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.

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.

A cost-consequence analysis comparing three cardiac ablation strategies for the treatment of paroxysmal atrial fibrillation.

Background And Aims: Cardiac ablation is a well-established method for treating atrial fibrillation (AF). Pulsed field ablation (PFA) is a non-thermal therapeutic alternative to radiofrequency ablation (RFA) and cryoballoon ablation (CRYO). PFA uses high-voltage electric pulses to target cells.

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.

Two decades of SVT ablation in Denmark: a trend towards higher age, more comorbidity, and less prior use of antiarrhythmic and rate-limiting pharmacotherapy-a nationwide registry-based Danish study.

Background And Aims: Trends in patient selection and use of pharmacotherapy prior to catheter ablation (CA) for supraventricular tachycardia (SVT) are not well described. This study examined temporal trends in patients undergoing first-time CA for regular SVT, including atrioventricular nodal re-entry tachycardia (AVNRT), accessory pathways (APs), and ectopic atrial tachycardia (EAT) on a nationwide scale in Denmark in the period 2001-2018.

Methods And Results: Using Danish Nationwide registers, 9959 patients treated with first-time CA for SVT between 2001 and 2018 were identified, of which 6023 (61%) received CA for AVNRT, 2829 (28%) for AP, and 1107 (11%) for EAT.

Temporal trends of hypertrophic cardiomyopathy in Denmark: a nationwide retrospective cohort study.

Objectives: To describe the population of patients diagnosed with hypertrophic cardiomyopathy (HCM) in Denmark and determine temporal trends in incidence and patient characteristics over time.

Design: Nationwide retrospective cohort study.

Setting: Danish nationwide administrative and clinical registers and databases.
