Objective: To evaluate whether circulating cardiac troponin I (cTnI) levels are associated with worst outcomes in patients with atrial fibrillation (AF).

Methods: Consecutive patients visiting the emergency room (ER) with a new episode of a previously diagnosed AF or a new diagnosis of AF during ER admission between January 1st, 2010 and December 31st, 2015, were enrolled in the study (n = 2617). After applying exclusion criteria and eliminating repeated episodes, 2013 patients were finally included. Read More

Department of Intensive Care, Rigshospitalet University of Copenhagen, Copenhagen, Denmark.

Background: Coronavirus disease 2019 (COVID-19) may be associated with cardiac arrhythmias in hospitalised patients, but data from the ICU setting are limited. We aimed to describe the epidemiology of cardiac arrhythmias in ICU patients with COVID-19.

Methods: We conducted a multicenter, retrospective cohort study including all ICU patients with an airway sample positive for severe acute respiratory syndrome corona-virus 2 from March 1 to June 1 in the Capital Region of Denmark (1. Read More

Department of Epidemiology, Biostatistics and Evidence-Based Medicine, Al-Farabi Kazakh National University, Almaty, Republic of Kazakhstan.

Background: Electrical isolation of pulmonary vein ostia is an established therapy for paroxysmal atrial fibrillation.

Aims: The purpose of this study is to evaluate the long-term efficacy and safety of cryoballoon catheter ablation in paroxysmal atrial fibrillation with normal anatomy of the left atrium.

Methods: Two hundred fifteen consecutive patients were included in the study (from November 2014 to November 2016). Read More

J Interv Card Electrophysiol 2021 Feb 27. Epub 2021 Feb 27.

Electrophysiology Department, Barts Heart Centre, St. Bartholomew's Hospital, London, UK.

Purpose: A significant proportion of patients undergoing catheter ablation for atrial fibrillation (AF) experience arrhythmia recurrence. This is mostly due to pulmonary vein reconnection (PVR). Whether mapping using High-Density Wave (HDW) technology is superior to standard bipolar (SB) configuration at detecting PVR is unknown. Read More
