Infiltrating monocytes drive cardiac dysfunction in a cardiomyocyte-restricted mouse model of SARS-CoV-2 infection.

ABSTRACT: Cardiovascular manifestations of coronavirus disease 2019 (COVID-19) include myocardial injury, heart failure, and myocarditis and are associated with long-term disability and mortality. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA and antigens are found in the myocardium of COVID-19 patients, and human cardiomyocytes are susceptible to infection in cell or organoid cultures. While these observations raise the possibility that cardiomyocyte infection may contribute to the cardiac sequelae of COVID-19, a causal relationship between cardiomyocyte infection and myocardial dysfunction and pathology has not been established. Here, we generated a mouse model of cardiomyocyte-restricted infection by selectively expressing human angiotensin-converting enzyme 2 (hACE2), the SARS
