Aging Modulates the Substrate and Triggers Remodeling in Atrial Fibrillation.
Abstract Aging plays a critical role in the genesis of atrial fibrillation (AF) and also increases the risks of cardiac dysfunction and stroke in AF patients. AF is caused by increased AF triggering from abnormalities of the thoracic vein and/or modulated substrate (atrial) with enhancement of AF maintenance. Clinical and laboratory evidence indicates that aging is significant in the creation of atrial electrical and structural remodeling that leads to increased susceptibility to AF occurrence. Aging is commonly associated with cardiovascular comorbidities, oxidative stress, calcium dysregulation, atrial myopathy ...

Contiguity Between Ablation Lesions and Strict Catheter Stability Settings Assessed by VISITAGTM Module Improve Clinical Outcomes of Paroxysmal Atrial Fibrillation Ablation 　- Results From the VISITALY Study.
CONCLUSIONS: Paroxysmal AF ablation with contact force technology and strict criteria of stability using the VISITAG module was a safe procedure, associated with an improvement in efficiency and a reduction of atrial tachyarrhythmia recurrence at the 12-month follow-up compared with manual annotation. Contiguity between lesions seemed to enhance effectiveness outcomes. PMID: 29415917 [PubMed - as supplied by publisher]

Validation of Conventional Thromboembolic Risk Factors in a Korean Atrial Fibrillation Population 　- Suggestion for a Novel Scoring System, CHA2DS2-VAK.
CONCLUSIONS: Female sex was not associated with TE events in a Korean non-valvular AF population. The novel CHA2DS2-VAK scoring system, with substitution of CKD for female sex, might be more appropriate for the Korean population. PMID: 30282848 [PubMed - as supplied by publisher]

Safety of Anticoagulant Therapy Including Direct Oral Anticoagulants in Patients With Acute Spontaneous Intracerebral Hemorrhage.
CONCLUSIONS: Anticoagulant therapy was conducted for approximately 90% of anticoagulation-indicated patients after a median of 7 days from ICH onset. The predominant anticoagulant medications were DOACs. Anticoagulant therapy started from the acute phase of ICH should be safe. PMID: 30587698 [PubMed - as supplied by publisher]

Poor Quality of Warfarin Treatment Increases the Risk of All Types of Intracranial Hemorrhage in Atrial Fibrillation.
CONCLUSIONS: Poor control of warfarin treatment was associated with elevated risk of ICH. Approximately half of the ICH were traumatic, mainly subdural. PMID: 30686804 [PubMed - as supplied by publisher]

Safety and Efficacy of Low-Dose Prasugrel as Part of Triple Therapy With Aspirin and Oral Anticoagulants in Patients With Atrial Fibrillation Undergoing Percutaneous Coronary Intervention 　- From the TWMU-AF PCI Registry.
CONCLUSIONS: Low-dose prasugrel, as part of triple therapy, did not increase the risk of bleeding compared with clopidogrel. Therefore, it can be an alternative to clopidogrel for patients with AF undergoing PCI. PMID: 30918236 [PubMed - as supplied by publisher]
