The R-S difference index: A new electrocardiographic method for differentiating idiopathic premature ventricular contractions originating from the left and right ventricular outflow tracts presenting a left bundle branch block pattern.

Differentiating idiopathic premature ventricular contractions (PVCs) originating from the right and left ventricular outflow tracts with a left bundle branch block (LBBB) morphology is relevant to catheter ablation planning and important for lowering the risk of complications. This study established a novel electrocardiographic (ECG) criterion to discriminate PVCs originating from the septum of the right ventricular outflow tract (s-RVOT) and those originating from the aortic sinus cusp of the left ventricular outflow tract (LVOT-ASC). A total of 259 patients with idiopathic PVCs originating from ventricular outflow tract with a LBBB pattern who underwent successful catheter ablation were retrospectively included.

Clinical Characteristics of Patients with Arrhythmias of the Idiopathic Outflow Tract Ventricular: Age, Gender, Comorbidities, Laboratory Test Results, and Echocardiographic Parameters.

Context: Idiopathic ventricular arrhythmias (IVAs) are a spectrum of ventricular arrhythmia (VA) without structural heart disease (SHD), that includes premature ventricular contractions (PVCs) and ventricular tachycardia (VT). The clinical characteristics of patients with PVCs or VT remain unclear, including distribution of the origin of arrhythmias, age and gender differences, comorbidities, laboratory tests, and electrocardiographic parameters.

Objective: The study intended to compare the clinical characteristics of the right ventricular outflow tract (RVOT)- and left ventricular outflow tract (LVOT)-VT of a large group of consecutive patients, to investigate the distribution of the origin of the arrhythmias, age and gender differences, comorbidities, laboratory-examination results, and echocardiographic parameters.

S-R index in V1/V3 serves as a novel criterion to discriminate idiopathic premature ventricular contractions originating from posteroseptal right ventricular outflow tract versus right coronary cusp.

Aim: The current study aimed to establish a novel electrocardiographic (ECG) criterion for discrimination of idiopathic premature ventricular contractions (PVCs) originating from posteroseptal right ventricular outflow tract (sRVOT-p) versus right coronary cusp (RCC).

Methods: A total of 76 patients with idiopathic PVCs who underwent mapping and successful ablation were retrospectively included. Among them, 37 patients had PVCs from sRVOT-p origin and 39 patients from RCC origin.

circRPS16 Promotes Proliferation and Invasion of Hepatocellular Carcinoma by Sponging miR-876-5p to Upregulate SPINK1.

The roles of serine protease inhibitor Kazal type 1 (SPINK1) in multiple types of cancers have been significantly documented. However, its specific roles in hepatocellular carcinoma (HCC) remain to be investigated. This study found that SPINK1 is upregulated in HCC and its upregulation correlates with poor prognosis.

Lead I R-wave amplitude to distinguish ventricular arrhythmias with lead V transition originating from the left versus right ventricular outflow tract.

Background: The electrophysiology algorithm for localizing left or right origins of outflow tract ventricular arrhythmias (OT-VAs) with lead V transition still needs further investigation in clinical practice.

Hypothesis: Lead I R-wave amplitude is effective in distinguishing the left or right origin of OT-VAs with lead V transition.

Methods: We measured lead I R-wave amplitude in 82 OT-VA patients with lead V transition and a positive complex in lead I who underwent successful catheter ablation from the right ventricular outflow tract (RVOT) and left ventricular outflow tract (LVOT).

Inhibition of the LncRNA Gpr19 attenuates ischemia-reperfusion injury after acute myocardial infarction by inhibiting apoptosis and oxidative stress via the miR-324-5p/Mtfr1 axis.

Reperfusion therapy after acute myocardial infarction (AMI) can effectively restore the blood supply and nutritional support of ischemic myocardium and save the dying myocardium. However, myocardial ischaemia-reperfusion (I/R) injury has become a new threat to reperfusion therapy for AMI. Many long-chain noncoding RNAs (lncRNAs) are dysregulated by I/R damage.

Nitric oxide/cyclic GMP pathway mediates the endothelin-1-upregulation of adiponectin expression in rat cardiomyocytes.

Endothelin-1 (ET-1) serves an important role in the development of cardiac dysfunction and heart failure. ET-1 and angiotensin II (AngII) comprise a mutually reciprocal signalling network in the myocardium and serve similar or additive roles in the development of heart failure. Our previous study previously demonstrated that AngII upregulated the expression of APN in cardiomyocytes through an AngII receptor type 2/nitric oxide (NO)/cyclic GMP(cGMP)-dependent pathway.

Angiotensin II increases secreted frizzled-related protein 5 (sFRP5) expression through AT1 receptor/Rho/ROCK1/JNK signaling in cardiomyocytes.

Secreted frizzled-related protein 5 (sFRP5) is a novel adipokine that functions as an inhibitor of Wnt signaling and is involved in embryonic development, proliferation, atherosclerosis, and apoptosis. Studies have shown that sFRP1-4 is expressed in cardiomyocytes, and sFRP3 and sFRP4 are elevated during heart failure. However, it is unclear whether sFRP5 is expressed in cardiomyocytes or cardiac hypertrophy, and as regards the effects of sFRP5 in the process.

[Correlation study on effects of salvianolate on inflammatory cytokines of patients with acute coronary syndrome].

Objective: To explore effects of salvianolate on inflammatory cytokines (C-reactive protein, resistin, and adiponectin) of patients with acute coronary syndrome (ACS), and to analyze its possible treatment mechanisms for ACS patients.

Methods: Eighty-three inpatients with ACS at the Cardiology Department of our hospital were randomly assigned to the treatment group and the control group from May 2011 to January 2012. Those in the treatment group (42 cases) were treated with routine Western medical treatment and intravenous injection of Salvianolate (200 mg/day), while those in the control group (41 cases) were treated with routine Western medical treatment.

Catheter ablation of persistent atrial fibrillation with and without a history of paroxysmal atrial fibrillation.

Background: It is unclear whether a history of paroxysmal atrial fibrillation (PAF) would impact the effect of catheter ablation on persistent atrial fibrillation (AF). This study aimed to compare the effect of catheter ablation on persistent AF with and without a history of PAF.

Methods: One hundred and eighty-three patients underwent catheter ablation of persistent AF lasting for > 1 month and were reviewed.

Atrium-atrioventricular node block: an unusual complication during catheter ablation of persistent atrial fibrillation.

Ablation of persistent atrial fibrillation is still a challenge for the ablationist. Extensive ablation is required under some conditions and could lead to some unintended complications. Here we report a case of atrium-atrioventricular node block complicating multiple catheter ablation procedures for persistent atrial fibrillation.

Cigarette smoking inhibits the anti-platelet activity of aspirin in patients with coronary heart disease.

Objective: Tobacco smoking results in increased platelet aggregability, which suggests that low-dose aspirin used in common clinical practice may not effectively inhibit platelet activity in smokers with coronary heart disease (CHD). This review was performed to assess the effect of aspirin on platelet aggregation in patients with CHD.

Data Sources: We performed an electronic literature search of MEDLINE (starting from the beginning to March 15, 2009) using the term "smoking" or "tobacco" paired with the following: "platelet", "aspirin" or "coronary heart disease".
