BACKGROUND: In about one third of all patients with cerebral ischemia, no definite cause can be identified (cryptogenic stroke). In many patients with initially suspected cryptogenic stroke, however, a cardiogenic etiology can eventually be determined. Hence, the aim of this study was to describe the prevalence of abnormal echocardiographic findings ...

BACKGROUND: One of the leading causes of mortality worldwide is ischemic stroke, which is a major contributor to neurological disability and dementia. Terutroban is a specific thromboxane A2 receptor antagonist with antithrombotic, antivasoconstrictive, and antiatherosclerotic properties, which make it a promising tool for secondary prevention of ischemic stroke. METHODS AND ...

Lacunar stroke is associated with an intrinsic cerebral small vessel disorder of unknown etiology, although possible causes include increased blood-brain barrier permeability. Retinal arterioles are similar to cerebral small vessels and retinopathy occurs secondary to increased blood-retinal barrier permeability. We hypothesized that there would be higher rates of retinopathy in ...
