Almost 20% of COVID-19 patients have a history of atrial fibrillation (AF), but also a new-
onset AF represents a frequent complication in COVID-19. Clinical evidence demonstrates …

Interatrial block (IAB) is an electrocardiographic pattern describing the conduction delay
between the right and left atria. IAB is classified into 3 degrees of block that correspond to …

Background Left atrial (LA) fibrosis is a marker of atrial cardiomyopathy and has been
reported to be associated with both atrial fibrillation and ischemic stroke. Elucidating this …

Background Atrial fibrillation (AF) detection and treatment are key elements to reduce
recurrence risk in cryptogenic stroke (CS) with underlying arrhythmia. The purpose of the …

Coronary microvascular dysfunction (CMD) is a clinical entity linked with various risk factors
that significantly affect cardiac morbidity and mortality. Hypertension, one of the most …

Fibrosis has been mechanistically linked to arrhythmogenesis in multiple cardiovascular
conditions, including atrial fibrillation (AF). Previous studies have demonstrated that fibrosis …

Abstract Purpose of Review Atrial fibrillation (AF) is a major risk factor for systemic embolism
and ischaemic stroke. Furthermore, AF-related strokes are associated with higher mortality …

The identification of the pulmonary veins as a trigger source for atrial fibrillation (AF) has
established pulmonary vein isolation (PVI) as a key target for AF ablation. However, PVI …

Objective (s): Irisin was reported as a cardioprotective and anti-oxidative effector, while the
effect on atrial fibrosis is unknown. The current research examined irisin's function in atrial …

Background New-onset atrial fibrillation (NeAF) is common after cavotricuspid isthmus-
dependent counterclockwise atrial flutter (CCW-AFL) ablation. This study aimed to …
