Ultrasounds show impact of COVID-19 on the heart

Cardiac ultrasounds (also known as echocardiograms) are providing a view of the heart and the impact of the COVID-19 virus on patients. A new study by researchers at Icahn School of Medicine at Mount Sinai identifies different types of cardiac structural damage experienced by COVID-19 patients after cardiac injury that can be associated with deadly conditions including heart attack, pulmonary embolism, heart failure, and myocarditis. These abnormalities are associated with higher risk of death among hospitalized patients. The findings, published the October 26 issue of the Journal of the American College of Cardiology, offer new insights that may help doctors better understand the mechanism of cardiac injury, leading to quicker identification of patients at risk and guidance on future therapies.
