High-power short-duration vs conventional radiofrequency ablation for atrial fibrillation in patients over 80 years of age: A propensity-score matched cohort analysis.

Background: Data on atrial fibrillation (AF) ablation using high-power short-duration (HPSD) ablation in patients over 80 years are lacking.

Objective: This study aimed to compare the safety and efficacy of paroxysmal and persistent AF ablation using an HPSD (60-90 W/4-8 sec) vs conventional ablation (30-40 W/30 sec) in a propensity score-matched cohort of patients older than 80 years.

Methods: Overall, 232 consecutive patients aged over 80 years undergoing AF ablation were included.

Magnetoionography enhances diagnostic accuracy of magnetocardiography in coronary artery disease.

Coronary artery disease (CAD) remains a leading cause of morbidity and mortality worldwide. Traditional diagnostic approaches, including coronary angiography and electrocardiography, have limitations in detecting ischemia and microvascular dysfunction, leading to misdiagnoses and unnecessary interventions. This study evaluates the efficacy of magnetoionography (MIG), a novel parameter extension of magnetocardiography (MCG), in improving the detection of CAD by analyzing potential intracellular cardiac currents.

Magnetocardiography at rest predicts cardiac death in patients with acute chest pain.

Introduction: Sudden cardiac arrest is a major cause of morbidity and mortality worldwide and remains a major public health problem for which better non-invasive prediction tools are needed. Primary preventive therapies, such as implantable cardioverter defibrillators, are not personalized and not predictive. Most of these devices do not deliver life-saving therapy during their lifetime.

Mortality and healthcare resource utilisation after cardiac arrest in the United States - A 10-year nationwide analysis prior to the COVID-19 pandemic.

Aim: Understanding the public health burden of cardiac arrest (CA) is important to inform healthcare policies, particularly during healthcare crises such as the COVID-19 pandemic. This study aimed to analyse outcomes of in-hospital mortality and healthcare resource utilisation in adult patients with CA in the United States over the last decade prior to the COVID-19 pandemic.

Methods: The United States (US) National Inpatient Sample was utilised to identify hospitalised adult patients with CA between 2010 and 2019.
