We conducted a meta-analysis of the existing literature of the therapeutic effects of using GLP-1 agonists to improve the metabolism of the failing heart. Animal studies showed significant improvement in markers of cardiac function, such as left ventricular ejection fraction (LVEF), with regular GLP-1 agonist infusions. In clinical trials, the potential effects of GLP-1 agonists in improving cardiac function were modest: LVEF improved by 4.4% compared to placebo (95% C.I 1.36–7.44, ). However, BNP levels were not significantly altered by GLP-1 agonists in heart failure. In two trials, a modest increase in heart rate by up to 7 beats per minute was noted, but meta-analysis demonstrated this was not significant statistically. The small number of studies plus variation in the concentration and length of the regime between the trials would limit our conclusions, even though statistically, heterogeneity chi-squared tests did not reveal any significant heterogeneity in the endpoints tested. Moreover, studies in non-diabetics with heart failure yielded conflicting results. In conclusion, the use of GLP-1 agonists has at best a modest effect on ejection fraction improvement in heart failure, but there was no significant improvement in BNP levels in the meta-analysis.

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.

Reduced Ejection Fraction

Introduction: Heart Failure (HF) is categorized according to the AHA/ACC 2013 HF Guidelines based on Left Ventricular Ejection Fraction (LVEF); HF with Reduced Ejection Fraction (HFrEF, EF≤40%), and HF with preserved EF (HFpEF, EF ≥ 50%). There is a group of “borderline” patients with EF 41%-49%, termed Heart Failure with Mid-Range Ejection Fraction (HFmrEF). Given this category is not well understood, we sought to evaluate clinical characteristics and management patterns for patients with HFmrEF. Methods: A systematic review was performed using Ovid MEDLINE, EMBASE, Cochrane CENTRAL and LILACS (1946 – 03/2018). Search terms included HF, mid-range, borderline LVEF with several ranges (40-50 or 40-45 or 45-50). Variables characterizing clinical features and medications were extracted for each HF group and adjusted odds ratios (ORs) were pooled. Results: Of 1,131 abstracts identified, 24 met inclusion criteria (total patients 480,188). Patients with HFmrEF compared to those with HFrEF were more likely to be female (OR 1.42), have hypertension [HTN] (OR 1.34) and diabetes (OR 1.11), higher SBP (OR 1.17), better NYHA-FC (FC I OR 1.73, FC II 1.33), less likely to have coronary artery disease [CAD] (OR 0.74) and more likely to be treated with ACEI, ARB, BB, Digoxin, MRA and statins (Figure 1-2). HFmrEF patients when compared to those with HFpEF were less likely to be female (OR 0.54) or have HTN (OR 0.68), and more likely to have CAD (OR 1.25), and to be treated with HF medications and statins. Conclusions: Patients with HFmrEF have higher SBP and better NYHA-FC (I and II) compared to HFrEF patients and are less likely to be female and more likely to have CAD compared to HFpEF patients. Further research is needed to help guide management in this unique but clinically important population. Figure 1A.

Adaptive Servo Ventilation

Introduction: Central sleep apnea (CSA) is a common complication in heart failure patients (HF) and closely associated with poor prognosis. Adaptive servo-ventilation (ASV) is a new treatment for HF with CSA. Some study indicated ASV might improve cardiac function and its prognosis. However, there was little discussion by each background disease. Methods and Results: We examined 64 HF with CSA patients (involving 15 dilated cardiomyopathy (DCM) patients, 27 ischemic cardiomyopathy (ICM) patients, and 22 heart failure with preserved ejection fraction (HFpEF) patients) treated with ASV who had not been admitted to the hospital due to worsening HF in the 6 months before initiating ASV therapy. During 1 and 6 months observation, apnia-hypopnea index and brain natriuretic peptide were decreased significantly than baseline in all groups. There was similar in left ventricular ejection fraction in ICM and HFpEF groups during observation, however, in DCM group, there was significantly improved (29.3 +/- 14.3 to 36.5 +/- 12.4, and to 40.5 +/- 14.9%, P<0.01 compared with baseline). And left ventricular end systolic diameter was significantly shortened (53.7 +/- 11.1 to 30.4 +/- 11.5, and to 47.6 +/- 12.0 mm, P<0.01 compared with baseline), in spite of left ventricular end diastolic diameter was not changed. Conclusions: These results indicate that ASV is more effective in DCM patient with modifying hemodynamics and cardiac function than ICM and HFpEF patients.
