Erythrocytosis incidence and thromboembolic risk in heart failure with reduced ejection fraction treated with SGLT2 inhibitors: a nationwide register-based cohort study.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) increase haemoglobin and haematocrit levels, potentially causing secondary erythrocytosis-defined as a haemoglobin level above 16.5 g/dL in men and 16.0 g/dL in women-which is associated with an elevated thromboembolic risk.

Durability of Pulmonary Vein Isolation With the Heliostar Radiofrequency Balloon-The Prospective RABAAF Study With Protocol-Mandated Repeat Electrophysiology Studies.

Introduction: Pulmonary vein isolation (PVI) is the cornerstone in atrial fibrillation (AF) ablation but achieving durable PVI remains a challenge. The radiofrequency balloon (RFB) is a "single-shot" ablation catheter for PVI that offers selective energy titration from 10 surface electrodes and 3D mapping system integration. The durability of RFB PVI has not been investigated.

Disparities in the access to atrial fibrillation ablation in Denmark: who gets ablated, who neglected?

Aims: Atrial fibrillation (AF) is a common arrhythmia associated with reduced quality of life that can lead to serious complications such as stroke and heart failure. Ablation is a safe and effective treatment for AF but is not offered equally to all patients. The aim of this study is to identify demographic groups more or less likely to undergo AF ablation.

Understanding the incidence of atrial fibrillation and stroke in hypertrophic cardiomyopathy patients: insights from Danish nationwide registries.

Aims: The treatment of atrial fibrillation (AF) in hypertrophic cardiomyopathy (HCM) can be challenging since AF aggravates symptoms and increases the risk of stroke. Which factors contribute to the development of AF and stroke in HCM remains unknown. The aim of this study was to determine the incidence of AF and stroke in HCM patients and identify the risk factors.

Effect of early cryoballoon ablation on atrial fibrillation recurrence-A Danish nationwide register study.

Introduction: Cryoballoon ablation is a safe and efficient rhythm control strategy in atrial fibrillation (AF) patients. The impact of time from diagnosis to ablation is unclear. The aim of this study was to examine the impact of timing of first-time cryoballoon ablation on AF recurrence in a nationwide cohort of AF patients.
