Atrial Fibrillation Management and Outcomes

Background: Arrhythmia recurrence after cryoballoon ablation remains a clinically relevant problem in atrial fibrillation (AF). However, factors associated with documented recurrence in low-risk patients without major comorbidities are not well defined. This study aimed to evaluate factors associated with documented a…

Background/Objectives: Arrhythmia recurrence after cryoballoon ablation is commonly linked to persistent atrial fibrillation (AF), atrial enlargement, aging, obesity, inflammation, renal dysfunction, and accumulated cardiovascular comorbidity. Whether these predictors retain their value when the usual systemic risk dr…

Background: Embolic stroke of undetermined source (ESUS) accounts for up to one quarter of ischemic strokes, with occult atrial fibrillation (AF) as a key underlying cause. Implantable cardiac monitors (ICMs) markedly improve AF detection but are limited by cost and resource demands. Existing AF-prediction models show…

Introduction: Postoperative atrial fibrillation (POAF) is a common complication after coronary artery bypass grafting (CABG), with incidence rates reported between 20% and 40%. Pain and hypoxia related to intercostal chest tube placement may play a role in the development of POAF. This study sought to compare the impa…

Objective: Complete atrioventricular (AV) block complicates management decisions, particularly regarding temporary pacemaker (TP) insertion.Lactate, an anaerobic byproduct, may reflect inadequate cardiac output and help guide this decision.We analyzed the prognostic value of lactate in patients with complete AV block.…

BACKGROUND: The presence of an atrial level right to left shunt may be desirable in patients with severe pulmonary hypertension (PH) or failing Fontan circulation. The Occlutech Atrial Flow Regulator (AFR) was originally designed to create an atrial shunt for left heart failure and is currently being used off-label in…

Objectives: This multicenter study aimed to identify the clinical, laboratory, and demographic determinants associated with stroke recurrence in a large nationwide cohort of patients presenting with acute stroke. Patients and methods: This retrospective multicenter cohort study included 1,132 patients (614 males, 518…

Background and objectives: Paroxysmal atrial fibrillation (PAF) is a common arrhythmia associated with adverse cardiovascular outcomes. Inflammation and nutritional imbalance contribute to arrhythmogenesis. The Naples Prognostic Score (NPS), derived from inflammatory and nutritional laboratory markers, has shown progn…

OBJECTIVES: This study investigates the feasibility of using photoplethysmography (PPG) signals for supporting mitral regurgitation (MR) assessment and monitoring using machine learning techniques. METHODS: MR occurs when blood flows backward from the left ventricle to the left atrium due to mitral valve insufficiency…
