Insights
Coronary artery calcification in COVID-19 patients is linked to a worse prognosis, but not necessarily increased disease severity. This finding highlights the importance of assessing calcification for predicting outcomes in coronavirus disease-2019 patients.
Area of Science:
- Cardiology
- Infectious Diseases
- Radiology
Background:
- Coronavirus disease-2019 (COVID-19) poses significant global health challenges.
- Coronary artery calcification (CAC) is a marker of atherosclerosis and cardiovascular risk.
- The interplay between COVID-19 and pre-existing cardiovascular conditions like CAC requires further investigation.
Purpose of the Study:
- To investigate the impact of coronary artery calcification on the severity of COVID-19.
- To evaluate the association between coronary artery calcification and the prognosis of COVID-19 patients.
Main Methods:
- A cohort of 141 COVID-19 patients underwent computed tomography (CT) scans.
- Pulmonary involvement severity and coronary artery calcification were assessed using CT.
- Coronary artery calcification was quantified using the Weston and segmental scoring systems, categorizing patients into three groups based on scores.
Main Results:
- A significant difference in pulmonary involvement scores was observed between deceased and discharged patients (P=0.002).
- Patients with lower coronary artery calcification scores (Group 1) had a significantly higher chance of recovery compared to those with higher scores (Group 3) in both scoring systems (P=0.05 and P=0.049, respectively).
- While patients with CAC showed a trend towards more severe disease, this association was not statistically significant (P=0.23 and P=0.79).
Conclusions:
- Coronary artery calcification in COVID-19 patients is significantly associated with a poorer prognosis.
- No significant relationship was found between coronary artery calcification and the severity of COVID-19 disease.
- Assessing CAC may aid in predicting outcomes for patients with COVID-19.
Background:
The aim of this study was to evaluate the effect of coronary artery calcification on disease severity and prognosis in patients with coronavirus disease-2019 (COVID-19).
Materials And Methods:
One hundred and forty-one patients with COVID-19 were included in this study. The severity of pulmonary involvement and calcification of coronary arteries were assessed by computed tomography scan and calcification was classified by two methods: Weston and segmental. In both the methods, patients were divided into three groups with scores of 0, 1-6, and 7-12, which are called groups 1, 2, and 3, respectively.
Results:
The mean age of patients was 54.26 ± 14.55. Difference in score of pulmonary involvement was reported to be significant between deceased and discharged patients (11.73 ± 5.26 and 7.28 ± 4.47, P = 0.002, respectively). In Weston score system, the chance of recovery of Group 1 patients was significantly higher than Group 3 (odds ratio [OR] =6.72, P = 0.05, 95% confidence interval [CI] =1.901-50.257). Similar results were observed in the segmental scoring system (OR =6.34, P = 0.049, 95% CI =1.814-49.416). Despite the higher chance of severe disease in patients with coronary artery calcification, this increase was not statistically significant in either Weston or segmental methods (OR =0.47, P = 0.23 and OR =0.85, P = 0.79, respectively).
Conclusion:
Coronary artery calcification in patients with COVID-19 has a significant association with poor prognosis. However, no significant relationship was observed between this issue and the severity.
