Comparison of ischemic stroke risk in atrial fibrillation patients with or without myocardial infarction: a propensity score matched study

초록

Background: Stroke risk in atrial fibrillation (AF) is commonly associated with myocardial infarction (MI). The risk of stroke in AF correlates well with the CHA2DS2VASc score but still have some heterogeneous aspect. Purpose: We investigated whether the presence of prior MI increases stroke risk in AF patients with similar risk degree.
