Abstract
AIM: To identify risk factors for an atherothrombotic event (ATE) among patients who were treated for diabetic macular edema (DME) with intravitreal bevacizumab injections. METHODS: This retrospective study enrolled all consecutive patients with DME who were treated by intravitreal bevacizumab from 2009 through 2016 in a single center. They were divided into one group treated by bevacizumab and subsequently had an ATE and a second group also treated by bevacizumab and did not have an ATE. RESULTS: A total of 455 patients with DME were enrolled. Seventy-two of the patients had an ATE. A multivariate model adjusted for age, gender, smoking, body mass index, hemoglobin A1c (HbA1c), duration of diabetes, creatinine, and blood pressure revealed an increased risk for ATE in the patients with diabetic duration of more than 13y, a systolic blood pressure over 153.5 mm Hg at first treatment, or having been treated by more than 4 intravitreal bevacizumab injections. Additionally, patients that had an ATE within 3mo from the last intravitreal treatment underwent more bevacizumab injections (5.2±3.4 vs 3.07±1.86; P<0.001). CONCLUSION: The risk factors for an ATE identified in this study are systolic blood pressure >153.5 mm Hg, a history of diabetic mellitus for more than 13y, and treatment with more than 4 intravitreal bevacizumab injections. These factors need to be borne in mind when bevacizumab is being considered in the management of patients with DME. International Journal of Ophthalmology Press.
