BACKGROUND: Atherosclerosis is a chronic inflammatory condition that underlies both cardiovascular and cerebrovascular complications. Emerging evidence suggests that COVID-19 may play a role in its progression.
PURPOSE: The aim of the study was to evaluate the potential impact of SARS-CoV-2 infection on the development of atherosclerosis.
PATIENTS AND METHODS: Common carotid artery (CCA) intima media thickness (IMT) was measured by ultrasonography twice, 12-18 months apart, in a cohort of 92 patients (47 with COVID-19 and 45 controls). Clinical data were collected from medical histories, physical examinations, and laboratory findings.
RESULTS: Baseline IMT values were comparable between the study groups (0.85 mm vs. 0.78 mm). However, the COVID-19 group exhibited a significantly greater increase in IMT over time, with a median change of 0.13 mm compared to 0.05 mm in the controls (p = 0.018). Furthermore, 69.2% of COVID-19 patients exceeded the median IMT progression threshold compared to 36% in the control group (p = 0.017). An elevated level of C-reactive protein (CRP) and a higher triglyceride (Tg)-to-High-Density Lipoprotein Cholesterol (HDL) ratio were significantly associated with increased IMT in the COVID-19 group. Age and heart rate were identified as significant predictors of IMT progression across both groups.
CONCLUSIONS: COVID-19 may accelerate the progression of subclinical atherosclerosis. The strong associations of CRP and the TG/HDL ratio with IMT highlight the potential roles of chronic inflammation and metabolic dysregulation in driving these vascular changes. Further large-scale, multicenter studies are needed to elucidate the underlying mechanisms, confirm these observations, and guide targeted preventive and therapeutic strategies for individuals with an increased cardiovascular and cerebrovascular risk.
