Background. The effects of liraglutide treatment on the left ventricular systolic and diastolic function remain unclear. Methods. This meta-analysis was conducted according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. All relevant randomized, placebo-controlled trials (RCTs) were identified by searching PubMed, EMBASE, Cochrane Library, and ISI Web of Science from the establishment to January 2021 without language limitations. The weighted mean difference (WMD) with 95% confidence intervals (CIs) was calculated. Results. Ten placebo-controlled RCTs involving a total of 732 cases were included in the meta-analysis. Compared with the placebo group, liraglutide therapy showed no beneficial effect on the left ventricular ejection fraction (LVEF) at the end of the study (WMD: 2.120, 95% CI: −0.688 to 4.929, P = 0.139 ) and ΔLVEF during the trial period (WMD: −0.651, 95% CI: −1.649 to 0.348, P = 0. 202 ). Similarly, no statistical differences were noted in diastolic function parameters between the two groups, including the value early diastolic filling velocity (E)/the mitral annular early diastolic velocity ( e ′ ) (WMD: −0.763, 95% CI: −2.157 to 0.630, P = 0. 283 ), Δ e ′ (WMD: −0.069, 95% CI: −0.481 to 0.343, P = 0. 742 ), and Δ E / e ′ (WMD: −0.683, 95% CI: −1.663 to 0.298, P = 0. 172 ). Conclusions. Liraglutide treatment did not improve the left ventricular systolic and diastolic function. Given the study’s limitations, further investigation may be warranted.

Background: we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of exercise training on cardiac function and circulating biomarkers outcomes among women with breast cancer (BC) receiving anthracycline or trastuzumab-containing therapy. Methods: PubMed, EMBASE, Cochrane Library, Web of Science and Scopus were searched. The primary outcome was change on left ventricular ejection fraction (LVEF). Secondary outcomes included diastolic function, strain imaging and circulating biomarkers. Results: Four RCTs were included, of those three were conducted during anthracycline and one during trastuzumab, involving 161 patients. All trials provided absolute change in LVEF (%) after a short to medium-term of treatment exposure (≤6 months). Pooled data revealed no differences in LVEF in the exercise group versus control [mean difference (MD): 2.07%; 95% CI: −0.17 to 4.34]. Similar results were observed by pooling data from the three RCTs conducted during anthracycline. Data from trials that implemented interventions with ≥36 exercise sessions (n = 3) showed a significant effect in preventing LVEF decline favoring the exercise (MD: 3.25%; 95% CI: 1.20 to 5.31). No significant changes were observed on secondary outcomes. Conclusions: exercise appears to have a beneficial effect in mitigating LVEF decline and this effect was significant for interventions with ≥36 exercise sessions.

Background. Whether additional benefit can be achieved with the use of L-carnitine (L-C) in patients with chronic heart failure (CHF) remains controversial. We therefore performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the effects of L-C treatment in CHF patients. Methods. Pubmed, Ovid Embase, Web of Science, and Cochrane Library databases, Chinese National Knowledge Infrastructure (CNKI) database, Wanfang database, Chinese Biomedical (CBM) database, and Chinese Science and Technology Periodicals database (VIP) until September 30, 2016, were identified. Studies that met the inclusion criteria were systematically evaluated by two reviewers independently. Results. 17 RCTs with 1625 CHF patients were included in this analysis. L-C treatment in CHF was associated with considerable improvement in overall efficacy (OR = 3.47, P<0.01), left ventricular ejection fraction (LVEF) (WMD: 4.14%, P=0.01), strike volume (SV) (WMD: 8.21 ml, P=0.01), cardiac output (CO) (WMD: 0.88 L/min, P<0.01), and E/A (WMD: 0.23, P<0.01). Moreover, treatment with L-C also resulted in significant decrease in serum levels of BNP (WMD: −124.60 pg/ml, P=0.01), serum levels of NT-proBNP (WMD: −510.36 pg/ml, P<0.01), LVESD (WMD: −4.06 mm, P<0.01), LVEDD (WMD: −4.79 mm, P<0.01), and LVESV (WMD: −20.16 ml, 95% CI: −35.65 to −4.67, P<0.01). However, there were no significant differences in all-cause mortality, 6-minute walk, and adverse events between L-C and control groups. Conclusions. L-C treatment is effective for CHF patients in improving clinical symptoms and cardiac functions, decreasing serum levels of BNP and NT-proBNP. And it has a good tolerance.

Background. Insect drugs have great potential for treating cardiovascular diseases. Xinmailong (XML) injection, a bioactive composite extracted from Periplaneta americana (a species of cockroach), was wildly used in treating heart failure in China. This meta-analysis aimed to assess the efficacy and safety of XML injection for the improvement of cardiac function in HF. Materials and Methods. Online literature search for relevant studies was performed using databases including PubMed, EMBASE, Cochrane Library, CNKI, and Wanfang. Left ventricular ejection fraction (LVEF), six-minute walk test (6MWT), and brain natriuretic peptide (BNP) were selected as target outcomes. The analysis was performed using Stata 12.0, and sources of heterogeneity were explored by subgroup analysis and metaregression. Results. 32 studies were included in this meta-analysis after meeting the inclusion/exclusion criteria. The results demonstrated that additional use of XML improved LVEF (WMD = 5.82, 95% CI: 5.52–7.13, P < 0.00001 ) and 6MWT (WMD = 51.48, 95% CI: 35.83–67.13, P < 0.00001 ) and reduced BNP (WMD = −172.84, 95% CI: −205.79 to −139.89, P < 0.00001 ). The results of subgroup analyses and metaregression suggested that XML injection has more cardiac function improvement for middle-aged HF patients than youth, and greater LVEF and 6MWT improvement were associated with higher average age. Conclusions. XML plus conventional treatment demonstrated a significant effect in reducing cardiac dysfunction in HF patients, and age is a potential factor of higher efficacy. Given the heterogeneity and bias of the included RCTs, large, prospective, rigorous trials are still needed.
