Evaluation of Aortic Elasticity Parameters in Survivors of COVID-19 Using Echocardiography Imaging

Abstract

<b><i>Objective:</i></b> While severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects lung tissue, it may cause direct or indirect damage to the cardiovascular system, and permanent damage may occur. Arterial stiffness is an early indicator of cardiovascular disease risk. The aim of our study was to establish the potential effects of SARS-CoV-2 on the vascular system evaluated by transthoracic echocardiographic examination. <b><i>Subjects and Methods:</i></b> This study compared arterial stiffness between the survivors of COVID-19 and those without a history of COVID-19 infection. The difference in aortic diameter was examined using echocardiography. <b><i>Results:</i></b> The study included 50 patients who survived COVID-19 in the last 3–6 months and 50 age- and gender-matched healthy volunteers. In surviving COVID-19 patients, aortic diastolic diameter in cm ([3.1 ± 0.2] vs. [2.9 ± 0.1], <i>p</i> &#x3c; 0.001), pulse pressure (PP) ([43.02 ± 14.05] vs. [35.74 ± 9.86], <i>p</i> = 0.004), aortic distensibility ([5.61 ± 3.57] vs. [8.31 ± 3.82], <i>p</i> &#x3c; 0.001), aortic strain ([10.56 ± 4.91] vs. [13.88 ± 5.86], <i>p</i> = 0.003), PP/stroke volume index ([1.25 ± 0.47] vs. [0.98 ± 0.28], <i>p</i> = 0.001), and aortic stiffness index ([2.82 ± 0.47] vs. [2.46 ± 0.45], <i>p</i> &#x3c; 0.001) were statistically significant compared to the control group. <b><i>Conclusion:</i></b> SARS-CoV-2 may cause reduced or impaired aortic elasticity parameters linked to impaired arterial wall function in COVID-19 survivors compared with controls.
