mbers in the heart, which is very abnormal,” she added. “We don’t know the reason why, but the connection to the clotting is that megakaryocytes produce platelets, and platelets are one of the things that are responsible for clotting.”
Rapkiewicz said more research is needed to determine this connection as it relates to the novel coronavirus, but that “it doesn’t just seem circumstantial.”
Some of the patients in the autopsy study had received blood thinners, such as anticoagulant medications like heparin. But the findings suggest clinicians may need to consider additional treatments or anti-platelet therapies for COVID patients that target smaller blood vessels.
“I think we still need those drugs because the patients that I autopsied who had received anticoagulation really did have less clotting in the big vessels, but they still had clotting in the small vessels. So we need to target the small vessels,” she said.
Scientists around the world have been racing to better understand how SARS-CoV-2, the virus that causes COVID-19, impacts the body. Worrying reports have indicated that the virus may be capable of inflicting long-lasting damage to many areas, including the lungs, nervous system and kidneys.
A recent study led by researchers at University College London described more than 40 patients with COVID-19 who experienced a multitude of different brain effects, including severe neurological complications such as delirium, brain inflammation, stroke and nerve damage.
In another study published in June, more than half of the COVID-19 patients involved were found to have some form of cardiovascular damage.
“I think there still needs to be some very basic science studies into the biology of COVID,” Rapkiewicz said, who added that the aim of her study and others like it is for researchers to better understand how to prevent these severe complications reported in some patients.
“I have a lot of phone calls with people at Johns Hopkins and people in (Massachusetts) General about what could be the underlying thing that's causing the clotting, and that’s really important in the sense that it’s not going to prevent COVID. We're just trying to prevent the complications that cause these people to die.”
