Retinal artery occlusion should trigger acute vascular ischemic screenings

Posted on

Retinal artery occlusion (RAO) has a significant burden of co-morbidities, death, stroke, myocardial infarction (MI), and readmission and should be used as a clinical marker of future stroke and MI, according to a study.

A nationwide database was searched and instances 14,527 patients with RAO were identified, with a mean age of 69 ± 13 years.

The most common co-morbidities were:
-Hypertension (n = 11,839)
-Hyperlipidemia (n = 8868)
-Ischemic cardiomyopathy (n = 4826)
-Smoking (n = 4772)
-Diabetes (n = 4588)

Overall, RAO, 308 patients (2.1%) died, 1577 (10.9%) developed stroke, and 615 (4.2%) developed MI within 6 months. Approximately, 25% of patients (n =2841) were readmitted within 6 months of discharge, with the most common cause being carotid artery stenosis (n = 386, 10.8%)

Predictors of stroke included history of stroke or transient ischemic attack and Elixhauser co-morbidity index ≥3; predictors of MI included female gender, ischemic cardiomyopathy, carotid artery disease, heart failure, chronic kidney disease, and cancer. Predictors of 6-month all-cause readmission, cancer, chronic kidney disease, Elixhauser co-morbidity index ≥3, Medicare/Medicaid payer status, nonelective index admission, atrial fibrillation, and carotid artery disease.
