This finding is highly important because these patients remain at a substantial risk for IS even when appropriately treated with oral anticoagulants. Although AF is regarded as a high-risk cardiac source of cerebral embolism, approximately 20% of patients with AF have multiple potential stroke aetiologies. Compared with patients with non-cardioembolic strokes, AF-related strokes constitute the most severe IS subtype, resulting in greater disabilities, higher mortality rates, and higher treatment costs. This finding can possibly be explained by the more frequent occurrence of lacunar strokes in the AFl group compared with that in the AF group.Ītrial fibrillation (AF) and atrial flutter (AFl) are the most common types of atrial arrhythmia (AA) and are both important risk factors for ischaemic stroke (IS). Conclusions: Disabling or fatal IS was observed less often in patients with AFl than in patients with AF. 39.5% in AFl, p < 0.01), and lacunar strokes were the most common in the AFl group (47.4% vs. Most IS cases in the AF group were clas-sified as cardioembolic strokes (74.9% vs. The mean age and prestroke CHA2DS2-VASc scores were similar between the patients with AFl and those with AF. Results: The study groups consisted of 528 patients, including 490 (92.8%) patients with AF and 38 (7.2%) patients with AFl. Material and methods: A retrospective analysis of patients consecutively admitted to a tertiary care centre between 20 due to IS or transient ischaem-ic attack with permanent AFl or permanent or persistent AF was performed. The aim of the present study was to compare the clinical course of IS in patients with AFl and patients with atrial fibrillation (AF).
Introduction: Few studies have explored the potential impact of atrial flutter (AFl) on ischaemic stroke (IS) outcome.
