Abstract Patients with coronavirus disease 2019 (COVID-19) present increased risk for ischemic cardiovascular complications up to 1 year after infection. Although the systemic inflammatory response severe acute respiratory syndrome 2 (SARS-CoV-2) infection likely contributes this risk, whether SARS-CoV-2 directly infects coronary vasculature and attendant atherosclerotic plaques remains unknown. Here we report that viral RNA is detectable replicates in lesions taken at autopsy from COVID-19...

COVID-19 patients present higher risk for myocardial infarction (MI), acute coronary syndrome, and stroke up to 1 year after SARS-CoV-2 infection. While the systemic inflammatory response infection likely contributes this increased cardiovascular risk, whether directly infects vasculature attendant atherosclerotic plaques locally promote inflammation remains unknown. Here, we report that viral RNA (vRNA) is detectable replicates in lesions taken at autopsy from with severe COVID-19....

Background: We describe the implementation of a remote operational model to provide targeted, multi-faceted social services during coronavirus disease 2019 (COVID-19) pandemic at East Harlem Health Outreach Partnership (EHHOP), student-run, physician-supervised free clinic (SRFC) that serves uninsurable residents in New York City (NYC). The attempts mitigate economic consequences while also safely meeting needs patients who were quarantined or otherwise medically vulnerable.
