COVID-19 patients likewise revealed no indications of capillary clogs in their coronary arteries.
The team at LSU says that the damage done to the hearts of COVID-19 patients is not constant with typical heart muscle swelling patterns seen with myocarditis (heart muscle swelling). Rather, the observed pattern of cell death is quite special, and spread across scattered, individual heart muscle cells.
Furthermore, the pathologists likewise keep in mind SARS-CoV-2 was not present in any heart muscle cells. This is particularly odd because the very first SARS coronavirus from 2003 was discovered within the heart muscle cells of SARS patients.
Medical professionals say damage seen in deceased coronavirus patients not constant with common heart muscle inflammation patterns.
” We determined crucial gross and microscopic modifications that challenge the notion that common myocarditis exists in serious SARS-CoV-2 infection,” states Dr. Richard Vander Heide, teacher and Director of Pathology Research at LSU Health New Orleans School of Medicine, in a release. “While the mechanism of heart injury in COVID-19 is unknown, we propose numerous theories that bear additional investigation that will lead to higher understanding and prospective treatment interventions.”
BRAND-NEW ORLEANS– Its become rather evident the previous couple of months that COVID-19 can have a negative impact on the heart. Still, researchers and doctors are still struggling to completely understand the relationship in between COVID-19 and heart health. Now, a series of autopsies performed by Louisiana State University pathologists yield some uncommon observations.
Extreme tension on heart
“Given that inflammatory cells can travel through the heart without existing in the tissue appropriate, a role for cytokine-induced endothelial damage can not be dismissed,” Dr. Heide concludes.
Diffuse alveolar damage (DAD), or damage to the small lung airspaces that help with the exchange of gas, was observed amongst the autopsied clients. All of these aspects were identified to be significant contributors to the clients deaths.
“These findings, in addition to severely enlarged ideal ventricles, may show severe stress on the heart secondary to intense lung illness,” states Dr. Sharon Fox, Associate Director of Research and Development in the Department of Pathology at the school.
The “cytokine storm,” or overreaction of the immune system to the infection, may also add to these observations.

The study is published in Circulation.
All of those patients had passed away due to COVID-19 while being dealt with at the University Medical Center in New Orleans. Most of the clients are African-American, with 10 being male and 12 being female.
Pathologists also indicate viral infections amongst cells in the lining of the smaller blood vessels (endothelium) of clients. While these infections were at reasonably “low levels,” the group at LSU theorize it may have been enough to induce specific cell death.

NEW ORLEANS– Its become quite obvious the past couple of months that COVID-19 can have an adverse impact on the heart. Still, scientists and medical professionals are still struggling to totally comprehend the relationship between COVID-19 and heart health. All of those patients had actually passed away due to COVID-19 while being treated at the University Medical Center in New Orleans. Diffuse alveolar damage (DAD), or damage to the little lung airspaces that help with the exchange of gas, was observed amongst the autopsied clients. All of these aspects were figured out to be major contributors to the patients deaths.
