In total, 40 consecutive patients were randomized to receive either intravitreal bevacizumab or ranibizumab. Patients received three consecutive monthly injections of the assigned drug, then continued treatment as needed. Systemic concentrations of high-sensitivity cardiac troponin T and vascular endothelial growth factor were obtained at baseline, week 9, and week 24. Primary endpoint measure was change in high-sensitivity cardiac troponin T levels compared to baseline. Secondary endpoint measure was change in systemic vascular endothelial growth factor levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There was no significant difference in high-sensitivity cardiac troponin T levels over time ( p = 0.227) within each treatment group and no significant difference between treatments at any time point ( p = 0.276). There was a significant decrease in plasma vascular endothelial growth factor levels at week 9 ( p = 0.001) and week 24 ( p &lt; 0.001) compared to baseline. In the ranibizumab group, vascular endothelial growth factor levels were not significantly different at weeks 9 and 24 compared to baseline ( p = 0.708 and p = 0.117, respectively). There was a significant association between the number of bevacizumab injections from weeks 8 to 24 and the decrease in vascular endothelial growth factor levels at week 24 ( R = \u22120.67, p = 0.032). This correlation was not observed in the ranibizumab group ( R = \u22120.341, p = 0.141).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Repeated intravitreal bevacizumab or ranibizumab did not influence serum high-sensitivity cardiac troponin levels.
