Early detection of stroke at the sudden sensorineural hearing loss stage.

Background And Purpose: Sudden sensorineural hearing loss (SSNHL) can be a prodromal symptom of ischemic stroke, especially posterior circulation strokes in the anterior inferior cerebellar artery (AICA) area. Early diagnosis and optimal treatment for vascular SSNHL provide an opportunity to prevent more extensive area infarction. The objective of our research was to find clues that suggest stroke at the stage of isolated sudden hearing loss.

Association between Fibrinogen-to-Albumin Ratio and Adverse Stroke Outcomes among Patients with Acute Ischemic Stroke.

Introduction: Fibrinogen-to-albumin ratio (FAR) is implicated in prothrombotic states and is associated with an increased risk of acute ischemic stroke (AIS). However, studies investigating whether the prothrombotic effect of FAR is associated with long-term adverse outcomes in patients with AIS are lacking. Therefore, we aimed to investigate the association based on the Third China National Stroke Registry (CNSR-III).
