GSDMD-mediated pyroptosis dominantly promotes left ventricular remodeling and dysfunction in post-myocardial infarction: a comparison across modes of programmed cell death and mitochondrial involvement

open access: yesJournal of Translational Medicine, 2023
Background Myocardial infarction (MI) has recently accounted for more than one-third of global mortality. Multiple molecular pathological pathways, such as oxidative stress, inflammation, and mitochondrial dysfunction, have been recognized as possible ...

Chronic beta-adrenoceptor blockade and human atrial cell electrophysiology: evidence of pharmacological remodelling [PDF]

open access: yes, 2003
<b>Objective:</b> Chronic beta-adrenoceptor antagonist (β-blocker) treatment reduces the incidence of reversion to AF in patients, possibly via an adaptive myocardial response.

Incorporating Inductances in Tissue-Scale Models of Cardiac Electrophysiology [PDF]

open access: yes, 2017
In standard models of cardiac electrophysiology, including the bidomain and monodomain models, local perturbations can propagate at infinite speed.

Regional differences in APD restitution can initiate wavebreak and re-entry in cardiac tissue: A computational study [PDF]

open access: yes, 2005
Background Regional differences in action potential duration (APD) restitution in the heart favour arrhythmias, but the mechanism is not well understood.

Acute dapagliflozin administration exerts cardioprotective effects in rats with cardiac ischemia/reperfusion injury

open access: yesCardiovascular Diabetology, 2020
Background A sodium-glucose co-transporter 2 (SGLT-2) inhibitor had favorable impact on the attenuation of hyperglycemia together with the severity of heart failure.

Electrocardiographic and electrophysiological characteristics of idiopathic ventricular arrhythmias with acute successful ablation at the superior portion of the mitral annulus

open access: yesBMC Cardiovascular Disorders, 2021
Background We sought to identify the electrocardiographic and electrophysiological characteristics of ventricular arrhythmias (VAs), including idiopathic ventricular tachycardia (VT) and premature ventricular contractions (PVCs), with acute successful ...

Atrial Fibrillation Mechanisms and Implications for Catheter Ablation

open access: yesFrontiers in Physiology, 2018
AF is a heterogeneous rhythm disorder that is related to a wide spectrum of etiologies and has broad clinical presentations. Mechanisms underlying AF are complex and remain incompletely understood despite extensive research.

Natural History of Arrhythmia After Successful Isolation of Pulmonary Veins, Left Atrial Posterior Wall, and Superior Vena Cava in Patients With Paroxysmal Atrial Fibrillation: A Multi‐Center Experience

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background We evaluated long‐term outcome of isolation of pulmonary veins, left atrial posterior wall, and superior vena cava, including time to recurrence and prevalent triggering foci at repeat ablation in patients with paroxysmal atrial fibrillation ...

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]

open access: yes, 2006
We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

open access: yes, 2015
Identification of optimal ablation sites in hearts with infarct-related ventricular tachycardia (VT) remains difficult to achieve with the current catheter-based mapping techniques.
