapril or valsartan, sacubitril-valsartan was associated with a high risk of symptomatic hypotension (RR 1.47, P < 0.00001), low risk of worsening renal function (RR 0.81, P = 0.005), and low rate of serious hyperkalaemia (≥6.0 mmol/L) (RR 0.76, P = 0.0007) in all six trials. Compared with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, sacubitril-valsartan significantly decreased the risk of death from all causes or cardiovascular causes in HFrEF and hospitalization for HF in both patients with HFrEF and HF with preserved ejection fraction. Sacubitril-valsartan reduced the risk of renal dysfunction and serious hyperkalaemia but was associated with more symptomatic hypotension.

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:Background: The effect of testosterone supplementation in patients with chronic heart failure (CHF) remains uncertain. Methods: A meta-analysis of randomized controlled trials (RCTs) was performed. RCTs that evaluate the chronic effect of testosterone supplementation on exercise capacity and cardiac function in CHF were identified via searching of PubMed, Embase, and the Cochrane's Library databases. Heterogeneity was evaluated by the Cochrane's Q test and I 2 statistics. A fixed-effect model was used if the heterogeneity was not significant (I 2 < 50%); otherwise, a random-effect model was applied. Results: Eight studies including 170 patients in the testosterone supplementation group and 162 in the control group were included. Overall, testosterone supplementation was not associated with an improved exercise capacity (walking test: standardized mean difference [SMD] = 0.36, p = 0.07). Sensitivity analyses limited to male patients showed similar results (SMD = 0.21, p = 0.15), and subgroup analyses also showed similar results in male HF patients with baseline total testosterone (TT) ? or < 10 nmol/L. However, patients with TT at endpoint ? 25 nmol/L was associated with improved exercise capacity (SMD = 1.12, p = 0.02), but not for those with TT at endpoint < 25 nmol/L (SMD = 0.24, p = 0.12). In addition, VO2max (weight mean difference [WMD] = 0.85, p = 0.43), the functional classification (the New York Heart Association classification: WMD = -0.08, p = 0.16) and quality of life (Minnesota Living with Heart Failure [MLHF] questionnaire: WMD = -6.03, p = 0.12) were not significantly affected. Moreover, testosterone supplementation did not significantly affect left ventricular ejection fraction (WMD: -1.52%, p = 0.37), serum B-type natriuretic peptide (SMD: -0.19, p = 0.23), or a composite outcome of death or HF hospitalization (risk ratio [RR]: 1.02, p = 0.96). Although testosterone supplementation increased systolic blood pressure (BP) in CHF patients (WMD: 5.68 mmHg, p < 0.001), diastolic BP or heart rate was not significantly changed as compared to control. Conclusions: Testosterone supplementation within a physiological range is not associated with significantly improved exercise capacity, cardiac function, quality of life, or clinical outcome in CHF patients.

Project description:BackgroundL-carnitine mediates the utilization of fatty acids and glucose in the myocardium. The potential of L-carnitine in managing dilated cardiomyopathy (DCM) in patients has been extensively reported, with additional benefits.ObjectiveThis meta-analysis purposed to explore the clinical efficacy of L-carnitine therapy on DCM patients.MethodsWe searched publications up to May 2020 from several databases including PubMed, Embase, Cochrane Library, Chinese Biomedical (CBM) database, Chinese Science and Technology Periodicals database (VIP), Chinese National Knowledge Infrastructure (CNKI) database, and Wanfang database. Subsequently, publications that met the inclusion criteria were systematically evaluated by two independent reviewers.ResultsA total of 23 RCTs conducted in China with 1455 DCM patients were included in this study. In the meta-analysis, L-carnitine therapy was associated with a considerable improvement in the overall efficacy (RR = 1.28, 95% CI (1.21-1.36), P < 0.0001), left ventricular ejection fraction (LVEF) (MD = 6.16%, 95% CI (4.50, 7.83), P < 0.0001), and cardiac output (CO) (MD = 0.88 L/min, 95% CI (0.51, 1.25), P < 0.0001) as compared to the control group. Moreover, L-carnitine therapy significantly decreased left ventricular end-diastolic dimension (LVEDD) (MD = -2.53, 95% CI (-3.95, -1.12), P = 0.0005), brain natriuretic peptide (BNP) (SMD = -1.71 ng/L, 95% CI (-3.02, -0.40), P = 0.01), and the transforming growth factor-beta (TGF-β1) (MD = -56.78 ng/L, 95% CI (-66.02, -47.53), P < 0.0001).ConclusionsL-carnitine potentially enhanced the therapeutic efficiency in DCM patients. Following weaknesses in the evidence due to low methodological quality and high clinical heterogeneity in the included studies, well-designed trials are recommended.

Project description:Guidelines recommend that exercise training be considered for medically stable outpatients with heart failure. Previous studies have not had adequate statistical power to measure the effects of exercise training on clinical outcomes.To test the efficacy and safety of exercise training among patients with heart failure.Multicenter, randomized controlled trial of 2331 medically stable outpatients with heart failure and reduced ejection fraction. Participants in Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION) were randomized from April 2003 through February 2007 at 82 centers within the United States, Canada, and France; median follow-up was 30 months.Usual care plus aerobic exercise training, consisting of 36 supervised sessions followed by home-based training, or usual care alone.Composite primary end point of all-cause mortality or hospitalization and prespecified secondary end points of all-cause mortality, cardiovascular mortality or cardiovascular hospitalization, and cardiovascular mortality or heart failure hospitalization.The median age was 59 years, 28% were women, and 37% had New York Heart Association class III or IV symptoms. Heart failure etiology was ischemic in 51%, and median left ventricular ejection fraction was 25%. Exercise adherence decreased from a median of 95 minutes per week during months 4 through 6 of follow-up to 74 minutes per week during months 10 through 12. A total of 759 patients (65%) in the exercise training group died or were hospitalized compared with 796 patients (68%) in the usual care group (hazard ratio [HR], 0.93 [95% confidence interval {CI}, 0.84-1.02]; P = .13). There were nonsignificant reductions in the exercise training group for mortality (189 patients [16%] in the exercise training group vs 198 patients [17%] in the usual care group; HR, 0.96 [95% CI, 0.79-1.17]; P = .70), cardiovascular mortality or cardiovascular hospitalization (632 [55%] in the exercise training group vs 677 [58%] in the usual care group; HR, 0.92 [95% CI, 0.83-1.03]; P = .14), and cardiovascular mortality or heart failure hospitalization (344 [30%] in the exercise training group vs 393 [34%] in the usual care group; HR, 0.87 [95% CI, 0.75-1.00]; P = .06). In prespecified supplementary analyses adjusting for highly prognostic baseline characteristics, the HRs were 0.89 (95% CI, 0.81-0.99; P = .03) for all-cause mortality or hospitalization, 0.91 (95% CI, 0.82-1.01; P = .09) for cardiovascular mortality or cardiovascular hospitalization, and 0.85 (95% CI, 0.74-0.99; P = .03) for cardiovascular mortality or heart failure hospitalization. Other adverse events were similar between the groups.In the protocol-specified primary analysis, exercise training resulted in nonsignificant reductions in the primary end point of all-cause mortality or hospitalization and in key secondary clinical end points. After adjustment for highly prognostic predictors of the primary end point, exercise training was associated with modest significant reductions for both all-cause mortality or hospitalization and cardiovascular mortality or heart failure hospitalization.clinicaltrials.gov Identifier: NCT00047437.

Project description:BackgroundIn recent years, there has been growing evidence that vitamin D deficiency is associated with the development and progression of chronic heart failure (CHF).HypothesisAdditional supplementation of vitamin D may have protective effects in patients with CHF.MethodsWe searched PubMed, Embase, and Cochrane databases through June 2015 and included 7 randomized controlled trials that investigated the effects of vitamin D on cardiovascular outcomes in patients with CHF. Then, we performed a meta-analysis of clinical trials to confirm whether vitamin D supplementation is beneficial in CHF patients. The weighted mean difference (WMD) and 95% confidence interval (CI) were calculated using fixed- or random-effects models.ResultsOur pooled results indicated that additional supplementation of vitamin D was not superior to conventional treatment in terms of left ventricular ejection fraction, N-terminal pro-B-type natriuretic peptide, and 6-minute walk distance. Moreover, vitamin D supplementation was associated with significant decreases in the levels of tumor necrosis factor-α (WMD: -2.42 pg/mL, 95% CI: -4.26 to -0.57, P < 0.05), C-reactive protein (WMD: -0.72 mg/L, 95% CI: -1.42 to -0.02, P < 0.05), and parathyroid hormone (WMD: -13.44 pg/mL, 95% CI: -21.22 to -5.67, P < 0.05).ConclusionsVitamin D supplementation may decrease serum levels of parathyroid hormone and inflammatory mediators in CHF patients, whereas it has no beneficial effects on improvement of left ventricular function and exercise tolerance.

Project description:BackgroundHeart failure is the end stage of all cardiovascular diseases, which brings a heavy burden to the global health network. Arotinolol, as a new type of β Receptor blocker, has a good antihypertensive effect. Many clinical trials have observed the clinical efficacy of arotinolol in the treatment of essential hypertension. However, so far, there has been no systematic evaluation on the efficacy and safety of arotinolol in the treatment of chronic heart failure.ObjectiveThe purpose of this review was to systematically evaluate the clinical efficacy of arotinolol in patients with chronic heart failure.MethodsRandomized controlled trials (RCTs) of arotinolol in the treatment of chronic heart failure were retrieved from seven databases according to the Cochrane manual, including CNKI (China National Knowledge Infrastructure), Wan fang database, VIP database, PubMed, Sinomed, EMBASE, and the Cochrane Library databases. The main outcomes were the effective rate, left ventricular ejection fraction (LVEF), blood pressure, heart rate, cardiac index, stroke volume (SV), brain natriuretic peptide (BNP), hypersensitive C-reactive protein (Hs-CRP), left ventricular end diastolic volume (LVEDV), left ventricular end diastolic diameter (LVEDD), and adverse events (AEs).ResultsA total of 17 trials met the qualification criteria, which included 1,717 patients with heart failure. Most trials had uncertain risks in terms of random sequence generation, allocation hiding, patient loss, and result evaluation. Meta analysis showed that arotinolol significantly improved the treatment efficiency of patients with heart failure (standardized mean difference (SMD) = 4.07, 95% confidence interval (CI) [2.89, 5.72], p = 0.00, I 2 = 0), LVEF (SMD = 1.59, 95% CI [0.99, 2.19], p = 0.000 0, I 2 = 95.8%), cardiac index (SMD = 0.32, 95% CI [0.11, 0.53], p = 0.03), I 2 = 0), SV (SMD = 2.00, 95% CI [1.57, 2.34], p = 0.000, I 2 = 64.2%), lower BNP (SMD = -0.804, 95% CI [-0.97, -0.64], p = 0.000, I 2 = 94.4%), and LVEDV (SMD = -0.25, 95% CI [-0.45, -0.05], p = 0.015, I 2 = 0). There was no statistical significance for blood pressure (SMDsystolic pressure = -0.09, 95% CI [-0.69, 0.51], p = 0.775, I 2 systolic pressure = 90.2%; SMDdiastolic pressure = -0.16, 95% CI [-0.79, 0.48], P = 0.632, I 2 diastolic pressure = 91.2%), heart rate (SMD = -0.12, 95% CI [-1.00, 0.75], P = 0.787, I 2 = 96.1%), Hs-CRP (SMD = -1.52, 95% CI [-3.43, 0.40], P = 0.121, I 2 = 98.3%), and LVEDD (SMD = -0.07, 95% CI [-0.90, 0.76], P = 0.870, I 2 = 96.5%).ConclusionArotinolol can safely and effectively improve the effective rate of patients with chronic heart failure, increase LVEF, increase CI and SV, and reduce BNP and LVEDV. However, because of the low overall quality of the included randomized controlled trials, these findings need to be considered carefully. More high-quality randomized controlled trials are needed for further verification, to provide a more scientific basis for the safety and effectiveness of arotinolol in the clinical treatment of heart failure.Systematic review registration[https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=371214], identifier [CRD:420223371214].

Project description:Background: Heart failure as an important issue in global public health, has brought a heavy economic burden. Traditional Chinese medicine injections (TCMIs) have significant effects on heart failure with reduced ejection fraction (HFrEF). However, it is difficult for clinicians to identify the differences in clinical efficacy and safety of various TCMIs. The purpose of this study is to compare the efficacy and safety of various TCMIs for treating HFrEF by conducting a Bayesian network meta-analysis (NMA) and to further provide references for clinical decision-making. Methods: The clinical randomized controlled trials of TCMIs for treating HFrEF were searched in seven database from inception to August 3rd, 2021. The Cochrane collaboration's tool was used to assess the risk of bias. NMA was performed in a Bayesian hierarchical framework. The surface under the cumulative ranking curve (SUCRA), the multi-dimensional efficacy analysis, the comparison-adjusted funnel plot, and the node-splitting analysis were conducted using R software. Results: A total of 107 eligible RCTs involving 9,073 HFrEF patients and 6 TCMIs were included. TCMIs include Huangqi injection (HQ) also called Astragalus injection, Shenfu injection (SF), Shengmai injection (SGM), Shenmai injection (SM), Xinmailong injection (XML), and Yiqifumai lyophilized injection (YQFM). The results of NMA and SUCRA showed that with conventional treatment (CT) as a common control, in terms of clinical efficacy, CT + XML was most effective in New York Heart Association cardiac functional classification efficiency, brain natriuretic peptide, and N-terminal pro-brain natriuretic peptide; the CT + SM was most effective in 6-min walking test, left ventricular end-diastolic diameter, left ventricular end-systolic diameter and cardiac output; the CT + YQFM was most effective in left ventricular ejection fraction; the CT + HQ was most effective in stroke volume; the CT + SF was most effective in Minnesota Living with Heart Failure Questionnaire. In terms of safety, there was no significant difference between CT + TCMIs and CT. Conclusion: This Bayesian network meta-analysis results show that the combination of qualified TCMIs and CT is more effective for HFrEF patients than CT alone, and CT + XML and CT + SM may be one of the potential optimal treatments. Also, the safety of these TCMIs needs to be further observed. However, due to some limitations, the conclusions need to be verified by more large-sample, double-blind, multi-center RCTs.

Project description:Background: Shensong Yangxin capsule (SSYX) is a well-known traditional Chinese patent medicine for treating arrhythmia. Recently, a flurry of randomized controlled trials (RCTs) of SSYX combined with amiodarone (SSYX-amiodarone) was reported in the treatment of heart failure (HF) complicated by ventricular arrhythmia (VA) in China. However, these RCTs have not been systematically evaluated. Therefore, this study aimed to evaluate the efficacy and safety of SSYX-amiodarone in the treatment of heart failure complicated by ventricular arrhythmia (HF-VA). Methods: Seven electronic literature databases (the Cochrane Library, PubMed, EMBASE, China Biomedical database web, China National Knowledge Infrastructure Databases, Chinese Scientific Journal database and Wanfang database) were searched from their inceptions to June 1, 2020 to identify RCTs of SSYX-amiodarone in the treatment of HF-VA. The primary outcomes included the total effective rate and adverse events (ADRs). The secondary outcomes included the frequency of ventricular premature complexes, left ventricular ejection fraction, N terminal pro Btype natriuretic peptide (NT-proBNP), and QT dispersion (QTd). The quality of the included RCTs was assessed using the Cochrane risk-of-bias tool. All data was analyzed using RevMan 5.3 software. The registration number of this protocol is PROSPERO CRD42020196689. Results: There are Eighteen trials involving 1,697 patients were included in this study. Meta-analysis showed that SSYX-amiodarone group was superior to the amiodarone group in improving the total effective rate [RR = 1.21; 95%CI (1.16, 1.27); p < 0.01], meanwhile reducing the ADRs [RR = 0.65; 95%CI (0.45, 0.95); p = 0.03], VPCs [MD = 170.96; 95%CI (159.88, 182.04); p < 0.01] and QTd [MD = 8.39; 95%CI (6.91, 9.87); p < 0.01]. No significant difference of enhancing LVEF [MD = 4.32; 95%CI (-0.56, 9.20); p = 0.08] and reducing NT-proBNP [SMD = 0.17; 95%CI (-0.81, 1.14); p = 0.73] was observed between SSYX-amiodarone and amiodarone group. Conclusions: Despite the apparent positive findings reported, the evidence provided by this meta-analysis was still insufficient to support the routine use of SSYX-amiodarone for HF-VA due to the poor methodological quality of included studies. The overall effect should to be verified in further through more well-design clinical studies with reasonable sample and good methodological quality.

Project description:We conducted meta-analyses of findings from randomized, placebo-controlled, short-term trials for acute mania in manic or mixed states of DSM (III-IV) bipolar I disorder in 56 drug-placebo comparisons of 17 agents from 38 studies involving 10,800 patients. Of drugs tested, 13 (76%) were more effective than placebo: aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperdone, quetiapine, risperidone, tamoxifen, valproate, and ziprasidone. Their pooled effect size for mania improvement (Hedges' g in 48 trials) was 0.42 (confidence interval (CI): 0.36-0.48); pooled responder risk ratio (46 trials) was 1.52 (CI: 1.42-1.62); responder rate difference (RD) was 17% (drug: 48%, placebo: 31%), yielding an estimated number-needed-to-treat of 6 (all p<0.0001). In several direct comparisons, responses to various antipsychotics were somewhat greater or more rapid than lithium, valproate, or carbamazepine; lithium did not differ from valproate, nor did second generation antipsychotics differ from haloperidol. Meta-regression associated higher study site counts, as well as subject number with greater placebo (not drug) response; and higher baseline mania score with greater drug (not placebo) response. Most effective agents had moderate effect-sizes (Hedges' g=0.26-0.46); limited data indicated large effect sizes (Hedges' g=0.51-2.32) for: carbamazepine, cariprazine, haloperidol, risperidone, and tamoxifen. The findings support the efficacy of most clinically used antimanic treatments, but encourage more head-to-head studies and development of agents with even greater efficacy.
