The aim of this study is to identify the factors associated with minor cardiac troponin-T elevations in patients presenting in emergency department (ED) with atrial fibrillation (AF) diagnosis , and the possible implications it has on the patients prognosis. Data on 3394 patients from the Turku university hospital catchment area with diagnosis of AF on admission to ED and minor troponin-T elevation were analyzed. Patients were classified into three groups according to the troponin-T value: troponin <15ng/l, 15-50ng/l and 51-100ng/l. Individual patient records were reviewed.
This study aims at identifying the etiology of troponin-T elevations in patients with atrial fibrillation visiting the emergency department.
