Gene Expression NebulasSummary: Cardiac microthrombi have been variably identified at autopsy of Covid-19 decedents. Little is known about the morphologic and molecular changes associated with cardiac microthrombi and whether predictive biomarkers exist. We sought to determine the prevalence, pathogenesis, and biomarker risk factors of Covid-19-associated cardiac microthrombi. In addition to histology and immunohistochemical analyses, we investigated right verticles from 8 Covid-19 decedents via single nuclei RNA sequencing for cell-type specific transcriptional differences between hearts with and without microthrombi, as well as between Covid-19 decedents and publicly available non-Covid-19 donor controls.
Overall Design: Compare differential gene expression in right ventricles of fatal Covid-19 hearts between patients that developed microthrombi and those that did not.
