Stroke Risk and Risk Factors in Patients With Central Retinal Artery Occlusion

American Journal of Ophthalmology

Abstract

Central retinal artery occlusion (CRAO) is mechanistically similar to a stroke. Current guidelines recommend a standardized and systematic evaluation of risk factors for patients who have had a stroke. This study evaluates the yield of this evaluation in patients with CRAO and frequency of stroke in this population. Cohort study. We evaluated the diagnostic yield of an expedited inpatient evaluation of cerebrovascular risk factors in a cohort of patients presenting with an acute CRAO within the period from 2009 to 2017 at an academic hospital. Vital signs and laboratory parameters, including low-density lipoprotein level, hemoglobin A1c fraction, erythrocyte sedimentation rate, C-reactive protein level, platelet count, and troponin level, were collected. Echocardiography, cardiac telemetry, magnetic resonance imaging (MRI), and cerebrovascular imaging were obtained to screen for strokes and vascular risk factors. All new diagnoses and clinical treatments stemming from the inpatient evaluation were documented. Outcomes included the frequency of stroke on MRI, hypertensive emergency, critical carotid disease, or critical cardiac disease, including high-grade valvular lesions, new myocardial infarction, or arrhythmias. We document...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
