Why the study?
Does elevated cardiac troponin I predict new-onset atrial fibrillation in patients with acute ischaemic stroke?
Population
402 patients admitted for acute ischaemic stroke with sinus rhythm on admission
Comparison
Elevated cardiac troponin I (cTnI ≥0.03 µg/l) vs Normal cardiac troponin I (<0.03 µg/l)
Design
Cohort

Elevated cTnI may identify acute ischaemic stroke patients at higher AF risk; leaves open whether troponin-guided monitoring improves outcomes.
Does elevated cardiac troponin I predict new-onset atrial fibrillation in patients with acute ischaemic stroke?
Moderately elevated troponin levels in acute ischaemic stroke patients with sinus rhythm on admission independently predict the development of new-onset atrial fibrillation.
