Abstract
The purpose of this study was to calculate and compare individual cardiovascular risk (CVR) and the development of cardiovascular events and mortality in patients with and without ocular pseudoexfoliation (PEX). A cohort study was carried out to compare two groups of patients who underwent cataract surgery: patients with (n = 99) and without PEX (n = 239). The CVR factors were recorded for all the subjects, and CVR was calculated for each individual using ERICE risk assessment charts. After a six-year follow-up, the cardiovascular events and mortality rates were compared between the two groups. The mean CVR was 36.41% in the PEX group and 33.72% in the non-PEX group (p = 0.13). High blood pressure was detected in significantly more PEX patients (71.4%) than non-PEX patients (58.6%, p = 0.035), yet no differences were found in the other CVR factors. The prevalence of cardiovascular events in the PEX and non-PEX patients was 17.1% and 12.5%, respectively (p = 0.26), with 5% of patients in the PEX group and 5% in the non-PEX group suffering an acute coronary event (p = 0.9). Moreover, 12% of the PEX patients and 7.5% of the non-PEX patients experienced a stroke (p = 0.17), and the six-year mortality rate was 29.3% in the PEX group and 25.9% in the non-PEX group (p = 0.52). PEX was associated with high blood pressure in our cohort of patients, although cardiovascular risk was not shown to be higher in this group. In addition, patients with PEX did not experience more cardiovascular events or have a higher mortality rate than patients without PEX during the period studied.
