Atrial structural remodeling takes on a critical significance to the occurrence and maintenance of atrial fibrillation (AF). As revealed by recent data, insulin-like growth factor-1 receptor (IGF-1R) plays a certain role in tissue fibrosis. In this study, the mechanism of IGF-1R in atrial structural remodeling was examined based on in vivo and in vitro experiments.

Purpose: Delayed re-endothelialization after coronary drug-eluting stent implantation is associated with an increased incidence of late in-stent thrombosis. Serum exosomes exhibit controversial effects on promoting endothelialization. This study aimed to compare the angiogenic effects of serum exosomes derived from patients with acute myocardial infarction (AMI) and AMI plus diabetes mellitus (DM) and to explore the underlying mechanisms.

Inflammation is an important driver of atherosclerosis. Succinate is a new extracellular inflammatory alarm released by activated macrophages. Succinate is sensed by succinate receptor 1 (Sucnr1) and then transferred to effector cells.

This was a meta-analysis of randomized control trials (RCTs) to evaluate the effect of ivabradine on the risk of atrial fibrillation (AF) and its effect on the ventricular rate in patients with AF. The PubMed, EMBASE, Cochrane Controlled Trials Register, and other databases were searched for RCTs on ivabradine. Thirteen trials with 37,533 patients met the inclusion criteria.

The electrowetting behavior of ionic liquid significantly promotes microfluidic technology due to the advantage of manipulation of ionic liquid without additional mechanical parts. Recently, a novel micro-valve that shows good prospects was proposed by MacArthur et al. based on the permeation of ionic liquid under electric field.

Cardiovascular disease (CAD) is a devastating illness, but to date there are limited means of predicting a person's coronary stenosis severity and their prognosis. The study was performed to investigate the relationship between dipeptidyl peptidase 4(DPP4) gene polymorphisms and serum lipid profiles, as well as the severity of coronary artery stenosis in patients with CAD and type 2 diabetes (T2DM) for the first time.Herein, 201 patients with CAD and T2DM were enrolled in the Department of Cardiology, Shandong Provincial Qianfoshan Hospital.

Delayed endothelial healing after drug eluting stent (DES) implantation is a critical clinical problem in treatment of coronary artery diseases. Exosomes exhibit proangiogenic potential in a variety of ischemic diseases. However, the association of exosomes with endothelial regeneration after DES implantation has been rarely reported.

Because of its unique properties, plasma technology has gained much prominence in the microelectronics industry. Recently, environmental and energy applications of plasmas have gained a lot of attention. In this area, the focus is on converting CO and reforming hydrocarbons, with the goal of developing an efficient single-step 'gas-to-liquid' (GTL) process.

Electrical remodeling has been reported to play a major role in the initiation and maintenance of atrial fibrillation (AF). Long non-coding RNAs (lncRNAs) have been increasingly recognized as contributors to the pathology of heart diseases. However, the roles and mechanisms of lncRNAs in electrical remodeling during AF remain unknown.

Low-temperature plasmas are gaining a lot of interest for environmental and energy applications. A large research field in these applications is the conversion of CO into chemicals and fuels. Since CO is a very stable molecule, a key performance indicator for the research on plasma-based CO conversion is the energy efficiency.

The conversion of atmospheric nitrogen into valuable compounds, that is, so-called nitrogen fixation, is gaining increased interest, owing to the essential role in the nitrogen cycle of the biosphere. Plasma technology, and more specifically gliding arc plasma, has great potential in this area, but little is known about the underlying mechanisms. Therefore, we developed a detailed chemical kinetics model for a pulsed-power gliding-arc reactor operating at atmospheric pressure for nitrogen oxide synthesis.

Aims: The meta-analysis was aimed to search for candidate blood markers whose pre-ablation level was associated with atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA).

Methods And Results: A systematic literature search of PubMed, EMBASE, Springer Link, Web of Science, Wiley-Cochrane library, and supplemented with Google scholar search engine was performed. Thirty-six studies covering 11 blood markers were qualified for this meta-analysis.

Background: The study aimed to observe the effects of pacing on the atrial effective refractory period (AERP), inducibility of atrial fibrillation (AF), and changes of atrial autonomic neural remodeling (ANR) by rosuvastatin intervention on the acute model of rapid-pacing-induced AF.

Methods: Thirty rabbits were randomly divided into a control group (C, n = 10), rapid-pacing group (P, n = 10), and rosuvastatin-intervention group (R, n = 10). AERP and inducibility of AF were measured for all groups.

Background: Long-term effects of ganglionated plexi (GP) ablation on sinoatrial node (SAN) and atrioventricular node (AVN) remain unclear. This study is to investigate the long-term effects of ablation of cardiac anterior right GP (ARGP) and inferior right GP (IRGP) on function and structure of SAN and AVN in canine.

Methods: Thirty-two dogs were randomly divided into an operated group (n = 24) and sham-operated group (n = 8).

Background: The long-term effects of ganglionated plexi ablation on electrophysiological characteristics and neuron remodeling in target atrial tissues remain unclear.

Methods And Results: Dogs in group 1 (control, n=8) were not subjected to ganglionated plexi ablation and observed for 1 month, and dogs in groups 2 to 4 (ablation groups, n=8 each) underwent ablation of the right-sided ganglionated plexi and observed for 1, 6, and 12 months, respectively. Atrial electrophysiological characteristics were examined before ablation, immediately and continuously after ablation.

Article Synopsis
  • Researchers found that special types of RNA, called lncRNAs, might be related to a heart problem called atrial fibrillation (AF), which affects how the heart beats.
  • In their study, they looked at the RNA from dog heart fat and found a lot of lncRNAs with some that were way more active or less active in dogs with AF.
  • They discovered two new lncRNAs that can change how easily AF can start, which means they could be important for creating treatments for this heart condition.

The perioperative anticoagulation strategy during cardiac implantable electronic devices (CIEDs) implantation is highly variable without consensus among implanting physicians. A systematic literature search was performed in MEDLINE, EMBASE, and the Cochrane Library to identify clinical trials in patients on chronic oral anticoagulant (OAC) therapy undergoing CIEDs implantation. Bleeding and thromboembolic events were compared among heparin bridging, continued OAC, and interrupted OAC groups.

Article Synopsis
  • The study looked at how a special molecule called miR-1 affects heart rhythms during a condition known as atrial fibrillation.
  • Researchers found that increasing miR-1 levels made certain genes (KCNE1 and KCNB2) less active, which changed the electrical signals in the heart.
  • This could help understand ways to treat atrial fibrillation by focusing on miR-1 as a potential target for therapy.

Background: A meta-analysis of randomized controlled trials (RCTs) was conducted to compare the effects of right ventricular nonapical (RVNA) and right ventricular apical (RVA) pacing on cardiac function.

Methods: A systematic literature search was performed using MEDLINE, EMBASE, and the Cochrane Library to identify RCTs comparing RVNA pacing with RVA pacing with follow-up ≥2 months. Twenty RCTs involving 1,114 patients were included.
