Abstract

Background: Chronic inflammation is associated with accelerated atherosclerosis, endothelial dysfunction (ED), and cardiovascular diseases. Because chronic rhinosinusitis (CRS) is an inflammatory disease, it may be associated with the development of ED and accelerated atherosclerosis.
Objective: To investigate the relationship between CRS and carotid intima-media thickness (CIMT), flow-mediated dilation (FMD) of the brachial artery, and microalbuminuria.
Materials and Methods: This cross-sectional study included 38 patients with CRS and 29 healthy controls. In addition to measuring spot urine albumin-creatinine ratios, FMD of the brachial artery and CIMT were assessed noninvasively.
Results: Patients with CRS had lower FMD scores (p = 0.031), higher CIMT scores (p = 0.005), and a higher urinary albumin-creatinine ratio (p = 0.036) compared with healthy controls. In a multivariate analysis, CIMT and FMD were independently associated with the presence of CRS. However, the relationship between urinary albumin and creatinine, and the presence of CRS was no longer observed.
Conclusions: CRS is associated with ED and atherosclerosis, as indicated by decreased FMD and increased CIMT in patients with CRS. Further studies are necessary to identify the exact pathophysiologic mechanisms responsible for our findings.
