Abstract
PURPOSE: It was aimed to compare corneal endothelial changes during the initial 12-month period in which patients started using atorvastatin after a diagnosis of acute coronary syndrome (ACS). METHODS: Forty-six participants (group 1) who underwent cardiac angioplasty and stenting for ACS and started using 80 mg atorvastatin in the early period were included in the study. In the study, a control group comprising 71 healthy adults (group 2) was included. These individuals did not use medication for any known systemic disease, had never taken statins, had no history of ocular surgery, and did not have any cornea-related eye diseases. Baseline and 12th month endothelial evaluations of group 1 and 2 participants were compared using specular microscopy. RESULTS: There were 28 female and 18 male participants in group 1 and 48 female and 23 male participants in group 2 (P = 0.455). The mean baseline corneal endothelial cell density (CECD) was not significantly higher in group 1 compared to group 2 (2471.4 ± 200 cells/mm2 vs 2428.2 ± 539.8 cells/mm2, P = 0.230). When the change between baseline and 12th month CECD was examined, the decrease in group 2 was significantly different from that in group 1 (-15,2 ± 31,9 and -44,8 ± 49,6, P = 0,002). Although the percentage of hexagonal cells decreased significantly in group 2 participants, no significant change was observed in group 1 (respectively; P < 0.001, P = 0.073). The endothelial cell coefficient of variation did not differ significantly in group 1 participants over a 1-year period (P = 0.192), and a significant increase was observed in group 2 (P < 0.001). CONCLUSION: This study revealed that atorvastatin may have a positive effect on corneal endothelium cell density and morphology.
