Acute and chronic cardiac involvement in COVID-19

Background Infections with coronavirus disease 2019 (COVID-19) most frequently affect the lungs but may also result in cardiovascular involvement and cardiovascular complications. The heart can either be involved as part of a systemic infection or directly involved due to myocarditis or pericarditis as well as in hypoxia, volume overload, fever or thromboembolic complications. Moreover, pre-existing underlying cardiovascular diseases have a substantial influence on the prognosis of patients with COVID-19 infections. Method This review article is based on a comprehensive literature search in the PubMed database on cardiac involvement and cardiac complications of COVID 19 infections, enriched by experiences in dealing with this disorder. Results and conclusion Depending on the severity of the infection, cardiac involvement in a COVID 19 infection is observed in up to 50% of the patients. Besides echocardiography as the first-line examination method, cardiac magnetic resonance imaging (MRI) for assessment of the myocardial structure and cardiac computed tomography (CT) for assessment of coronary arteries and to rule out intracardiac thrombus formation represent important imaging modalities. The most important cardiac manifestations in COVID 19 infections are ischemic and inflammatory diseases. The imaging diagnostics play an important role in the acute as well as in the postinfectious phases.
