Insights
Carotid ultrasound revealed vascular abnormalities in COVID-19 patients. Increased intima-media thickness combined with kidney damage significantly increased mortality risk in hospitalized coronavirus disease 2019 patients.
Area of Science:
- Vascular Ultrasound
- Cardiovascular Medicine
- Infectious Diseases
Background:
- Hospitalized patients with severe coronavirus disease 2019 (COVID-19) face significant mortality risks.
- Vascular and perivascular abnormalities may contribute to adverse outcomes in COVID-19.
- Carotid arteries are accessible for ultrasound evaluation.
Purpose of the Study:
- To investigate vascular and perivascular abnormalities in carotid arteries of hospitalized COVID-19 patients using ultrasound.
- To evaluate the association of these abnormalities with mortality and clinical variables.
Main Methods:
- Prospective study of 53 hospitalized patients with severe COVID-19.
- Carotid ultrasound examinations were performed.
- Clinical, demographic, laboratory, and imaging data were collected and statistically analyzed.
Main Results:
- Carotid ultrasound showed luminal surface irregularity (55%), carotid plaques (57%), perivascular infiltration (8%), and increased intima-media thickness (IMT) (58%).
- Increased IMT was significantly associated with COVID-19-related mortality (p=0.03).
- Increased IMT combined with kidney damage (acute kidney injury or chronic kidney disease) significantly increased mortality risk (p<0.05).
Conclusions:
- Carotid ultrasound can detect vascular and perivascular abnormalities in severe COVID-19.
- Increased IMT and kidney damage are significant predictors of mortality in these patients.
Objective:
To investigate vascular and perivascular abnormalities in the carotid arteries using ultrasound, as well as to evaluate their association with mortality and clinical variables in hospitalized patients with coronavirus disease 2019 (COVID-19).
Materials And Methods:
This was a prospective study in which 53 hospitalized patients with severe COVID-19 were evaluated and underwent carotid ultrasound. We documented the carotid ultrasound findings in these patients. Clinical, demographic, laboratory, and imaging features were analyzed and compared by statistical analysis to detect correlations between them.
Results:
Carotid ultrasound demonstrated luminal surface irregularity in 29 patients (55%), carotid plaques in 30 (57%), perivascular infiltration in four (8%), and increased intima-media thickness (IMT) in 31 (58%). Of the 31 patients with increased IMT, 19 (61%) died, and the association between increased IMT and COVID-19-related mortality was significant (p = 0.03). Logistic regression showed that the risk of death was 85% in patients who had increased IMT in combination with acute kidney injury at admission or a history of chronic kidney disease (p < 0.05).
Conclusion:
In hospitalized patients with severe COVID-19, carotid ultrasound can show increased IMT, luminal surface irregularity, carotid plaques, and perivascular infiltrates. The combination of increased IMT and kidney damage appears to increase the risk of death in such patients.
