Frequency of cardioversions as an additional risk factor for stroke in atrial fibrillation - the FinCV-4 study.

Background: Patients with atrial fibrillation (AF) are selected for oral anticoagulation based on individual patient characteristics. There is little information on how clinical AF burden associates with the risk of ischaemic stroke or systemic embolism (SSE). The aim of this study was to explore the association of the frequency of cardioversions (CV) as a measure of clinical AF burden on the long-term SSE risk, with a focus on patients at intermediate stroke risk based on CHADS-VASc score.

Adherence to risk-assessment protocols to guide computed tomography pulmonary angiography in patients with suspected pulmonary embolism.

Aims: The use of computed tomography pulmonary angiography (CTPA) in the detection of pulmonary embolism (PE) has considerably increased due developing technology and better availability of imaging. The underuse of pre-test probability scores and overuse of CTPA has been previously reported. We sought to investigate the indications for CTPA at a University Hospital emergency clinic and seek for factors eliciting the potential overuse of CTPA.

Association of Heart Rate With Troponin Levels Among Patients With Symptomatic Atrial Fibrillation.

This cohort study investigates heart rate and cardiac troponin levels in patients admitted to the emergency department with symptomatic atrial fibrillation.

Percutaneous left atrial appendage closure in patients with prior intracranial bleeding and thromboembolism.

Background: Percutaneous left atrial appendage closure (LAAC) is an alternative treatment in atrial fibrillation patients with contraindication to oral anticoagulation. However, patient selection criteria for LAAC are debated.

Objective: The purpose of this study was to evaluate the outcome after LAAC in patients with prior intracranial bleeding and thromboembolism.

Etiology of Minor Troponin Elevations in Patients with Atrial Fibrillation at Emergency Department-Tropo-AF Study.

Patients with atrial fibrillation (AF) presenting to the emergency department (ED) often have elevated cardiac troponin T (TnT) levels without evidence of type 1 myocardial infarction. We sought to explore the causes and significance of minor TnT elevations in patients with AF at the ED. All patients with AF admitted to the ED of Turku University Hospital between 1 March, 2013 and 11 April, 2016, and at least two TnT measurements, were screened.

Effectiveness of Only Aspirin or Clopidogrel Following Percutaneous Left Atrial Appendage Closure.

Percutaneous left atrial appendage closure (LAAC) offers a feasible option for stroke prevention in patients with atrial fibrillation (AF), but the optimal antithrombotic treatment strategy for patients with strict contraindications to oral anticoagulation (OAC) remains uncertain. We sought to evaluate short- and long-term outcome after percutaneous LAAC in these very patients discharged on single antiplatelet therapy (SAPT) alone. All consenting AF patients who underwent LAAC from February 2009 to August 2018 in Turku University Hospital, Finland, were enrolled into a prospectively maintained registry.
