Characterisation of cardiac pathology in 23 autopsies of lethal COVID-19.

ABSTRACT: While coronavirus disease 2019 (COVID-19) primarily affects the respiratory tract, pathophysiological changes of the cardiovascular system remain to be elucidated. We performed a retrospective cardiopathological analysis of the heart and vasculature from 23 autopsies of COVID-19 patients, comparing the findings with control tissue. Myocardium from autopsies of COVID-19 patients was categorised into severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive (n = 14) or negative (n = 9) based on the presence of viral RNA as determined by reverse transcriptase polymerase chain reaction (RT-PCR). Control tissue was selected from autopsies without COVID-19 (n = 10) with similar clinical sequelae. Histological characteristics were scored by ordinal and/or categorical grading. Five RT-
