Clinical Outcome of Cryoballoon Ablation for Long-Standing Persistent Atrial Fibrillation: From the Korean Cryballoon Ablation Registry.

Introduction: Pulmonary vein isolation (PVI) by cryoballoon ablation (CBA) is considered an effective primary strategy for early persistent atrial fibrillation (AF). However, data regarding CBA for long-standing persistent AF (PeAF) are limited. We evaluated the efficacy and safety of CBA for long-standing PeAF compared to PeAF.

Intensive blood pressure lowering in acute stroke with intracranial stenosis post-thrombectomy: A secondary analysis of the OPTIMAL-BP trial.

Background: Intensive blood pressure (BP) management within 24 h after successful reperfusion following endovascular thrombectomy (EVT) is associated with worse functional outcomes than conventional BP management in Asian randomized controlled trials. Given the high prevalence of intracranial atherosclerotic stenosis (ICAS) in Asia, ICAS may influence these outcomes.

Aims: We aimed to assess whether ICAS affects the outcomes of intensive BP management after successful EVT.
