Background— Catheter ablation of ventricular tachycardia (VT) is effective and particularly
useful in patients with frequent defibrillator interventions. Various substrate modification …

Stroke syndromes present clinically as neurologic deficits of sudden onset. Symptoms depend
upon the affected region of brain, which in turn is defined by the arterial anatomy involved. …

Background— This study aimed to determine 5-year efficacy of catheter ablation for persistent
atrial fibrillation (AF) using AF termination as a procedural end point. Methods and Results…

BACKGROUND: Whether the benefits observed with cardiac resynchronization therapy (CRT)
are similar in patients with versus those without atrial fibrillation (AF) is unclear. …

Objectives : This study sought to evaluate the relationship between fibrosis imaged by
delayed-enhancement (DE) magnetic resonance imaging (MRI) and atrial electrograms (Egms) in …

Registry-based randomized controlled trials are defined as pragmatic trials that use registries
as a platform for case records, data collection, randomization, and follow-up. Recently, the …

Objectives To determine the accuracy of CHADS 2 and CHA 2 DS 2 -VASc tools for predicting
ischaemic stroke or transient ischaemic attack (TIA) and death in patients without a history …

Background The accuracy of current prediction tools for ischaemic and bleeding events
after an acute coronary syndrome (ACS) remains insufficient for individualised patient …

Background: Atrial fibrillation (AF) and heart failure (HF) frequently coexist and can be
challenging to treat. Pharmacologically based rhythm control of AF has not proven to be superior …

Background— Patients who receive implantable cardioverter defibrillator therapies are at
higher risk of death versus those who do not. Programmed settings to reduce nonessential …
