Abstract
BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection affects the cardiovascular system at many levels. It initially infects endothelial cells, inducing marked endothelial damage and inflammation. However, there was no empirical evidence of functional compromise of arterial walls. AIMS AND OBJECTIVE: Our primary objective was to study functional arterial damage in coronavirus disease 2019 (COVID-19) and establish the noninvasive measurement of arterial stiffness as an independent marker of disease severity. MATERIALS AND METHODS: We recorded the arterial stiffness of 23 mild, 21 moderate, and 20 severe COVID-19 patients grouped on the latest National Institute of Health (NIH) severity criteria. We observed arterial stiffness of COVID-19 patients with standard parameters like noninvasive estimated carotid-femoral pulse wave velocity (cfPWV), age-normalized increase in cfPWV (ANI_cfPWV), age-normalized increase in aortic augmentation pressure (ANI_AugP), and heart rate-normalized augmentation index (HRN_ AIx). All the parameters were also corrected for statistically significant confounding factors. RESULTS: <0.0001). The results even after correction for significant confounding factors did not show any considerable change in the increasing trend of arterial stiffness. CONCLUSION: This study establishes the functional deterioration of arteries in proportion to the severity of COVID-19.
