Clinical outcome of cardioembolic stroke treated by intravenous thrombolysis
Ischemic stroke (IS) is etiologically a heterogeneous group, and different subtypes are distinguished according to the detected cause. There are strong evidences that intravenous thrombolysis (IVT) in acute ischemic stroke reduces long‐term disability; however, the rate of early mortality remains unchanged.1 Nevertheless, a recent study with 3‐year follow‐up revealed that the longer‐term survival after IVT is increased.3 Etiopathogenetically different stroke subtypes could have diverse outcomes. It has been shown in previous studies that patients with cardioembolic stroke (CS) without IVT may have worse outcomes than those with other subtypes of stroke.4 However, the outcome of CS after treatment with IVT is not adequately evaluated in large‐scale studies.
The aim of this study was to compare the clinical outcome of CS following the IVT with other subtypes of ischemic stroke.
