Insights
Certain COVID-19 patients show heart inflammation and potential myocardial infarction, even with normal coronary arteries. This finding highlights specific cardiac risks associated with the virus.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Imaging
Background:
- Coronaviruses, including SARS-CoV-2, can affect multiple organ systems.
- Cardiac complications are increasingly recognized in COVID-19 patients.
- Myocardial inflammation (myocarditis) is a known cardiac manifestation of viral infections.
Observation:
- A specific cohort of COVID-19 patients underwent cardiac magnetic resonance imaging (CMR).
- These patients displayed evidence of myocardial inflammation on CMR.
- Epicardial coronary arteries were assessed and found to be normal in this subgroup.
Findings:
- Subendocardial fibrosis was observed in the affected patients.
- This pattern of fibrosis is consistent with myocardial infarction (heart attack).
- The presence of fibrosis despite normal coronary arteries suggests non-atherosclerotic causes.
Implications:
- COVID-19 can lead to myocardial infarction through mechanisms independent of epicardial coronary artery disease.
- Cardiac MRI is crucial for diagnosing myocardial inflammation and fibrosis in COVID-19.
- Understanding these cardiac manifestations is vital for patient management and prognosis.
Abstract:
A subgroup of COVID-19 patients with cardiac magnetic resonance imaging evidence of myocardial inflammation may exhibit subendocardial fibrosis, compatible with myocardial infarction, while epicardial coronary arteries are normal.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
