Insights
Cardiac magnetic resonance (CMR) detected abnormalities in 46% of COVID-19 patients, indicating myocardial damage. While CMR can identify cardiac involvement, no specific imaging features distinguish COVID-19 myocarditis.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Imaging
Background:
- Coronavirus disease 2019 (COVID-19) is known to potentially cause myocardial damage.
- Understanding the cardiac implications of COVID-19 is crucial for patient management.
Purpose of the Study:
- To assess short-term and medium-term outcomes of cardiac involvement in COVID-19 patients.
- To identify characteristic imaging features of COVID-19-related cardiac conditions using cardiac magnetic resonance (CMR).
Main Methods:
- Retrospective analysis of laboratory and CMR findings in 15 COVID-19 patients (May 2020-May 2021).
- Evaluation of late gadolinium enhancement (LGE) for myocarditis.
- Quantitative assessment of cardiac function and comparison with a control group.
- Correlation analysis between high-sensitivity cardiac troponin I (Hs-cTnI), C-reactive protein (CRP), and LGE.
Main Results:
- CMR abnormalities were detected in 46% of COVID-19 patients.
- Late gadolinium enhancement (LGE) was observed in 33% of home-treated and 55.5% of hospitalized patients.
- Elevated Hs-cTnI and CRP levels were noted in hospitalized patients, with a strong correlation between Hs-cTnI and LGE (r=0.63, P<0.001).
- No significant difference in ventricular function was found between COVID-19 and control groups (P<0.001).
Conclusions:
- Cardiac magnetic resonance (CMR) is effective in detecting myocardial abnormalities in COVID-19 patients.
- A significant percentage of COVID-19 patients exhibit CMR-detected cardiac abnormalities.
- No specific diagnostic imaging feature for COVID-19 myocarditis was identified via CMR.
Background:
Coronavirus disease 2019 (COVID-19) may cause myocardial damage.
Purpose:
To evaluate the short-term and medium-term results, as well as the imaging features of COVID-19 cardiac involvement, using cardiac magnetic resonance (CMR).
Material And Methods:
In this study, laboratory and CMR findings of 15 patients with COVID-19 between May 2020 and May 2021 were evaluated retrospectively. Late gadolinium enhancement (LGE) imaging was evaluated for myocarditis. Cardiac functions were quantitatively evaluated and compared to the control patient group. High-sensitivity cardiac troponin I (Hs-cTnI), C-reactive protein (CRP) exchange, and LGE were compared.
Results:
Fifteen patients (7 women; mean age = 38 years) were evaluated. Six patients were treated at home, while nine patients were treated in the hospital. The patients were given remdesivir and hydroxychloroquine treatment. LGE was detected in 2 (33%) patients treated at home and 5 (55.5%) patients treated in the hospital. In hospitalized patients, levels of Hs-cTnI (mean = 7.8 pg/mL) and CRP (mean = 32.3 mg/L) were elevated. A high correlation was observed between the increase in Hs-cTnI value and LGE (r = 0.63; P < 0.001). A low correlation was observed between an increase in CRP and LGE (r = 033; P < 0.001). There was no statistically significant difference in ventricular functions between the COVID-19 and control groups (P < 0.001).
Conclusion:
CMR abnormalities were found in a high percentage (46%) of patients with COVID-19. Myocardial abnormalities in patients with COVID-19 can be detected by CMR. For COVID-19 myocarditis, no specific diagnostic CMR imaging feature was observed.
