Cost-Effectiveness Ratio Analysis of LBBaP Versus BVP in Heart Failure Patients With LBBB.

Background: For the initial treatment strategy for patients with cardiac resynchronization therapy (CRT) indications, whether to choose left bundle branch area pacing (LBBaP) or biventricular pacing (BVP) remains controversial. We aimed to investigate the cost-effectiveness ratio (CER) of LBBaP and BVP in heart failure (HF) patients with left bundle branch block (LBBB).

Methods: This observational study included HF patients with LBBB who underwent successful LBBaP or BVP.

New-onset atrial high-rate episodes in left bundle branch area pacing versus right ventricular pacing for patients with atrioventricular block.

Background: Left bundle branch area pacing (LBBAP) demonstrated beneficial effects on clinical outcomes. Comparative data on the risk of atrial high-rate episodes (AHREs) between LBBAP and right ventricular pacing (RVP) are lacking.

Aims: This study aimed to investigate whether LBBAP can reduce the risk of new-onset AHREs compared with RVP in patients with atrioventricular block (AVB).

Empagliflozin ameliorates cardiac dysfunction in heart failure mice via regulating mitochondrial dynamics.

Empagliflozin has cardioprotective effects in patients with heart failure (HF). However, the mechanism by which empagliflozin protects against HF remains controversial. Study aimed to evaluate the effect of empagliflozin on myocardial fibrosis and cardiac function in HF mice and its possible mechanism.

Trimethylamine N-oxide facilitates the progression of atrial fibrillation in rats with type 2 diabetes by aggravating cardiac inflammation and connexin remodeling.

Diabetes is an independent risk factor for atrial fibrillation (AF). This study aimed to elucidate the pathophysiology of diabetes-related AF from the perspective of the gut microbial metabolite trimethylamine N-oxide (TMAO). In the present study, male rats received either a normal diet to serve as the control group or a high-fat diet/streptozotocin to induce type 2 diabetes mellitus.

N(6)-adenosine-methyltransferase-14 promotes glioma tumorigenesis by repressing argininosuccinate synthase 1 expression in an m6A-dependent manner.

Glioma is one of the leading causes of tumor-related deaths worldwide, but its potential mechanism remains unclear. This study aimed to explore the biological role and potential mechanism of argininosuccinate synthase 1 (ASS1) in glioma. The relative expression levels of ASS1 in glioma specimens and cell lines were calculated by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blotting.

LncRNA SNHG5: A new budding star in human cancers.

Long non-coding RNA (LncRNA) belongs to non-coding RNAs longer than 200 nucleic acids. More and more studies have revealed that lncRNA can participate in the occurrence and pathophysiology of diseases, especially in cancers. Although research on lncRNAs has doubled year by year, little is known about the specific regulatory mechanisms of lncRNAs in diseases.

Renal Denervation Attenuates Multi-Organ Fibrosis and Improves Vascular Remodeling in Rats with Transverse Aortic Constriction Induced Cardiomyopathy.

Background/aims: To investigate the effects of renal denervation (RDN) on multi-organ fibrosis and vascular remodeling in cardiomyopathy.

Methods: Thirty-six male Sprague-Dawley rats underwent transverse aortic constriction (TAC). Five weeks later, 28 surviving TAC rats were randomly assigned to three groups: (1) RDN, (2) Sham, (3) Carvedilol.

Renal denervation significantly attenuates cardiorenal fibrosis in rats with sustained pressure overload.

To investigate the effects of renal denervation (RDN) on comprehensive cardiac and renal fibrosis in cardiomyopathy. Five weeks after successful transverse aortic constriction (TAC)-induced cardiomyopathy model building, Sprague-Dawley rats were randomly assigned to three groups: (1) RDN, (2) sham, and (3) losartan. Sham TAC rats served as control group.

[Effects of renal denervation on left atrial fibrosis in rats with isoproterenol induced chronic heart failure].

Objective: To investigate the effects of renal denervation (RDN) on left atrial fibrosis in rats with chronic heart failure.

Methods: Sixty healthy male Sprague Dawley rats were randomly assigned to control group (n=10, intraperitoneal injection with 5 mg/kg normal saline daily for 3 consecutive weeks), sham group (n=25) and RDN group (n=25). Rats in sham and RDN group were intraperitoneally injected with 5 mg/kg isoproterenol daily for 3 consecutive weeks.

Reductions of left ventricular mass and atrial size following renal denervation: a meta-analysis.

Background: Renal denervation (RDN), a novel therapy for resistant hypertension, has been shown to have an effect on cardiac remodeling in several small studies. We aimed to pool currently available data to assess the effects of RDN on left ventricular hypertrophy (LVH) and left atrial (LA) enlargement.

Methods And Results: Two investigators independently searched PubMed, EMBASE and Cochrane Library Central Register of Controlled Trials database for studies reporting change in left ventricular mass index (LVMI) or LA size before and after RDN.

Renal Denervation Findings on Cardiac and Renal Fibrosis in Rats with Isoproterenol Induced Cardiomyopathy.

Cardio-renal fibrosis plays key roles in heart failure and chronic kidney disease. We sought to determine the effects of renal denervation (RDN) on cardiac and renal fibrosis in rats with isoproterenol induced cardiomyopathy. Sixty male Sprague Dawley rats were randomly assigned to Control (n = 10) and isoproterenol (ISO)-induced cardiomyopathy group (n = 50).

Bleeding risks with novel oral anticoagulants during catheter ablation of atrial fibrillation: a systematic review and network meta-analysis.

Background: Comprehensive comparisons of safety (measured by bleeding risk) between multiple novel oral anticoagulants (NOACs and warfarin) in the peri-procedural period of catheter ablation (CA) for atrial fibrillation (AF) are rare.

Methods And Results: MEDLINE, EMBASE, and COCHRANE LIBRARY were searched up to February 2015 by two reviewers independently. Predefined inclusion criteria identified 24 studies which were included in the analysis.
