Atrial fibrillation (AF) is a major global health concern impacting millions and causing symptoms like palpitations, dyspnea, fatigue, dizziness, and chest discomfort. Furthermore, these symptoms ...

An in vitro study combining human atrial cardiomyocytes, fibroblasts and intermittent tachypacing reproduced selected electrical, calcium-handling and fibrotic changes associated with atrial ...

Pulsed Field Ablation (PFA) is increasingly used for atrial fibrillation, but the mechanisms of PFA-induced cell death remain incompletely understood. This study aimed to characterize the early ...

Atrial fibrillation is the most common cardiac arrhythmia worldwide and prevalence is expected to continue rising at an exponential rate with an aging population and increasing rates of obesity and ...

Patients with atrial fibrillation (AF) have an increased risk of negative clinical outcomes. In this review article, physicians from the Chinese Academy of Medical Sciences and Peking Union Medical ...

A multidisciplinary team of investigators has engineered a more accurate model for studying the mechanisms underlying atrial fibrillation and its response to treatment, according to findings published ...

New research published in Nature Cardiovascular Research reveals that heart failure and atrial fibrillation share underlying genetic and molecular mechanisms, suggesting that the two cardiovascular ...

A small retrospective cohort linked left atrial reservoir strain and the left atrial volume index-to-ejection-fraction ratio ...

This research letter investigates the cellular mechanisms by which atrial fibrillation (AF) exacerbates ventricular dysfunction in end-stage heart failure (HF), providing mechanistic context for the ...

Introduction: What This Article Covers and What It Does NotWe often see news reports about people who visited a doctor after ...

Atrial fibrillation, or A-fib, is an irregular heart rhythm that increases a person’s risk of stroke, heart failure and even premature death. While many risk factors contribute to A-fib, one stands ...
