Overexpression of circRNA SNRK targets miR-103-3p to reduce apoptosis and promote cardiac repair through GSK3β/β-catenin pathway in rats with myocardial infarction

Cell Death Discovery, 2021
Ischemic cardiomyopathy seriously endangers human health leading to a poor prognosis. Acute myocardial infarction (AMI) is the primary etiology, and the pathophysiological process concludes with the death of cardiomyocytes caused by acute and persistent ...

Do the predictors of right ventricular pacing-induced cardiomyopathy add up?

Indian Pacing and Electrophysiology Journal, 2021
Objective: Knowledge of factors causing pacing-induced cardiomyopathy (PICM) is incomplete. We sought to estimate the incidence and predisposing factors for PICM and evaluate if the risk they portend adds up.

Zero-fluoroscopy approach for ablation in Wolf -Parkinson – White syndrome during pregnancy

Heart Vessels and Transplantation, 2022
Paroxysmal supraventricular tachycardias during pregnancy are rare; however, it can be a therapeutic challenge because of limitations about use of antiarrhythmic drug therapy and catheter ablation indication, due to the risk of radiation exposure to the ...

Ventricular pacing: to pace or not to pace [PDF]

Europace, 2009
Pacing from the right ventricular apex has been the clinical standard for decades but has recently come into question with a growing trend towards reducing ventricular pacing as much as possible. The earliest devices provided asynchronous ventricular pacing in patients whose indication for pacing was asystolic complete heart block. RV apical pacing was

Aging‐induced atrial fibrosis in If current change and its effect on atrial fibrillation in dogs

Annals of Noninvasive Electrocardiology, 2022
Background Atrial fibrillation (AF) is a very common type of cardiac arrhythmia that threatens public health. Aging is an independent AF risk factor. However, the mechanism of age‐related AF remains unclear.

To pace or not to pace? Or how to pace?

Archive of Clinical Cases, 2017
Chronic apical right ventricular pacing may impair left ventricular function and cause heart failure in patients with indication for antibradycardia pacing and normal left ventricular ejection fraction at baseline, through multiple electro-mechanical changes.

Post–Myocardial Infarction Scar With Fat Deposition Shows Specific Electrophysiological Properties and Worse Outcome After Ventricular Tachycardia Ablation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Fat deposition (FD) is part of the healing process after myocardial infarction. The characteristics of FD and its impact on the outcome in patients undergoing ventricular tachycardia (VT) ablation have not been thoroughly studied.
